Götz Langer holds PhD on physical chemistry on in situ interface spectroscopy of electrochemical active interfaces (SOFC). He is member of Hoppecke R&D team since 1999. Development includes process engineering issues of LAB production as well as layout, testing and research on LAB. The team has responsibility on development for the whole international company. Since 2022 he is head of the LAB developing team.
Pure lead batteries exhibit resilience in operation over a wide range of temperatures and are therefore suitable for use without the need of any cost intensive air conditioning. Their capability to be inserted in circular systems with high recycling rates makes them particularly attractive for the use in less developed regions, unlike their lithium-based counterparts. This low enviromental footprint for pure lead storage was considered a key benefit for the Horizon Europe project LoCEL-H2, which focuses on providing off-grid energy supply to microgrids in remote areas. To simulate real-world operating conditions, various Partial State-of-Charge (PSOC) and Full State-of-Charge (FSOC) tests were selected from existing or newly developed standards. Optimization of cycle life within these tests included battery design, novel NAM additives, as well as key physical and chemical properties of AGM and PAM. Preliminary findings from these simulations will be presented, emphasizing the correlation between battery characteristics and their impact in cycle life. Based on these preliminary results, it can be concluded that pure lead VRLA AGM batteries are a viable option for low-maintenance renewable energy storage.
