▎ 摘　　要

NOVELTY - The method involves supporting a stacked conductive two-dimensional sheet material by a conductive three-dimensional spherical structure material as a core electrode structure. The conductive flexible woven material is used as a shell electrode. The flexible woven material is twisted in the same direction by different spinning methods to cover the core electrode to obtain a core-shell coaxial fiber electrode. The conductive flexible woven material has carbon nanomaterials i.e. carbon nanotubes, graphene, carbon nanofibers, metal oxide nanowires, and metal nanowires. USE - Method for preparing low-temperature core-shell coaxial fiber electrode in room temperature and low temperature resistant environment electrode materials. ADVANTAGE - The method enables to prepare low-temperature core-shell coaxial fiber electrode that has high specific capacity or high mechanical strength, and realizes the common lifting of energy storage performance and mechanical property of the composite fiber electrode at low temperature. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the preparation of carbon nanotube/Mxene core-shell coaxial structure fibers (Drawing includes non-English language text).
