Research Trends

Based on the literature data on the discharge characteristics of Li₄Ti₅O₁₂ (LTO) and LiNi_1/3Co_1/3Mn_1/3O₂ (NMC) electrodes at different temperatures, the discharge curves of batteries composed of LTO and NMC electrodes were calculated. Four models of a battery based on the pristine materials and their modifications (an LTO anode based on a synthesized Cu/Super-P composite and an NMC cathode modified with lithium boron oxide glass (LBO)) are considered. The effect of modification of electrode materials on the temperature dependence of their capacity is estimated. It was found that a battery with a NMC-based cathode modified with LBO coating has good low-temperature properties and that the cathode modification in its effect on the discharge capacity exceeds the effect of the anode modification. It is shown that a battery with two improved electrodes is superior to other options in the entire temperature range from −30 °C to +20 °C.
