Fast Charging Anode Materials for Lithium‐Ion Batteries: Current Status and Perspectives

TLDR

Fast charging of lithium‑ion batteries is urgently needed for electric vehicles, but traditional graphite anodes suffer from slow kinetics and lithium plating, prompting research into anode materials with rapid Li‑ion diffusion and fast reaction kinetics. This review surveys the current status of fast‑charging anode materials, outlining the key challenges, material structures, lithium‑storage mechanisms, and recent advances in morphology control, structural design, surface/interface modification, and multiphase systems, and discusses future directions. The authors analyze how morphology regulation, structure design, surface/interface modification, and multiphase system formation enhance the rate performance of various anode materials by improving Li‑ion diffusion and reaction kinetics.
