Abstract :Lithium-ion batteries (LIBs) are vital components in mobile devices and electric vehicles (EVs) due to their high energy density and long lifespan. However, to meet the rising demand for electrical devices, LIB energy density must be improved further. Anode materials, as a key component of lithium batteries, significantly improve overall energy density. LIBs are a widely utilized electrochemical power source in EVs and energy storage. LIBs have proven to be consistent because of their superior power density, which is directly related to the type of cathode, and extended lifespan in comparison to other types of rechargeable batteries. LIBs are developed with suitable electrolytes through a complex pathway that almost parallels advances in electrode chemistry. This article concentrated on the intercalation of alkali metal ions (Li+) into graphite, summarizing the important advances from experiments and theoretical calculations that underlie the tight host-guest relationship. This study elucidates the effect of the intercalation mechanism on the LIB on the electrode surface to achieve high-performance LIBs. Li metal ions in graphite are intercalated into monovalent and multivalent ions in layered electrode materials. This will result in a better understanding of intercalation chemistry in host materials for storage and conversion applications.
