In a new study, North Carolina State University researchers made a cathode, or the positive end of a battery, in the shape of a thread-like fiber. The researchers were then able to use the fiber to create a zinc-ion battery prototype that could power a wrist watch.<\/p>\n\n\n

Published in the journal ACS Applied Materials and Interface<\/em><\/a>s,<\/em> the proof-of-concept study is a step forward in the development of a fiber-shaped battery that could ultimately be integrated into garments.<\/p>\n\n\n

\u201cUltimately, we want to make a yarn-shaped battery, so we could put it in a real garment, and preferably hide it,\u201d said the study\u2019s corresponding author Wei Gao<\/a>, associate professor of textile engineering, chemistry and science at NC State. \u201cIn this study, we created a yarn-shaped cathode. Our findings were pretty promising for such a short strip of fiber, and we hope to continue this work to improve the performance, safety, and mechanical properties of our designs.\u201d<\/p>\n\n\n

To create the cathode, the researchers utilized the unique properties of graphene \u2013 a strong material with a high surface area and good conductivity – to make a yarn-shaped zinc-ion battery.<\/p>\n\n\n

In their study, the researchers created different manganese dioxide microparticles in various shapes and sizes. Then, they used a solution-spinning process to form a fiber made of graphene oxide, with manganese dioxide particles embedded within. They studied the electrochemical and other properties of the fibers.<\/p>\n\n\n

\u201cSince we are trying to make a fiber-shaped zinc-ion battery, we care not only about the battery performance, but also about the mechanical properties \u2013 we need the fiber to be strong, and also flexible,\u201d Gao said.<\/p>\n\n\n

Researchers found the shape of the graphene oxide and manganese dioxide materials that they used to make the cathode affected its electrochemical function. Specifically, they found the shorter, rod-shaped manganese dioxide components mixed homogeneously with the graphene, allowing researchers to make a fiber that could operate as a functional battery prototype. Comparatively, they found that when the manganese dioxide had a \u201csea urchin\u201d shape, the fiber couldn\u2019t be used in a functional battery.<\/p>\n\n\n

\u201cWhen the graphene and manganese dioxide were well-mixed, you can use the fiber to create a functional battery,\u201d said the study\u2019s first author, Nakarin Subjalearndee, a former graduate student at NC State. \u201cIf the manganese dioxide was shaped like a sea urchin, it meant the cathode thread had a rough surface, and could not be used.\u201d<\/p>\n\n\n

\u201cThe rod-shaped manganese dioxide gave us the best performance,\u201d Gao added. \u201cThese particles mimicked the configuration or geometry of the fiber, as compared to the sea urchin-shaped particles, which were round with all kinds of edges pointing out. They disturbed the stacking of the graphene oxide nanosheets within the fiber.\u201d<\/p>\n\n\n

Though the battery\u2019s performance was low, the researchers were able to use it to power a wrist watch. The team wants to continue their work to improve the design\u2019s performance.<\/p>\n\n\n

\u201cThis study shows that the shape and size of the additives in the fiber affected the fiber formation process of graphene oxide,\u201d Gao said. \u201cWe hope to keep developing this system; we want our design to be comparable to a commercial battery.\u201d<\/p>\n\n\n

Abstract:<\/strong> We present the fabrication of graphene oxide (GO) and manganese dioxide (MnO2) composite fibers via wet spinning processes, which entails the effects of MnO2 micromorphology and mass loading on the extrudability of GO\/MnO2 spinning dope and on the properties of resulted composite fibers. Various sizes of rod and sea-urchin shaped MnO2 microparticles have been synthesized via hydrothermal reactions with different oxidants and hydrothermal conditions. Both the microparticle morphology and mass loading significantly affect the extrudability of the GO\/MnO2 mixture. In addition, the orientation of MnO2microparticles within the fibers is largely affected by their microscopic surface areas. The composite fibers have been made electrically conductive via chemical or thermal treatments and then applied as fiber cathodes in Zn-ion battery prototypes. Thermal annealing under an argon atmosphere turns out to be an appropriate method to avoid MnO2 dissolution and leaching, which have been observed in the chemical treatments. These rGO\/MnO2 fiber cathodes have been assembled into prototype Zn-ion batteries with Zn wire as the anode and xanthan-gum gel containing ZnSO4 and MnSO4 salts as the electrolyte. The resulted electrochemical output depends on the annealing temperature and MnO2 distribution within the fiber cathodes, while the best performer shows stable cycling stability at a maximum capacity of ca. 80 mA h\/g.<\/p>\n
