Who makes semi-solid-state batteries?

The development of semi-solid-state batteries is primarily being led by Chinese companies, including CATL, one of the world's biggest battery producers, and the likes of WeLion, Qingtao Energy and Ganfeng Lithium.

Are semi-solid-state batteries a good choice?

Though semi-solid-state batteries won’t reach the energy densities and life-spans that are expected from those with solid electrolytes, they’re at an advantage in the short term because they can be made on conventional lithium-ion battery production lines.

What is a solid-state battery?

As the name suggests, solid-state batteries contain a solid electrolyte, made from materials such as ceramics. That makes them different from conventional lithium-ion batteries, which contain liquid electrolyte. This next-generation technology theoretically packs more energy into each unit of volume than lithium-ion batteries.

Are solid-state batteries the 'Holy Grail' of sustainable driving?

Solid-state batteries have long been billed as the "holy grail" of sustainable driving. As the name suggests, solid-state batteries contain a solid electrolyte, made from materials such as ceramics. That makes them different from conventional lithium-ion batteries, which contain liquid electrolyte.

Are solid-state batteries the future?

Martin, whose research areas include glassy solid electrolytes for solid-state lithium batteries and high-capacity reversible anodes for lithium batteries, believes that solid-state batteries are the future and that hybrid semi-solid batteries will likely be a transition between liquid and solid-state batteries.

When will solid-state batteries be available in Japan?

A sign is displayed outside a Toyota Motor Corp. dealership on Jan. 30, 2024 in Tokyo, Japan. Japan's Toyota, for instance, has said it is aiming to bring solid-state batteries into mass production between 2027 and 2028.
