▎ 摘　　要

NOVELTY - Preparing nitrogen-doped molybdenum disulfide/graphene complex material comprises (i) adding graphene oxide in formaldehyde aqueous solution to obtain dispersion A, (ii) adding melamine, molybdenum salt and sulfur powder into deionized water to obtain dispersion B, (iii) mixing dispersion A and dispersion B, heating to 50-80 degrees C, reacting for 10-60 minutes, adjusting the pH of the reaction solution to 7-9, heating to 100-200 degrees C, hydrothermally reacting for 12-24 hours, filtering and drying to obtain black solid powder, (iv) placing black solid powder obtained in step (iii) in microwave reaction chamber, heating with a microwave power of 300-1200W for 1-60min to obtain the nitrogen-doped molybdenum disulfide/graphene complex material. USE - The nitrogen-doped molybdenum disulfide/graphene complex material useful as cathode material for lithium ion batteries (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nitrogen-doped molybdenum disulfide/graphene complex material prepared by the above method.
