| Abstract: | The surface of spinel LiMn 2O 4 has been modified through heat treatment of a coating of sol gel and its structure and performance were investigated. It was shown that the dissolution of Mn ions in spinel in the electrolyte could be reduced dramatically by this means,the cycle performance of batteries was improved and the Jahn Teller effect could be suppressed. |
