摘要
The present invention relates to a method for improving the lifetime of a manganese oxide-based electrode using elemental substitution. More specifically, it is a cathode material for a lithium ion secondary battery, and its price is very low compared to conventional materials, but the life during charging / discharging of the electrode (Cycle life) The present invention relates to a method for improving the lifetime of manganese oxide having poor properties.;The present invention not only stably prepares the electrode in the air by liquid phase substitution of manganese in the oxide composition, but also is cheaper than conventional alkoxide-based compounds, and is economically economical. There is an advantage to this. In addition, the lithium ion secondary battery manufactured according to the present invention has excellent electrode life at both room temperature and high temperature.
