Synthesis of novel nanostructured composite cathode materials for lithium-ion batteries using mechanical activation

Abstract

The recent launching of production of hybrid and electric vehicles made great demands on lithium-ion batteries (LIBs).One of the promising approaches to the optimization of their properties is in the development of new blended composite electrode materials consisting of two (or more) active components in order to use the advantages of the both of them [1].Due to a unique combination of properties, the mixed materials show some advantages over the individual components.This includes the longer lifetime, the decreased capacity fading upon the cycling, lower price, the improved thermal stability, more acceptable profiles of charge-discharge curves and operating voltage, etc.For instance, the cathode materials with a layered structure (LiCoO 2 )
