Whether used for power supply or in electric cars, current battery systems are based on a series of interconnected individual cells, which has certain disadvantages in terms of efficiency and manufacturing. Bipolar battery setups, in contrast, comprise compact stacks of individual cells. A new type of flexible and extremely thin bipolar plate allows batteries to be manufactured cost effectively. At the Hannover Messe Preview on January 24, 2019 (Hall 19) and the Hannover Messe itself from April 1 to 5, 2019 (Hall 2, Booth C22), researchers from the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT will be presenting the development of this technology.
