Submission + - Cheaper Flow Batteries Using Vitamins Discovered (natureworldnews.com)
William Robinson writes: Scientists from Harvard University have discovered how to create flow batteries using organic molecules inspired by vitamin B2, which helps store energy from food in the body. With a few tweaks to the original B2 molecule, the scientists discovered a new group of organic molecules that make good candidates for alkaline flow batteries. The result of the discovery was a redox flow battery that demonstrates an open-circuit voltage approaching 1.2V, with a current efficiency of 99.7 percent and a capacity retention over 99.98 percent per cycle.
