▎ 摘　　要

NOVELTY - Lithium/sodium ion battery cathode material comprises cell counting kit-8 (CMK-8), nickel diselenide (NiSe2) octahedral microcrystalline, graphene-type molybdenum disulfide, carbon nano tube and cysteine. USE - Used as lithium/sodium ion battery cathode material. ADVANTAGE - The material greatly improves the charging and discharging specific capacity of the lithium/sodium ion, effectively avoids the volume expansion of the cathode material, and prolongs the service life of the cathode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the material, comprising (i) ultrasonically dispersing the weighed CMK-8 in water to form a CMK-8 suspension; and (ii) adding graphene-type molybdenum disulfide to the CMK-8 suspension while stirring, adsorbing, adding NiSe2 octahedral microcrystals and cysteine, adding carbon nanotubes, ultrasonically processing under power of 60-100 W for 2-5 hours, drying, calcining in a nitrogen atmosphere at 800-900 degrees C for 3-4 hours, grinding and drying.
