It suggests that the TGO usually consists of a great number of chromium oxides, cobalt oxides and spinel oxides besides alumina during the initial period of the high...; while the CoCr2O4 spinel oxides are usually formed under the conditions of higher partial pressure of oxygen during the initial period and the lower partial pressure of oxygen during the subsequent......
Recently, several research groups have reported transition-metal-substituted spinel materials (LiMxMn2-xO4, M: Cr, Co, Fe, Ni, Cu) with high-voltage plateaus above 4.5V[1-5]. Among these materials... far, however, there is no literature about the influence of ball milling and electrolyte on the property of LiNi0.5Mn1.5O4 spinel. In the present paper, therefore, the effect of ball milling......
