In Mg/DNP cell, 2,4?dinitrophenol underwent multi?electron transfers of up to 12 during discharge, and hence, gave high specific energy (up to 2?Ah/g) in comparison with conventional inorganic battery depolarizers such as MnO?2,HgO, CuO and AgO.

• Mg/DNP(2,4 二硝基苯酚)电池可发生12个电子的多电子转移,因而与无机电极材料如MnO2、HgO、CuO和AgO相比,其能量密度很高(高达2Ah/g)。
