NOVELTY - Nickel disulfide cross nano-flower material comprises material form is nickel disulfide cross nano-flower structure anchored on the graphene. USE - Nickel disulfide cross nano-flower material. ADVANTAGE - The nickel disulfide cross nano-flower material improves the mobility of electrons and ions in the charging and discharging process after the graphene is wrapped further improving the ion and electronic conductivity of the material so as to improve the cycle performance and multiplying power performance of the battery, the material can prevent the occurrence of polysulfide in the charging and discharging process, and the flower-shaped structure can also improve the mechanical property of the battery by adapting the volume shrinkage and expansion in the circulation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nickel disulfide cross nano-flower material, which involves: 1. weighing nickel chloride hexahydrate urea L-cysteine powder are respectively added to the deionized water magnetic stirring uniformly, then adding graphene solution performing ultrasonic cleaning treatment to obtain solution A; 2. adding the solution A obtained into the high temperature and high pressure reaction kettle of the polytetrafluoroethylene lining for hydrothermal reaction to obtain the mixed solution A; 3. centrifuging the mixed solution A obtained after processing and then filtering.
