Honda all-solid-state battery video

Honda Motor Co., Ltd. has unveiled the demonstration production line for all-solid-state batteries, which are being developed independently by Honda for mass production at the site located at Honda R&D Co., Ltd. In Sakura City, Tochigi Prefecture, Japan.

When conducting technical verification to establish a mass production process on the demonstration line, Honda will determine the basic specifications of the battery cells, with an aim to begin applying its all-solid-state batteries to the electrified models introduced to market in the second half of the 2020s.

Honda built the demonstration line to replicate the processes required for mass production. It has a total floor area of approximately 27,400 m2 (295,000 ft2) and is equipped with facilities and equipment that enable verification of each production process. This includes weighing and mixing of electrode materials, coating and roll pressing of electrode assembly and the formation of cells, and assembly of the module.

The construction of the facility was completed in the spring, with almost all key equipment necessary for verification now installed. Honda is planning to begin battery production on this demonstration line in January 2025 and will conduct verification of mass production technologies and costs for each process, while also developing battery cell specifications.

By increasing cost competitiveness of its all-solid-state batteries through the adoption of a highly efficient production process and by expanding application of the batteries to a wide range of Honda mobility products, including automobiles, motorcycles and aircraft, Honda aims to further reduce battery costs via economies of scale and expand the joy of mobility.
