hereinafter , various embodiments of the present invention will be explained in more detail with reference to the accompanying figures . however , it is understood that the present invention should not be limited to the following preferred embodiments set forth herein . in order to overcome the problems and disadvantages of a separator used in the conventional electrolytic capacitor including a liquid electrolyte , various examples of the preparation of a gel type ionic conducting polymer electrolyte separator of the present invention are provided as follows : preparation of a gel type ionic conducting polymer electrolyte separator by using propylene carbonate ( pc ) including tetraethylammoniumtertafluoroborate ( et 4 nbf 4 ) for manufacturing a gel type ionic conducting polymer electrolyte separator , 1 mole ( i . e ., 7 g ) of tetraethylammoniumtertafluoroborate ( et 4 nbf 4 ) is dissolved into 32 g of common solvent . in the present example , the common solvent is propylene carbonate ( pc ) which dissolves the polymer and functions as an electrolyte . subsequently , the polymer consisting of 3 g of polyacrylonitrile ( pan ) and 1 g of polyvinylidenefluoride ( pvdf ) is homogeneously dissolved in the common solvent at the room temperature to form a mixture of the common solvent and polymer . after the mixture is heated at 120 ° c . for one hour , the mixture is coated on a current collector to form a gel type ionic conducting polymer electrolyte separator . table 1 shows ionic conductivities of the conventional ionic conducting electrolyte separator and the gel type ionic conducting polymer electrolyte separator according to the present example . as shown in table 1 , the gel type ionic conducting electrolyte separator has an excellent ionic conductivity of about 4 . 30 ms / cm which is twice higher than the ionic conductivity of the conventional ionic conducting polymer electrolyte separator . when the thickness of the gel type ionic conducting polymer electrolyte separator is reduced to approximately 25 μm , the ionic conductivity of the gel type ionic conducting polymer electrolyte separator may increase up to 6 . 02 ms / cm since the ionic conductivity of the electrolytic separator is linearly in inverse proportion to the thickness of the electrolyte separator . preparation of a gel type ionic conducting polymer electrolyte separator by using pc including et 4 nbf 4 in this example , 1 mole ( 7 g ) of et 4 nbf 4 is dissolved into 32 g of pc as common solvent which dissolves the polymer and functions as an electrolyte like example 1 . here , the polymer is composed of 1 g of pan and 2 g of polymethylmethacrylate ( pmma ), which belongs to the polymer of polyacrylate series . after the polymer is homogeneously dissolved in the common solvent at the room temperature to form a mixture of the common solvent and polymer , the mixture is heated at 120 ° c . for 40 minutes for homogeneous viscosity . subsequently , the mixture is coated on a current collector to form a gel type ionic conducting polymer electrolyte separator . when the pmma and the pan are dissolved in the pc with et 4 nbf 4 , the gel type ionic conducting polymer electrolyte separator produced ionic conductivity of 5 . 0 ms / cm . in other words , the polymer electrolyte separator of the present example having thickness of 35 μm shows better ionic conductivity than that of the polymer electrolyte separator of example 1 . preparation of a gel type ionic conducting polymer electrolyte separator by using gamma - butyrolactone ( γ - bl ) including tertiary amide . in the present example , gamma - butyrolactone ( γ - bl ) including tertiary amide is used as common solvent instead of pc with et 4 nbf 4 . after 1 mole ( 4 g ) of tertiary amide is dissolved into 20 g of ( γ - bl which functions as the common solvent , the polymer consisting of 4 g of pan is homogeneously dissolved into γ - bl to form a mixture of the common solvent and polymer . after the mixture is heated at 110 ° c . for one hour , the mixture is coated on a current collector and cooled at the room temperature to form a gel type ionic conducting polymer electrolyte separator having thickness of 35 μm . the gel type ionic conducting polymer electrolyte separator of the present invention has ionic conductivity of 2 . 74 ms / cm which is lower than that of the separator manufactured by using pc with et 4 nbf 4 . the gel type ionic conducting polymer electrolyte separator of the present example can be homogeneously mixed with pan because γ - bl has a higher affinity with pan compared to that with pc . also , the gel type ionic conducting electrolyte separator of the present example has the ionic conductivity lower than that of example 1 or 2 due to the increase of the viscosity of ion conducting medium . preparation of a gel type ionic conducting polymer electrolyte separator by using pc and γ - bl with et 4 nbf 4 . after polypropylene carbonate including et 4 nbf 4 and gamma - butyrolactone having et 4 nbf 4 are mixed by the weight ratio of 1 : 1 , polymer composed of the polyacrylate series and polyether series is dissolved to manufacture a gel type ionic conducting polymer electrolyte separator . in the present example , the polymer is composed of polyacrylonitrile , polyvinylidenefluoride and polyethylene oxide . when the common solvent is only comprised of the γ - bl with et 4 nbf 4 , the ionic conducting polymer electrolyte separator failed to reach a gel state after the mixture of common solvent and polymer was coated on a current collector . hence , pc is mixed with γ - bl to form the gel type ionic conducting polymer electrolyte separator . in the present example , the weight ratio between pan and pvdf is preferably 1 : 1 to 5 : 1 when pc with et 4 nbf 4 is mixed with γ - bl as the common solvent . if the gel type ionic conducting polymer electrolyte separator includes pan in accordance with such ratio , the ionic conductivity of the gel type ionic conducting polymer electrolyte separator greatly decreases . also , the mechanical strength of the gel type ionic conducting polymer electrolyte separator decreases , such that an electrolytic capacitor cannot be formed when the gel type ionic conducting polymer electrolyte separator includes a certain quantity of the pan which fails to meet such ratio . although the mixture of common solvent and polymer are mainly described in the above examples , diethylcarbonate ( dec ), dimethyl carbonate ( dmc ), ethymethyl carbonate ( emc ) or ammoniumdihydrogenphospate can be also added to the common solvent to enhance low and high temperature characteristics and the ionic conductivity of the electrolytic capacitor , respectively . however , the characteristics and the manufacturing processes of the polymer electrolyte will not be changed by those additives since the characteristics and the manufacturing processes of the gel type ionic conducting polymer electrolyte are determined by the common solvent and polymer . in addition to the examples for preparing the gel type ionic conducting polymer electrolyte separator as set forth above in examples 1 - 4 of the first embodiment , an additional electrolyte having excellent ionic conductivity is injected into electrodes and a gel type ionic conducting polymer electrolyte separator after the electrodes and the gel type ionic conducting polymer electrolyte separator are wound to form an electrolytic capacitor . gamma - butyrolactone or acetonitrile ( ch 3 cn ) including the above - mentioned solution such as et 4 nbf 4 is used as the additional electrolyte . regarding the electrolytic capacitor having the gel type ionic conducting polymer electrolyte separator manufactured by the above - described examples , the electrolytic capacitor normally works when the gel type ionic conducting polymer electrolyte separator is sufficiently thick . this is due to the fact that the gel type ionic conducting polymer electrolyte can permeate into the electrodes and into the interface between the electrodes and the gel type ionic conducting polymer electrolyte separator . if the thickness of the gel type ionic conducting polymer electrolyte separator is insufficient , the operation of the electrolytic capacitor may be limited . thus , additional electrolytes may be injected to enhance the performance of the electrolytic capacitor . in this case , the additional electrolytes may be identical to the common solvent for manufacturing the gel type ionic conducting electrolyte separator or may be different from the common solvent of the gel type ionic conducting electrolyte separator . if the additional electrolyte differs from the common solvent of the gel type ionic conducting electrolyte separator , the performance of the electrolytic capacitor may improve since the common solvent of the gel type ionic conducting electrolyte separator and the additional electrolyte can act separately . in one example of the present embodiment , the acetonitrile in which 1 mole of et 4 nbf 4 is dissolved is additionally injected into the electrodes and the gel type ionic conducting electrolyte separator , while pc including 1 mole of et 4 nbf 4 is used as common solvent during the manufacturing process for the gel type ionic conducting polymer electrolyte separator . also , γ - bl with et 4 nbf 4 is used as an additional electrolyte according to another example of the present embodiment . furthermore , pc including et 4 nbf 4 can be injected as the additional electrolyte , thereby enhancing the performance of the electrolytic capacitor of the present embodiment . according to the present embodiment , in case that pc including et 4 nbf 4 is used as the common solvent and also used as the additional electrolyte which is injected into the electrodes and the gel type ionic conducting electrolyte separator , the electrolytic capacitor has a resistance of 20 mω at the resonance frequency of the capacitor . at that time , the electrolytic capacitor has diameter of 10 mm and height of 30 mm . on the other hand , the resistance of the electrolytic capacitor having the same dimension of the above capacitor is 15 mω at the resonance frequency when the acetonitrile including et 4 nbf 4 is injected as the additional electrolyte after pc including et 4 nbf 4 is used as the common solvent of the gel type ionic conducting polymer electrolyte separator . therefore , the electrolytic capacitor shows a superior performance when the common solvent and the additional electrolyte are different from each other . in the present embodiment , a method for directly coating the gel type ionic conducting polymer electrolyte separator onto an electrode of an electrolytic capacitor will be described . it is advantageous to have the gel type ionic conducting polymer electrolyte separator coated on the electrode . in other words , when the gel type ionic conducting polymer electrolyte separator is directly coated on the electrode after the gel type ionic conducting polymer electrolyte separator is prepared , the coating process is simply accomplished in comparison with the conventional process for attaching the separator to the electrode . in addition , when the gel type ionic conducting polymer electrolyte separator is directly coated on the electrode , the gel type ionic conducting polymer electrolyte forms a film . thus , the adhesion strength between the gel type ionic conducting polymer electrolyte separator and the electrode greatly increases to enhance the interface adhesion between the gel type ionic conducting polymer electrolyte separator and the electrode . specifically , when the gel type ionic conducting polymer electrolyte separator is directly formed on a powder type activated carbon which is coated on an electrode , a composite of the gel type ionic conducting polymer electrolyte and the activated carbon is formed since the gel type ionic conducting polymer electrolyte becomes a film after the gel type ionic conducting polymer electrolyte is permeated into pores of the activated carbon . thus , the interface adhesion between the gel type ionic conducting polymer electrolyte and the electrode can greatly increase and the activated carbon can be solidly attached to the electrode by forming the composite of the gel type ionic conducting polymer electrolyte and activated carbon . in order to increase the storage capacitance of an electrolytic capacitor having an ionic conducting electrolyte , the etching ratio of a metal of an electrode should be increased since the resistance of the electrode may increase when the etching ratio of the electrode increases . however , the electrolytic capacitor can have a thin electrode having a large capacitance if an electrode includes an activated carbon which is coated on a current collector as a cathode of the electrolytic capacitor . the activated carbon is a porous material which has a specific surface area of approximately 2 , 000 m 2 / g . the cathode of the electrolytic capacitor may have a storage capacitance of over 10 mf / cm 2 when the activated carbon having thickness of approximately 0 . 01 mm is coated on the cathode . in light of such problems , the cathode of the related art including the etched metal has a storage capacitance of approximately 0 . 5 mf / cm 2 . however , the cathode including the activated carbon can have a storage capacitance twenty times larger than that of the cathode of the related art including the etched metal . in the present embodiment , the cathode of the electrolytic capacitor is manufactured by coating the activated carbon on the current collector and by directly forming the gel type ionic conducting polymer electrolyte in the pores and on the surface of the activated carbon . therefore , the electrolytic capacitor can have an excellent storage capacitance and exceedingly enhanced performance because of the thin cathode and greatly increased capacitance . the gel type ionic conducting polymer electrolyte separator also has a superior mechanical strength and high ionic conductivity . for example , the 6 . 3v electrolytic capacitor of the related art has a storage capacitance of about 2 . 2 to 3 . 3 mf when the electrolytic capacitor has diameter of 13 mm and height of 20 mm . the electrolytic capacitor of the present invention , however , has a storage capacitance of 5 mf when the electrolytic capacitor of the present invention has the dimension identical as that of the conventional electrolytic capacitor . the electrolytic capacitor of the present embodiment includes a cathode manufactured by directly coating 0 . 03 mm of the gel type ionic conducting polymer electrolyte separator on a cathode previously manufactured by coating 0 . 015 mm of an activated carbon on an aluminum foil having thickness of 0 . 02 mm . an anode of the electrolytic capacitor has an oxide layer formed thereon . because the anode having the oxide layer may be damaged during the manufacturing process , the oxide layer is recuperated by applying a predetermined voltage to the electrolytic capacitor for an aging process after the electrolytic capacitor is completed . gas is generated during the recuperation of the oxide layer . if the gel type ionic conducting polymer electrolyte separator is directly coated on the anode , the storage capacitance of the electrolytic capacitor may reduce and the resistance of the electrolytic capacitor may increase since the gas generated during the aging process is confined between the anode and the gel type ionic conducting polymer electrolyte separator . in order to prevent such problems , it is more advantageous to directly coat the gel type polymer electrolyte separator on the cathode of the electrolytic capacitor . in the present embodiment , a method for winding electrodes and separator of an electrolytic capacitor will be described as follows : fig3 is a schematic perspective view illustrating the winding of an electrolytic capacitor according to the related art . referring to fig3 in the electrolytic capacitor of the related art including porous paper or polyproplene as a separator , electrodes 65 and 75 and separators 60 and 70 , respectively , are wound together wherein widths of the first and second separators 60 and 70 are respectively wider than those of the anode 65 and the cathode 75 to prevent an electrical short between the anode 65 and the cathode 75 . however , in the present embodiment , the electrode having the gel type ionic conducting polymer electrolyte separator should be wider and longer than the other electrode , respectively , so as to prevent the electrical short between the electrodes of the electrolytic capacitor in case of using the gel type ionic conducting polymer electrolyte separator . that is , the width of the gel type ionic conducting polymer electrolyte separator does not need to be larger than the electrodes as the separators of the related art in fig3 . one of the variations of this embodiment is that a gel type ionic conducting polymer electrolyte film may be attached to the electrode after the gel type ionic conducting polymer electrolyte is coated on a substrate to have a film shape followed by attaching the substrate , which is a separator , on an electrode . however , such manufacturing process demands more cost and excessive processing time . fig4 is a plain view showing electrodes of the electrolytic capacitor having the gel type ionic conducting polymer electrolyte separator according to one embodiment of the present invention . as shown in fig4 in order to prevent the electrical short between one electrode and the other electrode having the gel type ionic conducting polymer electrolyte separator , width and length of a second electrode 105 are respectively shorter than those of a first electrode 100 . the gel type ionic conducting polymer electrolyte separator is coated on the first electrode 100 . as mentioned above in the third embodiment , the gel type ionic conducting polymer electrolyte separator is preferably coated on the cathode of the electrolytic capacitor . stated differently , it is advantageous to coat the gel type ionic conducting polymer electrolyte separator on the cathode , which has wider width and longer length that those of the anode . fig5 is a schematic view illustrating a process for winding the anode and the cathode with the gel type ionic conducting polymer electrolyte separator according to a preferred example . the electrical short between the electrodes may occur when the end portion of the electrode having the gel type ionic conducting polymer electrolyte separator is located at the end portion of the other electrode during the process of winding the electrodes . referring to fig5 a first electrode 120 having the gel type ionic conducting polymer electrolyte separator is previously wound by at least half a revolution , and then the first electrode 120 is wound with a second electrode 125 . the first electrode 120 is longer than the second electrode 125 at the winding starting position . simultaneously , the first electrode 120 is also longer than the second electrode 125 at the ending position . the cathode is initially wound by at least half a revolution , and then the cathode and the anode are wound together . also , the cathode is further wound by at least half a revolution after the winding of the anode is completed . fig6 is a schematic view illustrating the process for winding the anode and cathode having the gel type ionic conducting polymer electrolyte separator according to another preferred example . as shown in fig6 in order to prevent the electrical short between first and second electrodes 130 and 135 at the winding position , the end portion of the first electrode 130 is covered with an insulating member 140 . the gel type ionic conducting polymer electrolyte separator is formed on the first electrode 130 . the insulating member 140 can be a paper , a tape or other insulating materials . also , the insulating member 140 can be formed on a portion of the second electrode 135 where the end portion of the first electrode 130 is positioned to prevent the electrical short between the electrodes 130 and 135 . when the electrodes 130 and 135 are wound with the insulating member 140 , the electrical short between the electrodes 130 and 135 cannot occur even though the end portion of the first electrode 130 is located at the end portion of the second electrode 135 . meanwhile , in case where the gel type ionic conducting polymer electrolyte separator is used , the electrolytic capacitor can introduce various shapes , such as a square pillar , a rectangular pillar , a triangular pillar or a pentagonal pillar along with a cylindrical shape , because the gel type polymer electrolyte separator is directly coated on the electrode of the electrolytic capacitor . fig7 is a schematic perspective view showing a multi layer type electrolytic capacitor according to the present invention . referring to fig7 when the electrolytic capacitor is a multi layer type , the gel type ionic conducting polymer electrolyte separators formed on first electrodes 150 also work as bonding agents between first electrodes 150 and second electrodes 155 , thereby easily accomplishing the process of stacking the electrodes 150 and 155 , alternately . according to the present invention , the unit storage capacitance of the electrolytic capacitor can be greatly increased but the size of the electrolytic capacitor is decreased by using the gel type ionic conducting polymer electrolyte separator . also , the electrolytic capacitor reduces the resistance by the gel type ionic conducting polymer electrolyte separator so that the electrolytic capacitor enables enhancement of high frequency response characteristic , enlargement of the available frequency region of the capacitor and increase of the allowable ripple current of the capacitor . although the preferred embodiments of the invention have been described , it is understood that the present invention should not be limited to those preferred embodiments , but various changes and modifications can be made by one skilled in the art within the spirit and scope of the invention as hereinafter claimed .
