ASSB's All solid state batteries supposedly from a safety perspective are in the future. Here is an excerpt from an article concerning storage technology:
"The ASSB technology is still in its very early stages today,” said Wood Mackenzie energy storage analyst Mitalee Gupta in an email. “It is still a few years until these batteries become commercially viable.”
In terms of the transportation market, "you will not see solid-state widely deployed until probably the middle part of this decade," acknowledged Solid Power's Campbell.
James Frith, head of energy storage at the analyst firm BloombergNEF, said that sometime around 2025 is a realistic timeframe for the widespread commercialization of ASSBs. That's not terribly far off in energy technology terms. "It’s fair to say the U.S. has a lot of startups that are working on this,” Frith said.
While the technology continues to march forward, a growing ecosystem is emerging to support the future ASSB industry. Michigan-based Coretec Group recently announced a manufacturing partnership with chemical giant Evonik Industries to supply cyclohexasilane that could be used for silicon nanoparticle anodes in ASSBs."
