Yale researchers have identified a blood molecule that could open the door to more efficient rechargeable batteries.
Currently, the efficiency of lithium-oxygen batteries is limited by lithium peroxide build-up that coats and damages the battery’s electrodes. To overcome this obstacle, the team from Yale has been experimenting with the heme molecule, which carries the oxygen in blood.
According to the researchers, the heme molecule could function as a better catalyst by dissolving into the electrolytes to work as a redux mediator, reducing the energy needed for the battery’s charging cycles. The team believes the new technology could also provide a use for the heme molecules that are usually disposed of as waste in the animal products industry.
