NGK Insulators, Ltd. products
Energy storage system
NGK - NAS Batteries
The world`s first large-capacity battery energy storage system and a major leap forward in the ability to provide a stable supply of renewable energy. A product of NGK`s proprietary advanced ceramic technologies, the NAS battery was the world`s first commercialized battery system capable of megawatt-level electric power storage. The NAS battery system boasts an array of superior features, including large capacity, high energy density, and long service life, thus enabling a high output of electric power for long periods of time.
Insulators - Porcelain Insulators
NGK - Suspension Insulators
Insulators are essential to the safe and stable distribution of electricity generated at power plants. Suspension insulators support transmission lines on steel towers, isolating the lines from the tower. They play a key role in the safe supply of electricity. Based on the transmission voltage and usage environment, suspension insulators are used in configurations of two or more.
Beryllium Copper Products
NGK - Beryllium Copper Strip (Strip, Plate, Rod and Wire forms)
Widely used for contact springs, these core NGK products, available as strips, plates, rods, or wire, offer an ideal combination of properties such as tensile strength, electrical conductivity, fatigue strength, thermal stability, bending formability, and corrosion resistance.

NGK - Ultra-Thin and Compact Lithium-ion Rechargeable Battery
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.
