Research Progress of Carbon-based Cathode for Lithium Ion Battery

This paper introduces the research progress of carbon-based cathode for lithium-ion batteries. Firstly, the importance of lithium-ion batteries and the key role of cathode material performance under the background of energy challenges are expounded. This paper introduces the classification of carbon-based materials, including graphite, hard carbon, soft carbon, and new nano-carbon materials. The modification mechanism of the carbon-based cathode is discussed, such as pore-forming activation, composite material construction, and heteroatom doping. The advantages and examples of each modification method are analyzed in detail, and the scheme is summarized to improve the performance of lithium-ion batteries. Finally, the prospects and challenges of carbon-based lithium-ion battery materials are discussed, which is of guiding significance for future researchr.
