A Simple Synthesis of N-doped Graphene-Mn304 Nanocomposites as High-Performance Anode Materials for Lithium Ion Batteries

摘要

Energy storage systems (ESS) with an long lifetime are needed to meet the increasing demands in various fields. Lithium ion battery (LIB) has attracted great attention as one of the most popular power sources owing to their high power and energy density. Developing advanced materials with high capacity for great lithium ion storage properties is very desirable. Graphite or carbon materials are generally used as anode materials in ordinary LIB. However, as this materials deliver a low capacity (372 mA h g~(-1), its application in LIB is limited.
