Solid-state battery – a hybrid of battery and capacitor

Solid-state battery – a hybrid of battery and capacitor


With CeraCharge, TDK has developed the world’s first solid-state battery in SMD technology. In contrast to most common battery technologies, CeraCharge works without any liquid electrolytes. by Christoph Hammerschmidt @

Similar to ceramic capacitors, the CeraCharge is based on multilayer technology and combines a high energy density in the smallest possible space with process reliability in the manufacture of multilayer components. The use of a ceramic solid as electrolyte also excludes the risk of fire, explosion or leakage of electrolyte fluid.

In the compact size EIA 1812, the battery, which can be rechargeable several dozen to 1000 times, offers a capacity of 100 µAh at a nominal voltage of 1.4 V depending on the requirements. In the short term, currents in the range of a few mA can also be drawn.

    It is odd that there is no link for more details about this new solid state surface-mounted battery. The text here does not even say its size.
