Sodium phosphate additives and mixed electrolytes of Li(C2F5SO2)2N (LiBETI) and LiPF6 were examined to improve cycle performances of Li1.04Mn1.96 O 4 /graphite cells at high temperatures. The cycle performance of those cells exceeded 80% at 100 cycles at 55°C in an optimum combination of a 0.975 M LiBETI and 0.025 M LiPF6 /ethylene carbonate (EC):dimethylcarbonate (DMC) (1:2) electrolyte solution containing 5% of Na4P2O7 or 5% of Na5P3 O 10 additive. Such a cycle performance is considered to fulfill the requirement for practical use.
