Honda has introduced an experimental production line for solid-state batteries, which are being independently developed for mass production at the Honda R&D research and development unit.
By conducting technical checks to establish a mass production process on the experimental testing or demonstration line, Honda will determine the basic specifications of the battery cells with the aim of starting to implement solid-state batteries in all electrified models that will hit the market in the second half of this decade.
The experimental line to replicate the necessary process for mass production covers a total area of 27,400 m² and is equipped with facilities and equipment that allow for the verification of each process during production. Honda has also announced plans to begin production of batteries still in the testing phase in January 2025 and will analyze the mass production technologies and costs for each process while developing the specifications for the battery cells.
“Solid-state batteries are an innovative technology that will bring a significant change in this era of electrification. Replacing the engines that have supported automotive advancements to date, batteries will be the key factor in electrification”, said Keiji Otsu, president of Honda R&D. “We believe that the advancement of batteries will be a driving force in Honda’s transformation. We are now looking forward to the start of operations at our solid-state battery production test line, and we can say that we have reached an important milestone for Honda and for Japan”, concluded the same official.
It is worth noting that solid-state batteries have a higher energy density, approximately twice that of conventional lithium-ion batteries, significantly shorter charging times due to superior charge and discharge performance, and lower costs due to the use of less expensive materials.
