Abstract
The layered rocksalt-type oxide, Li2PtO3, is the first full 4 V class catho de material among 5d metal compounds. We investigated the electrochemical, structural and kinetic characteristics of the 4 V region. The volumetric ca pacity of the 4 V plateau on discharge was comparable to that of LiCoO2. Mo reover, the volume change during cycling was less then that of LiCoO2. We m easured the total conductivity and Li diffusivity in Li2PtO3 by the ac impe dance and current-pulse relaxation techniques, respectively. (C) 1999 Elsev ier Science Ltd. All rights reserved.
