MIXED OXIDE CONTAINING A LITHIUM-MANGANESE SPINEL AND PROCESS FOR ITS PREPARATION

摘要

The present invention relates to a mixed oxide comprising a) a lithium-manganese spinel which has mixed substitution and in which part of the manganese lattice sites are occupied by lithium ions and b) a boron-oxygen compound. The present invention further relates to a process for producing it and the use of the mixed oxide as electrode material for lithium ion batteries.
