The application of graphene material in the negative electrode of lithium battery

Abstract

With the development of science and technology, the massive consumption of traditional fossil fuels not only brings serious environmental pollution but also causes an energy crisis. As an indispensable new energy in today’s world, Lithium batteries have many advantages that other types of batteries do not have, such as high energy density, long life, low self-discharge rate advantages, green and environmental protection, etc., and widely used in various fields, such as automotive, medical, aerospace and so on. However, the drawbacks such as low specific capacity and high side reaction of graphite material in traditional lithium batteries limit the application of lithium batteries. Graphene, as a two-dimensional material composed of carbon atoms in a single layer thickness, possesses the advantages of huge surface area, high strength and hardness, good electrical and thermal conductivity, flexibility, and transparency, and has great potential for application in lithium batteries. In this paper, for graphene as the anode material of lithium batteries, its effects on the performance of lithium batteries, including cycling performance, charge/discharge rate, and energy density, are discussed respectively. In addition, this paper also summarizes the latest progress on the application of graphene anode materials in lithium batteries.
