We demonstrated an asymmetric aqueous supercapacitor made of p- and n-type conducting polymer electrodes. We used the high electron affinity (EA) n-type polymer poly(benzimidazobenzophenanthroline) (BBL) as the anode conducting material, and the low ionization potential (IP) p-type polar polythiophene p(g₄2T-T) as the cathode material. EA_BBL matches IP_p(g₄2T-T), enabling the fabrication of all-organic asymmetric p/n-supercapacitors that function in aqueous electrolytes. The devices operate in a voltage window up to 1 V, yielding areal capacitances of 90 mF cm^–2 and specific capacitances of 33 F g^–1 as well as excellent cycling stability with almost 100% capacitance retention over 10 000 cycles.

基于p型和n型导电聚合物的不对称水性超级电容器

我们展示了由p型和n型导电聚合物电极制成的不对称水性超级电容器。我们使用高电子亲和力（EA）n型聚合物聚苯并咪唑苯并菲咯啉（BBL）作为阳极导电材料，并使用低电离势（IP）p型极性聚噻吩p（g ₄ 2T-T）作为阴极材料。EA _BBL与IP _{p（g ₄ 2T-T）}匹配，从而能够制造在水性电解质中起作用的全有机不对称p / n超级电容器。这些器件在高达1 V的电压窗口内工作，产生90 mF cm ^–2的面电容和33 F g ^–1的比电容以及出色的循环稳定性，在10000次循环中几乎保持100％的电容。
