Flow batteries allow for increasing energy capacity, primarily through larger tanks, without changing the electrochemical core, and they are considered relatively safe for stationary use, if not for one problem - the fear of bromine leakage.
Porous structures are at the core of many diverse applications in the energy world: space, smart buildings, solar cells, solar fuels, nuclear energy, fuel production, geothermal energy production, fuel cells and fast charging. The researchers explain in the article that proper design of these structures is an essential condition for technological, economic and environmental improvement in the energy sector.
