Researchers in Hong Kong and China have developed a new form of battery that is more eco-friendly and longer lasting than lithium ion batteries – and it runs on tofu brine. The new water battery is still in research phases, but if the technology proves to be scalable enough to hit commercial markets, it could be a game-changer for the energy and tech sectors. “Compared with current aqueous battery systems … our system delivers exceptional long-term cycling stability and environmental friendliness under neutral conditions,”…
