At the Christian Doppler Laboratory for Lithium Batteries at TU Graz Michael Sternad, Martin Wilkening und Georg Hirtler (from left to right) managed to use monocrystalline silicon, which microchips consist of, directly as a battery electrode. Thus the microchip not only houses the electronics, but is at the same time an important part of a mini battery.
Electrochemists at TU Graz have managed to use monocrystalline semiconductor silicon as an active storage electrode in lithium batteries. This enables an integrated power supply to be made for microchips with a rechargeable battery. Photographic material available for download at the end of the text Small electrical gadgets, such as mobile phones, tablets or notebooks, are indispensable accompaniments of everyday life. Integrated circuits in the interiors of these devices monitor, control and regulate the most varied processes. A ubiquitous trend in microelectronics is towards the smaller, more mobile and more diverse. And this shows how important the research results published in Scientific Reports by the research team led by Michael Sternad and Martin Wilkening from the Christian Doppler Laboratory for Lithium Batteries at TU Graz's Institute for Chemistry and Technology of Materials are. The on-board power supply of a microchip could definitely extend the range of applications of microelectronics.
