2,3-Diaminophenazine@carbon felt with chemical grafting via amide bonds as an electrode in lithium-ion batteries.

Grafting organic molecules onto an insoluble matrix is an effective way to improve the electronic conductivity and insolubility in electrolyte of organic electrode materials. The active group of CN in DAP@C composites synthesized by chemical grafting of 2,3-diaminophenazine (DAP) with carbon felt through amide bonds (-CO-NH-) displays excellent electrochemical behavior.
