Abstract

Manganese dioxide has for many years found widespread use as a cathode material in aqueous Leclanche, zinc chloride and alkaline cells and,more recently, in nonaqueous lithium cells. However, despite the large number of polymorphic structures that exist in the manganese dioxidefamily, the battery industry has used gamma-MnO2 exclusively as the positive electrode in these cells. With the advent of rechargeable lithium battery technology, research efforts have demonstrated that other MnO2 structures, when processed in the correct way, provide attractiveelectrochemical properties for lithium cells. In this paper, some recent advances that have been made in MnO2 materials technology are discussed, for example, in the development of alpha-MnO2, layered-MnO2, spinel-related Li2O.yMnO2 (y greater-than-or-equal-to 2.5) and ramsdellite-MnO2 materials. An attempt has been made to clarify issues relatingto the structural features of 'CDMO'-type materials that are preparedby the reaction of gamma-MnO2 with LiNO3 (or LiOH) at 300-400-degrees-C.
