TU Chemnitz: Researchers have developed a battery the size of a grain of salt

Researchers at Chemnitz University of Technology have developed what they say is the world’s smallest battery. The European Union announced on Saturday that the prototype was smaller than a grain of salt. The battery can be used in microelectronic devices such as sensors used in the body. Also involved in the development were researchers from the Leibniz Institute for Solid State and Materials Research in Dresden and the Changchun Institute of Applied Chemistry.

The trend towards miniaturization continues in computers and therefore also in devices such as micro-sensors. In extreme cases, computers and batteries in the millimeter range will be needed. According to TU, its development has so far been slowed down, among other things, by the difference in size between the microelectronics and the required battery. With their prototype, the researchers will now show how applications can be implemented in the millimeter range.

“Our results show an encouraging performance for energy storage on the sub-square millimeter scale,” said Minchin Zhu of the research group. According to his colleague Oliver J. Schmidt, there is still huge potential to improve this technology, so that “significantly more powerful micro-accumulators can be expected in the future”.
