Associate Professor Stephan Sylvest Keller from DTU Nanotech has received the prestigious consolidator grant of an amount of 2.7 mio Euro (20 mio DKK) from the European Research council for the project ““PHOENEEX” - Pyrolytic Hierarchical Organic Electrodes for sustaiNable Electrochemical Energy Systems.

The vision of PHOENEEX is to develop a miniaturised biobattery. The purpose is to produce new carbon based 3D-microelectrodes by pyrolysis of polymer microstructures.

The demand for innovative and compact solutions for the energy supply of mobile sensor units or “wearable electronics” is ever increasing.

Bio-photovoltaic cells in which bacteria are used to convert light to electrical power are promising candidates for sustainable energy conversion. Unfortunately, these systems still have a relatively low efficiency and yet cannot deliver the required power for miniaturised sensors. These are the issues whereon PHOENEEX will focus.

"We will adapt the electrodes to improve the harvest of energy - produced by light-sensitive bacteria. At the same time, we will integrate the electrodes into so-called supercapacitors, which can temporarily store the recovered energy until there is enough power for it to be used by microsensor systems, "explains Stephan Sylvest Keller.
