USC scientists have built a new battery that might solve the electricity storage downside constraining the use of renewable energy.
The tech is a new spin on a known design that stores electricity in solutions, sorts the electrons, and releases power when it is required. So-called redox move batteries have been around a while; however, the USC researchers have built a better model based on low-cost and available materials.
Energy storage is a giant hurdle for renewable power as a result of power demand doesn’t at all times coincide when wind turbines spin or sunshine hits solar panels. The seek for a viable storage solution faces a number of challenges, which is the problem the USC scientists sought to solve.
They focused on the redox move battery because it is proven expertise and has been deployed in limited purposes so far. It makes use of fluids to store electrochemical energy, sorting electrons, and recombining by reduction and oxidation.
The crucial innovation achieved by the USC scientists involves utilizing different fluids: an iron sulfate solution and a type of acid. Iron sulfate is a byproduct of the mining sector; it’s plentiful and cheap. Anthraquinone disulfonic acid (AQDS) is an organic material already utilized in some redox flow batteries for its stability, solubility, and energy storage potential.
