| Abstract: | The conductivity of LiBOB based electrolyte, which we formed in our lab, has been compared with commercialized LiPF6 based electrolyte firstly. The charge and discharge capacity of the LiFePO4/Li half-cell with two kind of electrolyte has compared both at room temperature and elevated temperature. LiBOB cell presented better charge/discharge stability at elevated temperature than the counterpart. ICP method was adopted to analyze the reaction of electrolytes with cathode material at high temperature. Cyclic voltammogram was conducted to analyze the charge/discharge process of the cell in both LiBOB based electrolyte and LiPF6 based electrolyte at different temperature. |
