Abstract: There is provided the use of a nitro-substituted aromatic compound of formula (I), (II), (III), or (IV) and a copolymers comprising repeat units of formula (III) and/or (IV) as an electrode material as well as the use of such compound in the manufacture of an electrode. An electrode composite material and an electrode comprising this compound are also provided. When used in metal-ion batteries, preferably Li-ion batteries, the electrode of the invention has a combination of high operating voltage (e.g. >2.0 V) and high specific capacities (e.g. >300 mAh g−1). To the best of the inventors' knowledge, some of them have the highest specific capacity, along N with high voltage, among organic electrode materials reported to date for application in alkali-ion batteries. (I), (II), (III), (IV).
