Current knowledge on Na metal anode has been limited on its room-temperature or high-temperature (molten Na-S system) performances. However, the properties regarding to its low-temperature and fast-charging performances are rarely...

An all-fluoride fire extinguishant is embedded within the electrolyte via bridge solvents, enabling safe and stable sodium metal batteries.

The exhausted graphite from spent Li-ion batteries is recycled and reused as a favorable anode for Na/K-ion batteries, and the insights into structural de-/intercalation model are realized.
