摘要
The solid-state reaction was employed to obtain LiBOB in vacuum dryer at 100 degrees 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 theta 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.
