Achieving climate neutrality within the next 20 years necessitates an innovation boost for the development of highly efficient, scalable, low-cost, and sustainably produced energy technologies. Polymer materials play a central role in this process. HIPOLE deeply integrates and expands world-class expertise in polymer chemistry, materials science, high-throughput experimentation and artificial intelligence with complementary expertise in inorganic/hybrid materials, scalable devices, and advanced characterization.
You have the chance to support our young Helmholtz Institute as a technician (m/f/d) with your ideas and expertise. Your responsibilities include the assembly and characterization of polymer-based batteries (such as polymer redox-flow batteries or printable thin-film batteries), using our institute’s state-of-the-art equipment and advanced technologies.
