Japanese electronic parts maker TDK said on Monday it has successfully developed a material for solid-state batteries, a breakthrough expected to bring significantly higher performance to wearable devices.
Headquartered in Tokyo apple supplier explain The energy density of this small solid-state battery material is estimated to be 1,000 watt hours per liter (Wh/l), which is approximately 100 times the energy density of TDK’s traditional mass-produced solid-state batteries.
Energy density refers to the amount of energy stored in an area of space.
Solid-state batteries are seen as a potential game-changing technology because they can store more energy and charge faster than lithium-ion batteries.
TDK said this innovation can be used in a variety of devices that come into direct contact with the human body, including wireless headphones, hearing aids and smart watches.
The battery is expected to be produced using all-ceramic materials, an oxide-based solid electrolyte and a lithium alloy anode.

TDK said it aims to use its technology to replace existing tether batteries, which are small stainless steel discs that can power portable devices and comply with EU battery regulations.
Some key features of TDK’s technology include the use of oxide-based solid electrolytes, which the company says makes them “extremely safe.”
TDK says the battery’s smaller size and higher capacitance (a device’s ability to store charge) means it can contribute to smaller devices and potentially provide longer runtimes.
