Sodium-ion Batteries Show Desalination Potential
Researchers at the University of Surrey have discovered a method to enhance the performance of sodium-ion batteries by retaining water within a key material.
This breakthrough, published in the Journal of Materials Chemistry A, could lead to greener energy storage and desalination. Sodium is abundant and widely available, unlike lithium-ion batteries which rely on costly and environmentally damaging materials.
- Sodium vanadium oxide is a material typically heat-treated to remove water.
- Retaining water forms a nanostructured sodium vanadate hydrate (NVOH), enhancing performance.
The breakthrough could pave the way for greener energy storage and even desalination.
