Storage of renewable energy an essential building block in the urgent transfer to a CO2-neutral society. Energy-dense and mobile lithium-ion batteries (LiBs) widely used in the transport sector can find a second life as stationary energy storage units after retiring from electric vehicles. For this, developing diagnostics for the remaining lifetime and performance of the LiBs is crucial. Redox flow batteries (RFB) are a promising technology for stationary energy storages due to their scalability and promising price development. In use, batteries undergo changes due to the degradation of the components involving gas evolution and loss of performance. OhDaBaGS project aims to employ chemical gas sensors as flexible analytical tools gather novel battery data that can promote sustainable energy storage. Increased understanding can lead to prevent unnecessarily fast aging, to aid development of the 2nd life applications of LiBs and to accelerate development of RFBs.
