As the important components of LIBs, cathode materials play a key role in electrochemical performance ( Nitta et al., 2015). In LIBs, lithium-based metal oxides act as a cathode and graphitic carbon acts as an anode, and the electrolyte is a liquid organic solvent containing lithium salt ( Nara et al., 2019).

Over the past decades, lithium-ion batteries (LIBs) have a wide range of applications due to their great advantages of low cost, long cycling lives, and high-energy densities, including portable electronic devices, electric vehicles, and grid energy storage ( Okubo et al., 2010 Cui et al., 2016). Finally, we summarize the challenges and perspectives of carbon-based materials on the cathode material design for LIBs. In addition, the influence of different carbon-based nanostructures, including CNT-based networks and graphene-based architectures, on the performance of cathode materials is also discussed. Then, the recent achievements and challenges of carbon-based materials in LiCoO 2, LiNi xCo yAl 1-x-yO 2, and LiFePO 4 cathode materials are summarized. The commonly used synthetic methods and recent research advances of cathode materials with carbon coatings are first represented. This feature review systematically outlines the significant advances of carbon-based materials for LIBs. Carbon-based materials are one of the most promising cathode modification materials for LIBs due to their high electrical conductivity, large surface area, and structural mechanical stability. With rapid growing demands for large reversible capacity, high safety, and long-period stability of LIBs, more explorations have been focused on the development of high-performance cathode materials in recent decades. Lithium-ion batteries (LIBs) have attracted great attention as an advanced power source and energy-storage device for years due to their high energy densities.
