Abstract: Li2MnSiO4, as a novel lithium ion battery cathode material, is promising due to its wide source, low cost, environmental benign and high specific capacity. In this paper the crystal structure, electrochemical performance and the synthesizing methods of Li2MnSiO4 were presented. Aiming at the defects, such as low electronic conductivity and unstable crystal stability, some improvements were proposed, such as carbon coating and metal doping. Finally the prospect of application tendency was depicted.
