Scientists honored with Carl Freudenberg Prize

Shaping the technologies of the future

Which components lead to improved battery performance and a longer service life? How can improvements in production be achieved when the service life of miniaturized gears is calculated in relation to manufacturing defects? How should technical products be developed and improved to meet customer requirements? Dr. Michael Schönleber, Dr. Benjamin Häfner and Dr. Simon Klingler were recently honored for their scientific research into these three questions and presented with the Carl Freudenberg Prize by Professor Albert Albers, Head of IPEK, the Institute of Product Engineering at the Karlsruhe Institute of Technology. The jury, led by Professor Albers, paid tribute to the work of each of the three scientists. The prize is awarded every two years.

Schönleber, whose work received first place, explained, “The results of my research help to develop new materials for batteries – more quickly – and with a specific goal in mind.” The scientist, who holds a PhD, worked for some five years during his doctorate on “Methods for characterizing the low-frequency behavior of lithium-ion batteries.” Each morning he would first go to the lab to check whether his experiments were still running.  The remainder of the day would be taken up with lectures or supporting students and it wasn’t until the evening that he would be able to turn his attention again to his doctoral thesis. “Of course, I sometimes worried that I was going completely in the wrong direction – but then there’s no gain without pain – and it was often the case that I made the greatest gains in knowledge following a major crisis,” Schönleber continued. As all scientists, Schönleber also has a dream – to understand the processes inside a battery so well that ageing can be specifically prevented. “In this way, I hope I can contribute to e-mobility achieving a breakthrough and making the technology even more environmentally-friendly,” he said. When I first heard the news about having been awarded the prize, I could barely believe my ears. All the more reason to be happy. As I’ve just created a start-up with a friend, the recognition associated with the prize will help us enormously.”

“My approach is valuable for product development,” explained Klingler, whose work on, “A method for efficiently and effectively supporting continuous validation in the context of PGE product generation development,” achieved second place. “It’s about how a product can be checked again and again, so that it’s exactly what the customer needs and wants.” Klingler is delighted when he gets home in the evening and discovers that he’s won the prize. “It was a very unexpected reward for all the work I’d put in over the past five years,” he said.

“My model can be used to make the production process of important components more efficient, in order to reduce costs and achieve a higher quality,” explained Häfner whose work on, “Service life prognosis as a function of production deviations in micro-gearings,” also achieved second place. The gears examined are used in transmissions in, for example, the automotive industry, in medical technology or robotics. “New technological challenges in production have to be faced all the time. For example, e-mobility demands that new production methods are developed and put in place. It’s really exciting for me to be able to intensively work on such a challenge, and to play a part in the on-going close cooperation between business and science.”
