Study on a novel hydrion battery system

提出并研究了一种新型的以导电高分子材料为活性材料的氢离子电池体系,该电池体系正极采用聚5-硝基吲哚,负极采用聚苯胺,电池电压为1.3V。在电流密度为10A/m2下放电,质量比容量可达85mAh/g,当电流密度提高100倍后,其质量比容量仍可达72mAh/g,说明该电池具有很好的快速充放电能力。同时,我们还探讨了正极中聚5-硝基吲哚的含量及电解质硫酸溶液的浓度对电池质量比容量的影响,以期找到制备该电池的适宜的工艺。

This study is intended to develop a polyindole-based hydrion battery system, which has a high electromotive force together with a high cycle property and is capable of fast charging and discharging. The battery includes poly(5-nitroindole) as the anode active material and polyaniline as the cathode active material. 40% sulfuric acid was used as the electrolytic solution with about 1.3 V electromotive force. The battery achieves about 85~72 mAh/g at charge and discharge current densities of 10~103 A/m2. In addition, a discharge capacity at charge and discharge current density of 103 A/m2 maintains 85% of capacity relative to that at 10 A/m2. This indicates that this battery is excellent in fast charge and discharge properties. Moreover, the discarded battery will do little harm to the environment because of its free of heavy metal.
