CeraCharge

Rechargeable solid‑state SMD battery

 Intro Pic

From simple gadgets to complex devices for the industrial IoT – they all require compact, reliable and extremely safe power supplies. In order to meet all these demands, TDK has developed CeraCharge, the world’s first rechargeable solid-state SMD battery. Based on a multilayer technology similar to the one used in Multilayer Ceramic Chip Capacitors – with no liquid electrolyte.

Powering the future with solid-state batteries

 IoT Pic

Life today would be unimaginable without batteries. We depend on accumulators that are not only based on a variety of technologies but also offer a wide range of capacities.

In all its facets, the Internet of Things will require in the future billions of special power supplies tailored to the requirements of new ultra-low-power semiconductors and sensors. These devices must function for years, independently of external power supplies, by using energy-harvesting technologies. The demands made on energy storage media are as follows: small dimensions, rechargeability, intrinsically safe, easy to assemble, low cost, and long service life. Not all of these requirements can be met simultaneously using currently available technologies.

TDK CeraCharge offers a way out of this dilemma and can be used in a wide range of applications e.g.:

  • IoT devices e.g., smart meters, programmable logic controllers (PLCs), smart home sensors, real-time clocks (RTC)
  • Bluetooth beacons (BLE)
  • Wearable devices
  • Systems for energy harvesting
