Toyota Industries Establishes On-Board Battery Production Line at New Ishihama Plant, Increasing Production of Bipolar Nickel-Hydrogen Batteries for Hybrid Vehicles


Toyota Industries establishes on-board battery production line at its new Ishihama plant, increasing production of bipolar nickel-hydrogen batteries for hybrid vehicles


Toyota Industries Corporation (Chairman: Akira Onishi) has established its new plant in Ishihama. The plant will begin production of bipolar nickel-hydrogen batteries for hybrid vehicles in October 2022. The new plant is expected to operate at a production capacity of 20,000 units per month and, together with the Kyowa plant (Obu-shi, Aichi) which started battery production in May 2021, this will bring the total capacity to 40,000 units per month.

Toyota Industries developed its bipolar nickel-hydrogen battery jointly with Toyota Motor Corporation and was used for the first time in the world as an electric propulsion battery for the Toyota Aqua electrified vehicles, launched in July 2021.
In this innovative battery, a cathode is applied on one side of a metal component called the current collector and an anode on the other. Several of these structures, called “bipolar electrodes”, are stacked to form a battery. By having the cathode and anode together in the current collector, batteries can be made smaller as they require fewer parts. Additionally, the wider electrical path and simple structure reduce resistance inside the battery, allowing large currents to flow quickly. This means they can produce higher outputs compared to conventional nickel-metal hydride batteries.

The bipolar nickel-hydrogen battery, which offers both superior driving performance and environmental performance, is expected to be used in the Lexus RX unveiled in June 2022 and the Toyota Crown unveiled in July. The Ishihama and Kyowa plants are ready to handle future increases in demand.
To contribute to the expansion and diffusion of electrified vehicles and to work towards carbon neutrality, Toyota Industries is working both on a stable supply and on improving its range of batteries so that they can be used in a range electrified vehicles.
