摘要：

Monodispersed Li2MnSiO4 nanoparticles are synthesized via a supercritical solvothermal method at 300 degrees C for 5 min reaction time. The as-synthesized nanoparticles are free from impurities and have 15-20 nm diameter. After coating with conductive polymer, a discharge capacity of 313 mA h g(-1) is obtained for the first time because of nearly 2Li(+) reaction.
