Abstract：Through the high_temperature storage,the open_circuit voltage,resistance,self_dis_charge rate and capacity was tested intermittently to investigate the high_temperature storage per_formance of Li_ion battery.The results showed that,after storage at 45 ℃ for 13 days,the self_discharge rate and open circuit voltage of the fully charged battery declined in different degrees, the self_discharge rate and open circuit voltage were nonlinear,the self_discharge rate of the fully charged battery would contribute to filtration for module battery,the resistance changes of the fully charged and empty batteries were not obvious,the open_circuit voltage variation of empty batteries would contribute to filtration.
