Upgrading Li-battery performance via nanotechnology

摘要

@@ Lithium batteries,as a main or back-up power source for mobile communication devices,portable electronic devices and the like,have attracted much attention in the scientific and industrial fields due to their high electromotive force and high energy density.To meet the demand for batteries with higher energy density and improved cycle characteristics in recent years,many attempts have been made to develop new electrode materials or design new structures of electrode materials.
