Abstract

Lithium cobalt mixed doped lithium manganese spinels Li-1(Mn1.9-xCo0.1Lix)O-4 (0 less than or equal to x less than or equal to 0.1) were prepared by heat treatment (750 degrees C for 12 h) of solution precipitated precursors. Samples were characterised structurally and electrochemically by XRD and galvanostatic cycling. Permanent cycling, storage in the charged state, andstorage in the discharged state were tested. Under the cycling conditions of this study, mixed doped lithium manganese spinels present better cyclingand storage stabilities than a respective Go-doped spinel. There are hintsfor a considerable occupation of site 16c by lithium ions. The electrochemical behaviour is similar to that of an undoped spinel for low values of x and is similar to that of lithium doped spinels for high values of x. (C) 1999 Elsevier Science S.A.
