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. For many applications, the TDK CeraCharge offers a way out of this dilemma. Unlike most common technologies, this one involves a solid-state rechargeable battery with no liquid electrolyte through which the lithium ions move during charging or discharging. CeraCharge is based on a multilayer technology similar to the one used in Multilayer Ceramic Chip Capacitors.
