✦ Synopsis

Electrochemical behavior of Li,Mn,O, powders, prepared using different synthesis approaches, have been studied using LixC,/LirMn,O, cells based on glass-polymer composite electrolytes. Results indicate that the LiXMn,O, powders prepared by a xerogel technique have much smaller particle size, larger capacity utilization and less capacity fading during cycling in comparison to the powders prepared by solid state reactions. The electrochemical behavior of a composite positive electrode based on Li,Mn,O, is influenced not only by the microstructure of the LirMn,O, powders but also by the volume fractions of other constituent phases.
