2D layered Sn‐based materials have attracted enormous attention due to their remarkable performance in sodium‐ion batteries. Nevertheless, this promising candidate involves a complex Na+‐storage process with multistep conversion‐alloying reactions, which induces the uneven dispersion of heterogeneous intermediate accompanied by severe agglomeration of metallic Sn0, inescapably resulting in poor reaction...
Regulating nanocrystal composition with multiphase compounds is considered an efficient approach to enhance electrochemical performance and structure stability. Nevertheless, the thorough understanding of significant reaction mechanisms and insight into the reason of enhanced performance is still urgent. In this work, the bimetallic sulfide Bi2S3/MoS2 heterogeneous with abundant phase boundaries is...
Molybdenum ditelluride nanosheets encapsulated in few‐layer graphene (MoTe2/FLG) are synthesized by a simple heating method using Te and Mo powder and subsequent ball milling with graphite. The as‐prepared MoTe2/FLG nanocomposites as anode materials for lithium‐ion batteries exhibit excellent electrochemical performance with a highly reversible capacity of 596.5 mAh g−1 at 100 mA g−1, a high rate...
