Improvement of Lithium Battery Anode by Three Kinds of Nanomaterials

Abstract

In today's world energy structure, the majority of the energy utilized by humans comes from fossil energy including coal, natural gas and oil. According to the current international energy forecast, oil resources will be exhausted in 40 years, natural gas resources will be used up in 60 years, and coal resources can only be used for 220 years. Therefore, people began to vigorously develop electric vehicles, in which battery is the first problem to be solved .In order to improve the performance of lithium battery, nano-materials are used as anode. Including graphene strengthening structure, improving electrochemical characteristics, carbon nanotubes improving silicon lithium batteries, and silicon nanowires improving lithium content of lithium batteries. Studying the improvement of nano-materials on the anode of lithium batteries can improve the current performance of lithium batteries, break through the current theoretical bottleneck, and provide theoretical support for the optimization of the world's energy structure,,and provide a feasible direction for improving the cycle stability, safety and other related electrochemical characteristics of lithium batteries.
