Electronic and electrochemical properties of LixNi1-yCoyO2 cathode material

This studies are devoted to structural, electrical and electrochemical investigations of LixNi1-yCoyO2 system. A modification of electrical properties of the cathode material was observed upon deintercalation. A correlation between electronic properties and effectiveness of lithium deintercalation process was confirmed. (C) 2002 Elsevier Science B.V. All rights reserved.
