Boosting potassium-ion batteries by few-layered composite anodes prepared via solution-triggered one-step shear exfoliation
Abstract
Developing high-performance potassium-ion batteries remains a challenge. Here, the authors show that few-layered Sb2S3/carbon composite anode synthesized via simple exfoliation minimizes the volume changes during (de)intercalation of K+ ions with boosted rate performance and cyclability.
