Development of next-generation batteries
Ceramic battery that create the future
Overview Features Comparison with secondary batteries
This research is being promoted in collaboration with a national university corporation and is combining cutting-edge academic knowledge with innovative technological developments to realize dielectric materials that transcend conventional limits. This industry-academia collaboration will enable innovative applications in the semiconductor and energy fields by leveraging the world-class research infrastructure. This has made the practical application of revolutionary materials with performance superior to existing materials a reality.
Ceramic battery,
a new fundamental theory has been born.
Onlytech's solutions for the future of energy storage will revolutionize conventional battery technology. Unlike the all-solid-state batteries and general secondary batteries that have been researched to date, we are taking a completely new approach to solving the challenges of power storage.
Our next-generation dielectric Ceramic battery is the world's first step-dielectric Ceramic battery, a technology that sets a new standard for batteries in terms of safety, environmental impact, and performance.
We are creating the future of energy with this breakthrough technology.
Features of Ceramic battery
The possibility of a Ceramic battery with a continuous, microscopic thin film and a huge surface area in terms of volume ratio.
  1. The number of charge/discharge cycles is between 20,000 and 300,000 or more (lifespan of 30 years or more) and does not deteriorate even when used at 100%.
  2. Operating voltage is wide-ranging, from 24V to 1000V (lithium-ion battery:3.8V).
  3. Outstanding energy density (1,000Wh or more/1kg).
  4. Holds 3 to 10 times more capacity than lithium-ion batteries.
  5. Power density of up to 10,000W/kg.
  6. Can be manufactured using only domestic parts and materials (in Japan).
  7. Can be rapidly charged and discharged (approximately 10 times faster than general rechargeable batteries).
  8. No risk of fire or explosion due to heat generation.
  9. The chemical substances in conventional rechargeable batteries deteriorate, but our batteries do not deteriorate and have a long life.
  10. Lower cost and higher quality than existing lithium-ion batteries.
