Synthesis of Li2FeSiO4/C composite cathode material for Li-ion batteries and influence of dispersion effect on electrochemical characteristics

A critical review on orthosilicate Li2MSiO4 (M = Fe, Mn) electrode materials for Li ion batteries

“…Additionally, LMS/C7 delivered initial charge capacity of 240 mAh g −1 , which is discovered to be 66% greater than pure-LMS (90 mAh g −1 ) at 10 mA g −1 current density at room temperature. LMSC7 delivered initial discharge capacity of 188 mAh g −1 which was higher than pure Pushnitsa et al [218] synthesized LFS with special morphology. After grinding the particles, the effect of morphology and particle size were observed on electrochemical performance of LFS.…”

The recent progress of Li 2 FeSiO 4 as a poly‐anionic cathode material for lithium‐ion batteries

“…After heat treatment, the morphology after grinding in a ball mill (Figure 18) and the influence of particle size on its electrochemical properties were studied. 48 The results show that the discharge capacity of cathode material increases from 129 to 145 mAh/g under the condition of C/10 current after grinding, and it becomes 137 mAh/g after 100 charge-discharge cycles. They also point out that in order to select the part of Li 2 FeSiO 4 material with the best electrochemical characteristics, we should implement the strategy of size separation and evaluation of the…”

“…The SEM images of unground LFS/C (A, B) and ground LFS/C (C, D) 48 uniformity of carbon coating on the material particles, which provides a new idea for further research of Li 2 FeSiO 4 material.…”

Status and outlook for lithium-ion battery cathode material synthesis and the application of mechanistic modeling

“…It is emphasized that different parameters of the sol-gel synthesis such as precursors, sintering temperature and time had significant effect on the electrochemical performance. Other CAMs including layered: LNO [15], NCA [14]; spinel: LMO [16,62], LNM [17,18,50]; orthosilicate: LFS, LiFeSO 4 /C [63,64]; and tavorite: Li 2 CoPO 4 F/C [65] have also been generated through the sol-gel route.…”
