Abstract: Anode materials, electrolyte and voltage are studied to define the ideal system for LiMn₂O₄-based lithium-ion power battery. It is concluded that low cost natural graphite presents as an ideal anode material for LiMn₂O₄-based lithium-ion power battery; the improved electrolyte prolongs the cycle life for 200 cycles; and LiMn₂O₄-based lithium-ion power battery presents the best stability and the longest cycle life under the voltage range between 3.0V and 4.2V LiMn₂O₄-based lithium-ion power battery based on the above system presents excellent performance such as high safety, long cycle life, high performance under high and low temperatures as well as superior storage performance.

Key words: LiMn₂O₄-based lithium-ion power battery, system, performance tests
