WeLion New Energy and its semi-solid-state batteries

What happened

WeLion New Energy and its semi-solid-state batteries, according to MIT Technology Review. WeLion New Energy is on a quest to make safer, better batteries. Lithium-ion batteries are commonly used to power personal devices and vehicles today.

But as the need for batteries surges, there’s a growing appetite for cells that can store more energy on a single charge. Also, in lithium-based batteries the electrolyte, which facilitates ion transfer, operates with a flammable liquid that can create a fire hazard.

Several companies, including WeLion New Energy, are working to make solid-state cells, which use a solid electrolyte instead of a liquid one. Fully solid-state cells are extremely difficult to manufacture, though.
