[0023] Examples 1 to 11
[0024] Electrolyte: The lithium salt is lithium hexafluorophosphate, the molar concentration of the lithium salt is 1 mol / L, and the other components and dosages in the electrolyte are shown in Table 1.
[0025] Negative electrode: artificial graphite, positive electrode: lithium cobalt oxide material, the electrolyte, positive electrode, and negative electrode are assembled into a lithium battery according to conventional processes. For the comparison of the coulombic efficiency of the lithium battery prepared in Example 1 and Example 5, see figure 1 , Test the battery capacity percentage and battery expansion rate of the lithium batteries prepared in each embodiment after 300 cycles of charging and discharging. The results are shown in Table 1.
