Li₂MnSiO₄/C Composite with Ascorbic Acid as Carbon Source for Lithium Ion Batteries

Abstract:

Ascorbic acid (VC) was used as carbon source for Li₂MnSiO₄/C composite synthesized by a sol-gel method. By comparing the electrochemical performance of the Li₂MnSiO₄/C composite and pure Li₂MnSiO₄, it was found that VC adding can improve the capacity of Li₂MnSiO₄. The Li₂MnSiO₄/C with 10% VC shows a discharge capacity of 212 mAh/g at 0.05C and Li₂MnSiO₄/C with 15% VC shows discharge capacity of 192 mAh/g at 0.1C, that were higher than the capacity of pure Li₂MnSiO₄.
