A novel form of the insertion compound having the formula LixMn2O4 and a tetragonal crystal structure has been synthesized wherein x is a number in the range from about 1.7 to about 2.1. The insertion compound has a voltage relative to Li/Li+ in the range from about 3.2 to about 3.8 V and is thus air stable. The insertion compound is useful as an electrode material for lithium ion batteries. In particular, the insertion compound can be used as a cathode additive to result in a cathode limited construction. In certain applications, this can result in improved tolerance to overdischarge. |
