Abstract

The embodiments of this disclosure provide a method and a device for managing battery data. The method comprises: acquiring cell data and battery data, which describe statuses of a cell and a battery pack, respectively; calculating an estimated battery status, which indicates a status of the cell and the battery pack after an estimation time period, based on the cell data and the battery data; sending an alarm message to a user if the estimated battery status meets a battery failure condition. With the method described above, the current battery data is effectively utilized to estimate the subsequent battery status to predict potential battery failure in advance, rather than recognize the failure from the detected battery data when the battery has failed. In this way, it is possible to avoid battery failures effectively, prevent the battery failures from impacting the quality of the battery, and improve the user experience of the battery.

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.
