EnerCera is a Li-ion rechargeable battery with NGK's original Crystal Oriented Ceramic Plate as electrodes. The Crystal Oriented Ceramic Plate is composed of just an active material and it contains no organic binder or conductive material which exists in a Li-ion battery normally but does not contribute to battery capacity. Therefore, EnerCera realizes high energy density and low internal resistance with a small and thin body and is capable of high-temperature installation. The energy density is double and the internal resistance is less than a half ompared to commercial rechargeable batteries of the same size. Therefore, EnerCera is an ultra-small/ultra-thin onboard-type high-performance battery for operating ICs, sensors and a wireless communication system which needs large current such as several 10 mA to several 100 mA. In addition, CV (Constant Voltage)-charging capability eliminates the need for a charger IC to control the charge current.
EnerCera has two types: “EnerCera Pouch,” an ultra-thin and bendable cell, 0.45 mm thick, for embedding in a card, and "EnerCera Coin," a coin type cell, 1 mm to 2 mm thick, for mounting on a circuit board. EnerCera Pouch is the world's first thin-type Li-ion battery which can be embedded by hot lamination (above 100 degree Celsius) used widely in the IC card production. The EnerCera Pouch lineup has a fast charging type, a high-capacity type and a high-power type for customers' various device designs. EnerCera Coin is the world's first SMD (surface mount devices)-type Li-ion battery which can be mounted by Solder Reflow, commonly used as an electronic component-mounting process, and it has a high discharge current property sufficient to operate devices.
