由于对使用紧凑和低功率无线传感器的需求不断增加，近年来对设计具有能量收集和存储双重特性的混合电池的兴趣一直在增长。在不同的设计中，双电极混合电池更适合于低电压和低功率的电子学。使用氧化还原活性的聚乙烯醇（PVA）/聚苯胺（PANI）为基础的凝胶电解质，一个双端器件的制作和测试在这项研究中。在由碳纳米管基阴极和四种不同阳极制成的不同装置中评估凝胶电解质的性能。所有测试的阳极由涂覆有介孔TiO 2、透明TiO 2、不透明TiO 2或介孔ZrO 2的导电玻璃制成。通过循环伏安法（CV）、开路电压（OCV）和短路电流（SCC）测试了器件的性能。具有透明TiO 2涂层的所制造的装置已经显示出0.363 mF的电容，并且具有不透明TiO 2涂层的所制造的装置已经显示出244 mV的光伏电势。结果表明，进一步研究材料的纳米结构，以实现更高的能量转换效率和更大的存储电容，为未来的无线设备的应用。
Due to the increasing demand for using compact and low-power wireless sensors, the interest in designing hybrid cells with the dual properties of energy harvesting and storage has been growing in recent years. Among different designs, twoelectrode hybrid cells are more suitable for low-voltage and low-power electronics. Using a redox-active polyvinyl alcohol (PVA)/polyaniline (PANI)-based gel electrolyte, a two-terminal device was fabricated and tested in this study. The performance of the gel electrolyte was assessed in different devices made from a carbon nanotube-based cathode and four different anodes. All the tested anodes were made from a conductive glass coated with mesoporous TiO2, transparent TiO2, opaque TiO2, or mesoporous ZrO2. Cyclic voltammetry (CV), open circuit voltage (OCV), and short circuit current (SCC) were conducted to investigate the properties of the devices. The fabricated device with the transparent TiO2coating has shown a capacitance of 0.363 mF and with the opaque TiO2 coating has shown a photovoltaic potential of 244 mV. The results suggest further studies on materials nanostructure to achieve higher energy conversion efficiency and larger storage capacitances for future applications in wireless devices.
