Sol Gel Method

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.
