Disordered polyacenes were prepared from poly(styrene‐co‐divinylbenzene). The structures and electrochemical properties of these samples were studied. The result shows that the crosslinking unit of divinylbenzene in copolymer is beneficial to the charge capacity of the resultant polyacene. The change capacity of polyacene increases with the increase of the content of divinylbenzene (DVB), and finally surpasses the theoretical capacity of graphite (372 mA hr/g) when the content of DVB goes up to 5 wt%. Moreover, the charge curves have a potential plateau at approximately 1 V v. Li/Li + , and the increase of charge capacity mainly results from the lengthening of this plateau.
