Plant extract works as cathode for batteriescathodelithium-ion batteriesPlant extract
Researchers say a plant extract can be turned into a highly effective, natural cathode for lithium-ion batteries.
Purpurin (above left) is extracted from madder root (center) and is chemically lithiated (right) for use as an organic cathode. The material was developed as a less expensive, easier-to-recycle alternative to cobalt oxide cathodes now used in lithium-ion batteries.
