Low-cost, easily synthesized, and high energy/power density embedded stable supercapacitive electrodes are the demands for today's renewable and green energy dependent generation. In search of that, BiS:PbS solid solution in thin film form has been synthesized by modest successive ionic layer adsorption and reaction (SILAR) method and characterized by XRD, FESEM, and HRTEM. Formation of solid solution in the form of nanoparticles gilded thin film exposes sufficient electroactive cavities for electroactive ions to incorporate. The composite exhibited excellent specific capacitance of 402.4F/g at current density of 1mA/cm with modest charge-discharge cycles. In terms of energy storage, it exhibited maximum specific power of 20.1Wh/kg with accepting specific power of 1.2kW/kg. The combination of two nanoparticles in nanocomposites thin film supplies new tactic for energy storage applications.
低成本、易合成、高能量/功率密度嵌入式稳定超级电容器电极是当今可再生和绿色能源依赖型发电的需求。为了满足这一需求，通过适度的连续离子层吸附和反应（SILAR）方法合成了 BiS:PbS 固溶体薄膜，并通过 XRD、FESEM 和 HRTEM 进行了表征。纳米粒子镀金薄膜形式的固溶体的形成暴露了足够的电活性腔，供电活性离子进入。该复合材料在 1mA/cm 的电流密度下表现出卓越的比电容，为 402.4F/g，且具有适度的充放电循环。在储能方面，它表现出最大的比功率为 20.1Wh/kg，可接受的比功率为 1.2kW/kg。两种纳米粒子在纳米复合材料薄膜中的结合为能量存储应用提供了新策略。
