The abundant natural resources and low cost benefits of zinc-ion batteries (ZIBs) and potassium-ion batteries (KIBs) offer a better alternative to lithium-ion batteries (LIBs). Nevertheless, large radius of K+ and...

Copper tetrathiovanadate (Cu3VS4) nanoparticles uniformly loaded in carbon nanofibers (CVS/CNF) are designed as a novel anode for potassium-ion batteries through electrospinning and subsequent carbonization/sulfidation treatment.

Metal phosphides are of great interest in sodium-ion batteries due to their high capacity in theory and suitable redox potential. However, the large bulk expansion and sluggish diffusion kinetics greatly...
