中文摘要:超级电容器作为一种新型的储能器件,其性能一直由电极材料所决定。采用简单的水热法制备了普鲁士蓝(PB)方块纳米材料,并通过原位氧化聚合法成功包覆聚吡咯(PPy),得到PB@PPy纳米复合材料。在1 mol/L的KOH电解液中对其进行电化学测试,表现出优秀的电化学性能:当电流密度为0.5 A·g^(-1)时,PB@PPy纳米复合材料的比电容为706 F·g^(-1),在5 A·g^(-1)^(-1)的电流密度下经过3000次的充放电循环测试后,比电容保持率为70.48%。所合成的PB@PPy纳米复合材料在超级电容器中有较大的应用潜力。
外文摘要:As a new type of energy storage device, the performance of the supercapacitor has always been determined by the electrode material. Prussian blue(PB) square nanomaterials were prepared by a simple hydrothermal method, and polypyrrole(PPy) was successfully coated by in-situ oxidative polymerization to obtain PB@PPy nanocomposites. It was electrochemically tested in 1 mol/L KOH electrolyte. The results show excellent electrochemical performances: the specific capacitance of PB@PPy nanocomposites is 706 F·g^(-1)at a current density of 0.5 A·g^(-1), and the specific capacitance retention rate is 70.48% after 3 000 charge-discharge cycles at a current density of 5 A·g^(-1). The synthesized PB@PPy nanocomposites have great applications potential for supercapacitor.
