In 2008, a dedicated battery research department was developed to advance electrified transportation. In the spirit of kaizen (continuous improvement), this department is working to develop the next generation battery – beyond lithium. Solid or metal-air batteries are just two examples of battery technologies under development. Solid batteries replace the electrolytic solution in lithium-ion batteries with a solid. This solid material allows for high-density packaging and contains no flammable materials. Metal-air batteries capture a reaction between metal solution precipitation and oxygen and provide extremely high energy capacity. The battery research department is also working to develop the Toyota Sakichi battery, a high-density, quick charging and highly durable battery.
