▎ 摘　　要

NOVELTY - Preparing molybdenum trioxide/reduced graphene oxide composite fiber, comprises (i) performing hydrothermal reaction to ammonium molybdate and nitric acid aqueous solution to obtain molybdenum trioxide nanobelt, (ii) adding graphene oxide dispersion liquid into aqueous solution of molybdenum trioxide nanobelt and stirring to obtain composite spinning solution, (iii) spinning composite spinning solution to prepare molybdenum trioxide/graphene oxide composite fiber, and (iv) reducing the molybdenum trioxide/graphene oxide composite fiber. USE - The composite fiber is useful in cathode material (claimed). ADVANTAGE - The method has mild condition and simple operation, and is suitable for mass production. The composite fiber has stronger multiplying power and circulating electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for molybdenum trioxide/reduced graphene oxide composite fiber, prepared by the above method and the length of the composite fiber is more than 20 cm. DESCRIPTION OF DRAWING(S) - The drawing shows flow chart illustrating preparation of the molybdenum trioxide/reduced graphene oxide composite fiber (Drawing includes non-English language text).
