In this paper,the discharge capacity,stability voltage and the ratio of constant current charge capacity and battery discharge capacity of lithium ion battery were studied. For the lithium manganese lithium-ion batteries,the discharge capacity,mid-value voltage and stability voltage all increased with increasing charge cutoff voltage. As long as charge cutoff voltage was no less than 4.15 V,the battery discharge capacity loss would not exceed 6%. When charge cutoff voltage was 4.15V,the constant current charge capacity accounted for more than 85% of total charge capacity,a little change from 4.20 V.

For Et4NBF4/AN, the least ionic transfer and diffusion resistance led to an excellent capacitance retention property. For Bu4NBF4, due to the larger solvated ion diameter and higher ion transfer resistance, the capacitive performances were inferior to those of Et4NBF4 in terms of specific capacitance and power density.
