Imagine a world where batteries last longer, charge faster, and cost far less—this is now within reach thanks to a remarkable breakthrough in the UK. Researchers at the University of Surrey have demonstrated that leaving water inside sodium vanadium oxide during manufacturing actually boosts performance enormously. Instead of seeing water as a problem, they revealed that this 'wet' method produces batteries capable of storing nearly twice the energy, withstanding over 400 cycles without deterioration. Such advancements make sodium batteries a compelling alternative to lithium, especially because sodium is plentiful and inexpensive. This isn’t just incremental progress; it’s a game-changer—potentially democratizing renewable energy access worldwide and significantly lowering costs.
