Days numbered for 'risky' lithium-ion batteries, scientists say, after fast-charging breakthrough in sodium-ion alternative
Summary
Live Science reports a sodium-ion battery breakthrough from Tokyo University of Science using a carbon-based HC/Al2O3 electrode to boost energy density and fast charging, potentially matching Li-ion performance with improved safety and lower cost. If scalable, Na-ion could enable rapid charging in grid storage and EVs, reducing fire risk compared with Li-ion.
