LiNi0.9Co0.05Mn0.025Mg0.025O2 prepared by sol–gel method using citric acid had a well ordered hexagonal layered structure and showed excellent electrochemical performance.
A Li4Ti5O12/TiO2/carbon (Li4Ti5O12/TiO2/C) nanocrystalline composite has been successfully synthesized by a facile sol–gel method and subsequent calcination treatment.
The electrochemical performance results show that the highest capacities, 208 (0.2 C), 198 (0.5 C), 189 (1 C), 179 (2 C), 157 mA h g−1 (5 C), are obtained from the LTOV06 electrode, which are higher than those of the LTO electrodes reported.
A biocarbon coated Li3V2(PO4)3 (LVP-C) cathode with high electrochemical performance was synthesized by a sol–gel method using recycled tea as both structural template and carbon source.
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.
