CATL, the world’s largest battery maker, has signed a three-year deal with energy storage integrator HyperStrong for 60 GWh — the largest sodium-ion battery order ever placed. The deal marks what CATL claims is proof it has “overcome the challenges of the entire sodium-ion battery mass production chain”. And the race is on to replace lithium-ion batteries for, among other things, electric vehicles.

Researchers have developed a new solid-state lithium-sulphur battery that boosts the range of electric vehicles.
