With the rapid prosperity of the global electric vehicle market and increasing demand for the higher user experience of portable electronics, the development of high-performance lithium-ion batteries (LIBs) with fast-charging capability has become an inevitable trend. However, the utilization of mainstream graphite anodes in LIBs presents critical technological obstacles such as capacity degradation and safety hazard during fast-charging. Herein, this review summarizes the current advancements, fundamental principles, key strategies, and challenging perspectives of graphite anodes for achieving fast-charging LIBs. Firstly, based on uncovering the lithium intercalation mechanism of graphite anodes and the enigmatic interface between graphite anodes and electrolytes, we analyze the main challenges faced by fast-charging graphite anodes. Then, we outline the key strategies for fast-charging LIBs, focusing on graphite material design and electrolyte optimization. Finally, we propose promising research directions and key perspectives for fast-charging graphite anodes, offering the inspiration for further commercialization of fast-charging LIBs.
