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.

However, for the collision processes in He target, a large discrepacy between the CTMC results and experimental measurement is found. As is well known, the microcanonical distributions of bounded electrons in CTMC method is quite different from quantal distributions, we modified the initial microcanonical distribution by using eleven different ionization thresholds of electron bounded in target. With modification, we calculated the collisional process of O~(3+) with He, and the total cross sections of all processess are calculated as a function of the incident energies. The agreement with experiments is improved by the modified distributions.
