Chip-type ceramic secondary batteries, “EnerCera®”
EnerCera is an ultra-compact, ultra-thin lithium-ion rechargeable battery ideal for power sources for a range of IoT devices such as tiny wireless sensor modules and IC cards. Because it is a semi-solid battery using NGK’s proprietary crystal-oriented ceramic plate for electrodes, it is highly heat resistant and can supply large current.
