Sodium-ion batteries (SIBs) are promising candidates for large-scale energy storage
systems due to the abundance and wide distribution of sodium resources. Various solutions
have been successfully applied to revolve the large-ion-size-induced battery issues at the
mid-to-low current density range. However, the fast-charging properties of SIBs are still in
high demand to accommodate the increasing energy needs at large to grid scales. Herein, a
core–shell Co2VO4/carbon composite anode is designed to tackle the fast-charging …
