Carbon Coated Porous Aluminum Foil Anode for High Rate, Long Term Cycling Stability, and High Energy Density Dual Ion Batteries.
A 3D porous Al foil coated with a uniform carbon layer (pAl/C) is prepared and used as the anode and current collector in a dual ion battery (DIB) The pAl/C graphite DIB demonstrates superior cycling stability and high rate performance, achieving a highly reversible capacity of 93 mAh g 1 after 1000 cycles at 2 C over the voltage range of 3.0 4.95 V. In addition, the DIB could achieve an energy density of 204 Wh kg 1 at a high power density of 3084 W kg 1
