Improve the battery's voltage, thereby enhance the safety of battery.5. The reversible capacity of spinel LiMn2O4 battery material improved by nano alumina is 107mAh / g.And its capacity-keeping rate is 90% min which is better than the similar products in the world.Nano alumina is the first materials used in high-power Li-ion battery. Dosage 0.2-5%Package 15kgs/carton
