Researchers synthesize battery cathode from lignin derivatives

Green Car Congress

Milczarek and Inganäs describe how a class of organic compounds known as quinones allows the lignin derivatives to shed a proton and store this electric charge in its place. Materials for charge storage are desired from easily accessible and renewable sources. Their research appears in the 23 March issue of the journal Science.
