Development of elemental technologies for greater sustainability and efficiency

  • Separator

    The unique structure of the 3DOM separator extends battery life and provides multiple forms of protection against dendrites, the main cause of battery degradation and failure, for improved reliability even in battery chemistries with high energy density. 3DOM separator technology is versatile for use in lithium ion batteries, next-generation lithium metal and solid-state batteries, and fuel cells.

  • Battery

    We are developing advanced lithium ion batteries, lithium metal batteries, and solid-state batteries designed to maximize the benefits provided by the unique 3DOM separator. We offer solutions optimized to meet the requirements of diverse mobility and stationary energy storage applications.

  • Motor

    We are developing a high-efficiency motor for a complete powertrain in combination with our advanced batteries. The motor has a Halbach arrangement magnet structure that enables high magnetic flux density and features high torque and low vibration. The use of multiple coils also improves efficiency, accuracy, and safety. The technology was adopted by the Japan Science and Technology Agency for its A-STEP Program (Adaptable and Seamless Technology Transfer Program through Target-Driven R&D).

  • Fuel Cell

    Our fuel cell technology is designed to use biomethanol as fuel, making it environmentally and logistically friendly. The fuel cell is characterized by high efficiency, limited use of platinum catalyst, and low cost, and features a 3DOM-structure electrolyte membrane and newly developed electrolyte.


Development of advanced applications for the realization of a 100% electric society

  • Land

    We are developing the world's most efficient electric powertrains and electric mobility for land transportation equipment (cars, trucks, etc.), which generates about 75% of the transport sector's CO₂ emissions.
    In addition, we are researching mobility solutions to make more efficient use of existent private vehicles, which are said to have an operating rate of less than 5%.

  • Sea

    In order to reduce CO₂ emissions from marine transport, which plays a crucial role in global logistics, the electrification of vessels has become an essential issue. We are developing core technologies, such as battery systems and motors, necessary to make the electrification of vessels a reality.

  • Air

    We are developing air mobility and transport drones, which have great potential as new means of transportation, as well as their electric powertrains.


Development of operating systems and solutions that enable overall optimization by connecting and visualizing various elements of our lives


    DI (Digital Intelligence) = AI (Artificial Intelligence) + NI (Natural Intelligence)
    We are moving from the age of creating a computer brain with AI to the age of digitizing the brain with DI. Through a deep human-like understanding of linguistic meaning based on individual experience and a digital grasp of conditions and situations, our communicator connects people to each other and to machines, with personal values at the core.
