TDK Makes Wearable Battery Breakthrough

Electronic components manufacturer TDK claims it has developed the battery material designed for use in wearable devices. The company stated the new material offers 100 times higher energy density than its conventional product.

The Japan-based firm said the material would be used in its next-generation CeraCharge solid-state battery. It states the new models will have an energy density of 1,000 watt-hours per liter, a unit used to measure a battery’s energy content in relation to its volume.

TDK noted the material will provide a significant boost to its existing mass-produced solid-state batteries due to the use of oxide-based solid electrolytes and lithium alloy anodes. The company claims the material made batteries extremely safe, and plans to use it in consumer electronics coming into direct contact with the human body.

Devices set to use the upcoming generation of batteries include smart watches, wireless earphones, and hearing aids. These are set to benefit from a smaller battery allowing more streamlined device design and longer operating time, the company indicated. The Japanese technology company makes components for a wide range of electronics including smartphones, infrastructure, and electric vehicles.
