Quantum batteries that create the future
Overview Features Comparison with secondary batteries
Quantum battery,
a new fundamental theory has been born.
Unlike all-solid-state batteries and secondary batteries, which have been the subject of much research to date,
quantum batteries are effective as large-capacity secondary batteries with a current collector layer added to the capacitor.
In the case of lithium batteries that use an electrolyte, a chemical reaction occurs when electricity is stored or released, causing one substance to change into another. This means that repeated recharging shortens the battery's lifespan, and in some cases there is a risk of fire.

In quantum batteries, the charge is stored on the surface of the electrodes by electrostatic force, and since no chemical reaction is used, there is no change in the substance. By layering quantum laminates, the surface area and the amount of electrons retained are expanded, and the amount of electricity that can be stored is dramatically increased, making it possible to quickly add and remove electricity. Quantum batteries have the characteristic of being able to be used repeatedly without deteriorating.
Features of Quantum Batteries
The possibility of a quantum 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. he 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.
