In a proof-of-concept study, as a step forward in the development of a fiber-shaped battery that could be integrated into garments, an international team of researchers (USA- North Carolina State University, Thailand) created a yarn-shaped cathode. They utilized the unique properties of graphene to make a yarn-shaped zinc-ion battery. They created different manganese dioxide microparticles in various shapes and sizes and embedded them in fiber made of graphene oxide. They found the shape and size of the graphene oxide and manganese dioxide materials affected its electrochemical function. When the graphene and manganese dioxide were well-mixed, they could use the fiber to create a functional battery. The rod-shaped manganese dioxide had the best performance. Although battery’s performance was low, the researchers were able to use it to power a wristwatch. According to the researchers study showed that the shape and size of the additives in the fiber affected the fiber formation process of graphene oxide… read more. TECHNICAL ARTICLE
