<![CDATA[Electrical energy plays an important role in human life and has become a major necessity for daily activities. One of the most commonly used sources of electrical energy is batteries, which are known as flexible energy sources because they can be utilized in various places and situations. However, batteries contain various hazardous chemicals, such as mercury, manganese, lead, nickel, lithium, and cadmium. Renewable energy and environmentally friendly storage technologies are urgently needed to reduce environmental impacts. This study aimed to determine the best ratio of carrageenan and PVA based on the performance of a carrageenan-PVA membrane as an organic anode in paper battery applications. The methods used included membrane preparation with varying ratios of carrageenan and PVA, membrane characteristics, air absorption, functional group analysis, tensile strength, proton conductivity, and electrical properties of paper batteries. The results of the study showed that the membrane with a ratio of 3:1 gave the best results, with the highest proton conductivity of 9.310-6 S/cm, air absorption of 93.91%, the highest electric current of 0.008±0.001 mA, the highest electric voltage of 0.24±0.02 V and the highest electric power of 0.0019±0.0004 mW. The FTIR spectrum of the carrageenan-PVA membrane showed no chemical reaction or the formation of new groups. Carrageenan-PVA has the potential to be an environmentally friendly, flexible battery material.]]>
