摘要：

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 pi 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. (C) 2016 Elsevier B.V. All rights reserved.
