NGK EnerCera Pouch Bendable Li-ion Rechargeable Battery Evaluation Board

NGK’s EnerCera Pouch Li-ion rechargeable batteries exhibit double the energy density and less than half the internal resistance of other similarly sized commercial alternatives. The 0.45 mm thickness enables EnerCera Pouch batteries to be used in curved installations, and the device is also the world’s first thin-type Li-ion battery which can be embedded by hot lamination (>100°C), a process used widely in smart card production. Conforming to the ISO 14443-1 standard, these devices show no deterioration after bending and torsion tests, making them a perfect power source for wearables, security tags with wireless tracking, tire pressure sensors, and more. CV charging of all devices allows for elimination of a charging IC in final integration.
