Honda Motor Co., Ltd. has introduced a cutting-edge demonstration production line dedicated to developing all-solid-state batteries at its research facility in Sakura City, Tochigi Prefecture, Japan. This initiative marks a pivotal step toward mass production, with the batteries slated for application in Honda’s electrified vehicles by the latter half of the 2020s. The facility is designed to replicate mass production processes and features state-of-the-art equipment to verify each stage of battery creation, from electrode material preparation to cell assembly. Construction was finalized in early 2023, with operations on the line set to begin in January 2025. The project also integrates innovative techniques, such as roll-pressing, to enhance productivity, interfacial contact in battery components, and energy efficiency, further reducing production costs.
The development of all-solid-state batteries signifies Honda’s ambition to revolutionize EV performance and affordability. Leveraging its expertise in mass production, Honda is addressing the limitations of traditional EV batteries by enhancing energy density, heat resistance, and cost efficiency. This effort aligns with Honda’s broader strategy to achieve carbon neutrality by 2050 and make electric and fuel cell vehicles 100% of its global sales by 2040. The company’s approach includes simplifying cooling structures, utilizing unique material design, and scaling production for widespread application across automobiles, motorcycles, and aircraft. According to Keiji Otsu, President of Honda R&D, these batteries represent a transformative technology poised to lead the EV era. Through its focus on technological innovation and sustainability, Honda aims to deliver unprecedented value to customers and advance global mobility.
