Research Progress in Modified Graphite Negative Electrode Materials for Lithium-Ion Batteries

Abstract

As manufacturing and technology advance quickly, more and more energy is utilized, creating a number of issues with resource scarcity and environmental damage. Electric chemistry technology has advanced quickly in recent years, with lithium-ion batteries (LIBs) standing out due to their higher working potential, high energy density, and low pollution levels. These batteries are now widely employed in industrial sectors including electronics and electric cars. Carbon-based materials are frequently employed as negative electrode materials for LIBs because of their benefits of having a large specific surface area, strong conductivity, and affordability. However, untreated graphite has drawbacks such as low capacity, unstable layered structure, and low charging and discharging platform, which can have a significant impact on the performance of batteries. By modifying graphite materials differently, these problems can be effectively solved. Therefore, this paper faced by LIBs and potential future developments is summarized in this study, along with certain modification techniques and research advancements of graphite anode materials in recent years.
