NGK Insulators Releases Lithium-Ion Battery for IoT Devices

NGK Insulators reports that several new Internet of Things (IoT) devices have been introduced for the health-care, mobility and agriculture sectors, but the development of these devices has brought forth issues in power supply maintenance, as the majority of batteries face capacity issues—and with rechargeable batteries, charging time and battery lifespan can pose problems. Therefore, the company introduced its Coin and Pouch batteries, part of its EnerCera series of products.

The EnerCera Coin, measuring 1 to 2 millimeters in thickness, is intended for mounting on a circuit board, while the EnerCera Pouch, an ultra-thin and bendable cell, measures 0.4 to 0.45 millimeter in thickness, for embedding in a card. EnerCera Coins are made by adding a small amount of liquid electrolyte to its all-ceramic stacked monolithic body with electrodes and separator. NGK defines these batteries as "Semi-Solid State." The lithium-ion secondary batteries have an operating temperature of 85 degrees Celsius, with a lifespan of up to 10 years, suitable for IoT devices.

The EnerCera line is intended for use in energy harvesting. In addition to storing small amounts of electrical currents, it can release large currents when needed, similar to capacitors. This feature allows EnerCera to be used as a maintenance-free power supply solution in an ultra-small, ultra-thin package.

In industrial markets, one of the largest potential applications for EnerCera is as the power source for monitoring piping, or other tasks inherently difficult for humans to conduct alone. In addition, the company reports, there is the potential for process management for factories, lighting and air-conditioning management for buildings and equipment monitoring, by utilizing EnerCera with energy harvesting or a wireless power supply.
