Research progress of carbon nanomaterials for lithium-ion battery anodes

Abstract

Lithium-ion batteries (LIBs), one of the most promising energy storage methods, have been widely used in portable electronic devices due to their excellent performance, including no memory effect, great safety performance, and high energy density. The performance of the negative electrode, an essential component of LIBs, has a significant impact on the metrics of the battery as a whole. However, LIBs built with traditional electrode materials have limited durability, inadequate energy and power densities, and high prices. The discovery of carbon nanoparticles enables the design of innovative energy storage materials suitable for LIBs. Its large specific surface area, short diffusion distance, high conductivity, and strong ion conductivity are just a few of the numerous distinguishing characteristics that make it a revolutionary form of carbon material. It has a wide range of application possibilities thanks to LIBs with high reversible capacity, high power density, prolonged cycle stability, and superior safety. The most recent developments in one-, two-, and three-dimensional carbon nanomaterials are reviewed in this article, along with their uses in LIBs. The difficulties and potential benefits of creating high-performance LIBs in the future utilizing carbon nanomaterials were highlighted.
