SnP0.94 nanoplates/graphene oxide composite for novel potassium-ion battery anode
Abstract
Abstract Metal phosphide based anodes for potassium-ion batteries (KIBs) have attracted increasing attention due to their high theoretical capacities and appropriate operating voltages. In this work, monodisperse SnP0.94 nanoplates are synthesized through a facile hot-injection method, followed by the fabrication of a SnP0.94 nanoplates/graphene oxide (SnP0.94@GO) composite. The results show that as-prepared SnP0.94@GO composite can serve as a novel anode for KIBs, and exhibit superior potassium storage performance.
