چکیده

Lithium Bis(trimethylsilyl) Phosphate (LiTMSP) was incorporated as an electrolyte additive in LiNi 0.8 Co 0.1 Mn O 2 (NCM811)/graphite cells for improving the low-temperature performance. Previously, we reported bi-functional roles of LiTMSP 0.5 1.5 4 /graphite cells, which are hydrogen fluoride (HF) scavenger and film-forming agent. In this work, NCM811/graphite with (1 wt%) have better rate performance at ?10 °C than without LiTMSP. This is due to reduced resistance addition LiTMSP, resulting from induced-surface film generated on graphite electrodes has improved lithium-ion conduction.

Microwave Crystallization of Lithium Aluminum Germanium Phosphate Solid-State Electrolyte

Lithium aluminum germanium phosphate (LAGP) glass-ceramics are considered as promising solid-state electrolytes for Li-ion batteries. LAGP glass was prepared via the regular conventional melt-quenching method. Thermal, chemical analyses and X-ray diffraction (XRD) were performed to characterize the prepared glass. The crystallization of the prepared LAGP glass was done using conventional heatin...
