Abstract
Electrochemically active material comprising a lithium metal oxide composition approximately represented by the formula LiCoNiMnO, where −0.2≤b≤0.2, 0.2≤m≤0.45, 0.055≤n≤0.24, 0.385≤p≤0.72, and m+n+p is approximately 1 has been synthesized and assembled to batteries. The electrochemical performance of the batteries was evaluated. The lithium metal oxide composition in general comprises a first layered phase, a second layered phase and a spinel phase. A layered LiMnOphase is at least partially activated upon charging to 4.5V. In some embodiments, the material further comprises a stabilization coating covering the lithium metal oxide composition.
