    摘要: In order to provide a novel spinel type lithium transition metal oxide (LMO) having excellent power performance characteristics, in which preferably both the power performance characteristics and the cycle performance at high temperature life characteristics may be balanced, a novel spinel type lithium transition metal oxide with excellent power performance characteristics is proposed by defining the inter-atomic distance Li—O to be 1.978 Å to 2.006 Å as measured by the Rietveld method using the fundamental method in a lithium transition metal oxide represented by the general formula Li1+xM2−xO4 (where M is a transition metal consisting of three elements Mn, Al and Mg and x is 0.01 to 0.08).
