    Abstract A new redox-active family of aromatic dicyanides was developed as organic electrodes in rechargeable batteries. The detailed electronic properties of two primary representatives of 1,4-dicyanobenzene (DCB) and 9,10-dicyanoanthracene (DCA) were studied. It is discovered that, as compared with DCB, the large aromatic π conjugation in DCA leads to better electron conductivity and more stable reduced states of DCA − and DCA 2− . The Li-ion batteries with DCA electrode are shown to have highly reversible operations. Highlights A new family of aromatic dicyanides was developed as the organic electrodes. 1,4-Dicyanobenzene (DCB) and 9.10-dicyanoanthracene (DCA) were studied. DCA exhibits more stable reduced states and superior electronic conductivity. DCA achieves reversible and step-by-step, two-electron process. Graphical abstract [DISPLAY OMISSION]
