Flavin derived from vitamin B2 operates as the cathode in the new battery, which is the part where energy is stored when the battery is connected to an electronic device. Looking to nature for solutions, a design approach called biomimicry made a lot of sense to the research team as they sought to build a better battery. “We’ve been looking to nature for a while to find complex molecules for use in a number of consumer electronics applications,” said Dwight Seferos, an associate professor in the university’s Department of Chemistry and Canada Research Chair in Polymer Nanotechnology.

The result is an environmentally friendly battery that is also easier to make than typical lithium ion batteries. “When you take something made by nature that is already complex, you end up spending less time making new material,” Seferos added.
