Claim Text:
1. Mixed oxide containing a) a mixed-substituted lithium manganese spinel as a first constituent in which a first portion of the manganese lattice sites are occupied by lithium ions and b) a boron-oxygen constituent as a second constituent, wherein the mixed oxide is a single-phase homeotype mixed crystal comprising the two constituents wherein the second constituent is in the same phase as the first Constituent, and wherein the mixed oxide has a composition satisfied by the following formula:  wherein 0≦a<0.1; d ≦1.2 3.5<×<4.5; 0.01<c<0.06 z=1, 2 or 4 y=1, 2, 3 or 7 u=0, 1, 2 or 3 v=0, 1, 2 or 3 0.01<b<0.5 M is at least one element selected from the group of Zn, Mg, and Cu; N is at least on element selected from the group of Al, Mg, Zn, Co, Ni, Cu and Cr; and X is at least one element selected from the group Li, Na, K, wherein in the mixed-substituted lithium manganese spinal, and second portion of the manganese lattice sites are occupied by mental ions of N selected from at least one of Ni and Co, wherein either “d” of Ni is 0.5+/−0.1 or “d”of Co is 1+/−0.2, and the size of the primary crystallites of the mixed oxide, measured as D
