Ultrathin Sb2S3 nanosheet anodes for exceptional pseudocapacitive contribution to multi-battery charge storage

Few-layer 2D Sb2S3 (2D-SS) nanosheets are synthesized using a simple and scalable exfoliation method assisted by Li intercalation, which are employed as bifunctional anodes for both lithium ion batteries (LIBs) and sodium ion batteries (SIBs) for the first time. The 2D-SS nanosheets present a well-defined layered structure with an ultrathin thickness of 3.8 nm and a lateral size as large as several tens of micrometers, giving rise to an...
