Lithium bis(trimethylsilyl) phosphate as a novel bi-functional additive for lithium ion batteries |
| abstract |
This work investigates the beneficial roles of lithium bis(trimethylsilyl) phosphate (LiTMSP) which may act as a novel bifunctional additive for lithium ion batteries, in particular, LiNi0.5Mn1.5O4 (LNMO)/graphite cells. The cycle performance of LNMO/graphite cells is significantly improved with incorporation of LiTMSP. Trimethylsilyl functional group therein can react with HF generated through hydrolysis of LiPF6 by residual water in electrolyte solution, followed by a decrease in the concentration of metal ions dissolution from the electrode. The generation of superior passivating surface film derived by LiTMSP on graphite electrode, suppressing further electrolyte reductive decomposition and deterioration/reformation caused by migrated metal ions, is confirmed. Furthermore, LiTMSP derived surface film is likely to have better lithium ions conductivity with a decrease in resistance of the graphite electrode, improving rate performance of cells. The HF scavenging and film-forming effects of LTMPS are responsible for the less polarization of cells enabling to improve cycle performance. |
