Honda on Thursday unveiled what it calls an illustration manufacturing line for solid-state batteries, with goals to commercialize the know-how later this decade.
Situated in Sakura Metropolis, in Japan’s Tochigi Prefecture, the 295,000-square-foot facility is meant to ascertain the method for eventual mass manufacturing, in addition to decide prices and a few ultimate cell specs, Honda mentioned.
Development was accomplished this previous spring, and all essential gear has now been put in, in accordance with the automaker. Honda plans to begin making cells in January 2025. That is virtually a yr later than the spring 2024 goal date Honda executives talked about when first publicly discussing the demonstration plant in 2022.

Honda mentioned the manufacturing course of it plans to make use of relies on that of liquid-electrolyte lithium-ion cells, albeit with a roll-pressing step designed to extend the density of stable electrolyte layers that is distinctive to solid-state cells. This additionally will increase the diploma of interfacial contact between by the electrolyte and electrodes, in accordance with Honda.
The automaker additionally claims to have consolidated or accelerated a number of different components of the manufacturing course of, together with bonding the optimistic and unfavourable electrodes, and hopes to chop different related prices, together with by reducing vitality consumption.

Honda goals to begin mass manufacturing of solid-state batteries within the second half of the 2020s, to be used “not solely in cars, however bikes and plane.” With this wider array of purposes, Honda hopes to attain affordable economies of scale to make solid-state batteries financially viable.
Honda has been discussing solid-state batteries since at the least 2021, on the time additionally saying that they’d arrive later within the decade. Honda CEO Toshihiro Mibe advised Inexperienced Automotive Reviews earlier this yr that solid-state batteries could allow a small inexpensive EV by 2030 because of decrease battery prices and better potential vary than present cell chemistries.
