    Abstract: A method for manufacturing LiMn2O4 powders for use in a lithium secondary battery positive electrode, is provided, in which oxide or carbonate is used as a positive electrode material, a solution is dried at a temperature higher than 150° C., and the resulting matter is put into a reaction furnace in order to be calcinated for a short time, after treating by spontaneous combustion. A certain degree of crystallization of the positive electrode powders can be obtained in the spontaneous combustion process. Thus, a battery having a large charging and discharging capacity and a long life cycle can be manufactured even under a high current condition.

    Abstract translation: 提供一种用于锂二次电池正极的LiMn 2 O 4粉末的制造方法,其中使用氧化物或碳酸盐作为正极材料,将溶液在高于150℃的温度下干燥,并将所得物质 放入反应炉中,以便在通过自燃处理后短时间内煅烧。 在自燃过程中可以获得正电极粉末的一定程度的结晶。 因此,即使在高电流条件下也可以制造具有大的充放电能力和长寿命的电池。
