A citric acid method to prepare LiMn2O4 for lithium-ion batteries
Abstract A new simplified technique (citric acid method) has been adopted to synthesize LiMn 2 O 4 , and the influence of synthesis conditions on the electrochemical properties of the products has also been studied. The Li/Mn ratio and synthesis temperature are the key factors to affect the electrochemical characteristics of the resultant products. The LiMn 2 O 4 synthesized with the optimum synthesis conditions has a perfect spinel structure and shows excellent performance.
