Honda Motor Co., Ltd. has introduced a demonstration production line for all-solid-state batteries. This facility is located in Sakura City, Tochigi Prefecture, Japan.
The company plans to integrate these next-generation batteries into its electrified models. These batteries are expected to be used in the second half of the 2020s.
Advanced Production Facility
The demonstration line covers a total area of 27,400 square meters. It replicates all processes required for mass production of solid-state batteries.
This facility includes advanced systems for mixing materials, roll-pressing electrodes, forming cells, and assembling modules. Honda aims to begin production by January 2025.
Honda will use this line to test production technologies, optimize costs, and finalize battery cell specifications.
Revolutionary Manufacturing Process
Honda employs a unique roll-pressing technique in the production of all-solid-state batteries. This process increases the density of solid electrolyte layers and boosts performance.
The technique also enhances the contact between electrodes and electrolytes, ensuring better productivity. Streamlined assembly processes will reduce production time per battery cell.
Focus on Cost Efficiency
Honda is adopting energy-efficient systems to lower power consumption during production. Efforts are being made to simplify cooling structures and reduce indirect production costs.
The company plans to use these batteries for various mobility products. These include automobiles, motorcycles, and even aircraft.
Addressing EV Challenges and Honda’s Vision
All-solid-state batteries are known for high energy density and excellent heat resistance. These features address key EV challenges such as range, charging time, and cost.
Honda aims to improve performance and affordability by optimizing production methods. The goal is to make EVs more accessible to a broader audience.
Honda is striving for carbon neutrality across all products and operations by 2050. By 2040, the company aims for 100% of its global vehicle sales to be electric or fuel-cell-based.
Keiji Otsu, President of Honda R&D Co., Ltd., described all-solid-state batteries as a “game-changer.” He emphasized that these batteries will drive Honda’s transformation in the EV era.

Another “demo” and “concept” from the Japanese. Big promises and no delivery. Forever stuck in “just around the corner” mode; similar to their mass produced hydrogen vehicles.
On the other hand Chery Automobile from China just announced the completion of their 1 GWh production line for solid state batteries. Production and product sales will start early next year. And the roadmap Chery shared clearly shows they will double their energy/charge density within the next 3-4 years.
While the Japanese are stuck in their ‘concept and testing’ limbo, the Chinese are leaving them (and the rest of the western world) in the dust.
