Hyundai may unveil its first solid-state battery, called the ‘dream battery’, next month, with longer range and faster charging compared to similarly-sized lithium-ion batteries, Autocar writes, citing an ET News report.
March 9 is set to see the Korean carmaker open its new Uiwang research centre in Gyeonggi, where the new batteries will be tested on a pilot production line ahead of targeted mass production in 2030. A prototype vehicle with this battery is expected to begin testing this year.
Solid-state batteries are widely tipped to be the next big thing for EVs. A traditional lithium-ion battery uses a liquid electrolyte to shuttle charge-carrying ions between the anode and cathode, but in a solid-state battery, the liquid is replaced by a solid block made of either polymer, oxides or sulfides.
Besides being lighter, more thermally-stable and more energy-dense, the solid block is less reactive than the liquid, so it’s a lot less likely to ignite if punctured or heated. It can also move electrons much faster, improving charging speeds.
The catch? Cost, raw material sourcing and mass manufacturing remain challenges. Battery companies are also exploring semi-solid state packs with a gel-like electrolyte to fast-track the process.
Other carmakers exploring solid-state battery tech include Toyota, Honda, Nissan, Mercedes-Benz, BMW, Ford, Nio, MG and VinFast.

Sadly targeted mass-production on 2030.
I have a feeling by them China cars already swarming with solid state batteries.
