Integrated power sources
Batteries, with inherent limited capacity, have dominated the power supply of small devices for decades. However, despite the fast evolution in the field, the energy gap between the capacity of the current battery technology and the power requirements is increasing year by year. This energy divergence brings a great challenge on portable generation that opens new opportunities for technologies beyond Li-ion. In this new scenario, a major breakthrough on the miniaturization of uninterrupted and efficient generators is crucial. In the Nanoionics and Solid State Energy Conversion Devices group, we develop new concepts in portable power sources based on different technologies, including micro solid oxide fuel cells, all solid-state microbatteries, thermoelectric power generators and more. We aim to break the traditional operating limitations of these devices and, ultimately, integrate them into silicon technology for power-on-chip concepts.
