Abstract

The solid-state reaction was employed to obtain LiBOB in vacuum dryer at 100°C, with the dryer of P2O5. The resulting LiBOB was employed in various ternary solvent blends to get the k, and its change with salt, solvent composition and temperature. 0.7 M LiBOB-PC/EMC/DMC (1: 1: 1, v: v: v) and 0.5 M LiBOB-EC/EMC/DMC (1: 1: 1, v: v: v) were observed to have better k at wide θ range, and the former was chosen to assemble Li/MCMB and LiFePO4/Li cells. The results indicated that it can stabilize the MCMB anodes, and exhibit good stability in LiFePO4/Li cell.
