TDK Corporation has introduced a groundbreaking ceramic solid-state battery technology with an energy density 100 times higher than traditional models, offering 1,000 watt-hours per liter.

These new batteries are targeted for wearable devices like future Apple Watch and AirPods models.

The technology utilizes oxide-based electrolytes and lithium alloy anodes, ensuring safety for devices in contact with human skin.

Challenges remain in scaling the technology for larger applications, but TDK is moving towards mass production.

TDK aims for potential entry into the electric vehicle market in the late 2020s.

EU regulations on mobile device batteries may drive adoption of TDK's ceramic batteries, providing significant battery life improvements for devices like the Apple Watch.

CEO Noboru Saito is optimistic about transforming energy storage with this groundbreaking technology.
