Researchers have synthesized an inexpensive electrolytefor a water flow battery with redox potential, which retains 99.98% of its capacity during a working cycle and does not lose it during idle time.
This type of battery is considered promising, as it is optimally suited for storing energy fromsolar panels and wind turbines due to their low cost of use, easy scalability and environmental friendliness.The disadvantage of existing electrolytes is their low energy capacity and loss of charge over time.
RecentlyScientists from South China University of Technology have developed a new molecular compound based on the stable radical TEMPO, which easily changesits oxidation state and can store quite a lot of energy. high hydrophobic properties, the team modified it with viologen.
Superior TEMPO is highly soluble in water,is also chemically active and easily takes electrons from other atoms, changing its oxidation number. Tests in a flow-through battery have shown that the synthesized electrolyte loses only 0.02% of its capacity per cycle, so the battery can hold almost all of the stored energy when not in use.
Recall that earlier this year, researchers created a magnesium-based paste that can store 10 times more energy than a modern lithium-ion battery.
