EnerCera― 0.45 mm-thin rechargeable battery for IoT tags & wearables

NGK's Product EnerCera

About EnerCera

The EnerCera battery is an ultra-thin and ultra small Li-ion rechargeable battery. A semi-solid-state battery developed using NGK’s original crystal oriented ceramic plate as electrodes, EnerCera achieves features that were difficult to incorporate together in existing Li-ion rechargeable batteries, such as high capacity, high output, high heat resistance, and long lifetime.

Main features:

  • An ultra-thin, compact power solution that delivers high heat resistance, exceptional safety and reliability, high output, and long-lasting performance.
  • Due to its low internal resistance, EnerCera batteries can store incredibly small amounts of electricity and output large amounts of power when required.
  • The ideal power source for environmental power generation (energy harvesting) and wireless power transfer (WPT).
  • For maintenance-free IoT devices that rely only on natural energy sources and which can be used repeatedly.

Key technologies:

  • Crystal oriented ceramic electrode
  • Semi-solid state battery

Lineup:

EnerCera Pouch/EnerCera Coin

Target Applications:

Wearable devices, Card-type devices, Backup power applications
