Researchers from the City University of Hong Kong and Southern University of Science and Technology have developed a new water-based, eco-friendly battery based on tofu brine.
“Compared with current aqueous battery systems … our system delivers exceptional long-term cycling stability and environmental friendliness under neutral conditions,” the team said in its paper.
The new battery uses what the team calls “organic” electrodes with neutral, non-toxic electrolytes. According to the team, the new tofu-brine-based battery is capable of 120,000+ charge cycles, and is basically saltwater-level safe.
This means it is neither acidic nor flammable. If scalable, this could prove revolutionary, especially in terms of replacing other battery tech like lithium-ion.
