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
