Abstract

The electrochemical properties of spine LiMn₂O₄ synthesized via a solid state reaction were investigated. Electrolysis MnO₂(EMD), Li₂CO₃ ,LiOH and LiNO₃ were used as the initial materials. It was found that the electrochemical properties of LiMn₂O₄ were strongly influenced by the synthesis conditions. The LiMn₂O₄ sample sprepared via the reactionof EMD and LiNO₃ showed the best properties for a lithiumion intercalation reaction. The procedure includes two steps:pretreatment at 280 ℃ for 6 hours to initiate the permeation of melting LiNO₃ into the microporesof EMD particles, followed by sintering at 750 ℃ for 24 hours.
