Using literature information about the temperature effect on the electrochemical behavior of electrodes based on LiFePO4 and Li4Ti5O12 being positive and negative electrodes of a lithium­ion battery, the discharge characteristics of batteries with such electrodes and various ratios of the amount of active material on the electrodes in the temperature range from −15 to +60°C were calculated. It was established that as the temperature changed, the type of the dependence of the specific capacity of the battery, calculated on the total mass of active materials, on the ratio of the quantities of active materials on unlike electrodes changed.
