New electrolyte design extends life of sodium-ion batteries

Researchers have engineered a specialized electrolyte that protects both ends of sodium-ion batteries from corrosion, extending their operational lifespan. The breakthrough could reduce battery replacement costs and accelerate adoption of sodium-ion technology as a cheaper alternative to lithium in grid storage and electric vehicles.
