Customer needs/background Customer needs/background

Hybrid technology using an internal combustion engine (ICE) and an electric motor has begun to spread in order to reduce CO2 emissions.
Among these, unprecedented high input/output characteristics were required for heavy/special-purpose vehicles that transport heavy loads and for operation in the high speed range of motorsports. This led to the development of "ultra-high input/output lithium-ion batteries" that can handle high instantaneous power (power drive) and rapid deceleration (regenerative braking).

  • Case 1: High input/output and operation under low temperature environment
  • Case 2: High input/output and high reliability, operation with extreme performance (high temperature environment)

Execution details

  • Verification of electrode recipe from material development (high C-rate input/output characteristics, improvement of characteristics in low and high temperature range)
  • Establishment of thin coating process to achieve high input/output characteristics
  • Start-up and operation of large pouch cell production line
  • Improvement of reliability and acquisition of JISQ9100 quality standard certification

Battery type

  • Pouch Cells

    Pouch cells

Application examples

  • Motor Sports
  • Heavy Machinery, Special Vehicles
