Abstract
A significant improvement in thermal stability of the charged with a particle size of has been achieved by coating its particle surface with . An onset temperature for thermal decomposition of the prepared by heating at was , whereas that of the bare is . In addition, the coating also improved the capacity retention on cycling at charge cut‐off significantly. These results appear to indicate that the coating is effective in retarding the decomposition reaction of with the electrolytes as well as sustaining its structural stability on cycling. ©1999 The Electrochemical SocietyKeywords
