Solid state lithium battery heads for commercialisation
Hitachi Zosen in Japan has developed a prototype solid-state lithium-ion battery that it intends to commercialise over the next two years.

“We can offer solid-state lithium-ion batteries that are on par with the liquid type in performance even now,” said Takashi Tanisho, president of Hitachi Zosen, in reports. Solid-state batteries are more durable and have better temperature performance.

It has shipped samples of the battery to potential customers in the aerospace and automobile industries and plans to commercialise the technology in small cells by 2020, working with a local battery maker.

Hitachi Zosen has also been working on the technology for cars and has shipped samples to Honda’s research arm. “There are many companies working on solid-state batteries,” Tanisho said. “We need to work hard on how to reduce cost while keeping our lead in quality. Costs of solid state batteries haven’t reached the level competitive with the conventional lithium-ion batteries as they are hardly available in the market,” he said. “We plan to start with small-size batteries for special purposes as we expect they’d be acceptable even if they are a bit more expensive.”
