In this work structural and transport properties of layered LiNi1-y-zCoyMnzO2 (y=0.25, 0.35, 0.5 and z=0.1) cathode materials are presented. In the considered group of oxides, LiNi1-y-zCoyMnzO2, there is no clear correlation between electrical conductivity and the a parameter(M-M distance in the octahedra layers). A non-monotonic modification of electrical properties of LixNi0.65Co0.25Mn0.1O2 cathode materials is observed upon lithium deintercalation. (C) 2009 Elsevier B.V. All rights reserved.
