Bi‐Induced Few‐Layered Graphite Frameworks as Efficient Interfacial Transitions Toward Ultrafast Potassium Storage

Abstract Bismuth is a promising anode material for potassium‐ion batteries due to its green, non‐toxic and high theoretical capacity (384 mAh g−1). However, the sluggish reaction kinetics and excessive volume expansion during cycling limit its practical application. Herein, Bi‐induced few‐layered gr...
