Can Sodium-Ion Batteries Replace Trusty Lithium-Ion Ones?
Sodium-ion batteries are a potential replacement for lithium batteries, but different anodes are needed for the same level of performance. Amorphous carbon is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties. In Applied Physics Reviews, researchers describe how they applied basic physical concepts of atomic scale to build high-performance anodes for sodium-ion batteries.
