Fast kinetics of graphite anodes through interface and bulk engineering: a review
摘要
Owing to their advantages such as high energy density and excellent cycle performance, lithium-ion batteries have occupied a dominant position for many years in the fields of consumer electronics, energy storage, and new energy vehicles. Graphite is the most widely commercialized anode material because of its stable layered structure, excellent electrical conductivity, and cost-effectiveness. However, its inherent limitations, notably its relatively low theoretical specific capacity (372 mAh/g) and sluggish intrinsic ion diffusion kinetics, pose significant challenges to the development of high-energy and power density battery systems. This article briefly introduces the intercalation and failure mechanisms of graphite anode materials, reviews the research progress in the bulk and surface regulation of these materials, and discusses their future development prospects.
