[0027] in an argon-filled glove box (H 2 O<10ppm) to make the electrolyte solution for silicon negative electrode lithium battery, see Table 1 for the composition of the specific electrolyte solution.
[0028] Inject the electrolyte solution into a 1Ah lithium battery with lithium cobalt oxide as the positive electrode and silicon nanowire as the negative electrode, and charge and discharge the battery at 0.1C. At 25°C, charge and discharge at 1C for 100 cycles, and test the percentage of battery capacity and Battery expansion rate. The results are shown in Table 1.
