Abstract
Electrodes based on the layered compounds have been charged in the electrolyte, 1 m in ethylene carbonate/diethyl carbonate (1:2 v/v). Initially removal is accompanied by oxidation of to Once all Mn is in the 4+ oxidation state further removal occurs by two unconventional mechanisms, one involving oxidation of with subsequent O loss (effective removal of and the other electrolyte oxidation generating which exchanges for in the electrode. Although both mechanisms appear to occur at 30 and 55°C, the former dominates at both temperatures in contrast to © 2003 The Electrochemical Society. All rights reserved.Keywords
