▎ 摘　　要

NOVELTY - Nickel-based alloy-graphene current collector comprises composite coating coated or deposited on both sides of the current collector, and the composite coating is an amorphous nanocrystalline composite coating that uses graphene as a core to induce the growth of a nickel-boron alloy. USE - The collector is useful in lithium ion battery (claimed). ADVANTAGE - The Ni-based alloy graphene layer has excellent corrosion resistance and can adapt to various electrolyte systems e.g. LITFSI; graphene has excellent electrical conductivity, which can reduce the direct contact resistance between the active material and the current collector and improves the electrochemical performance of the cell. The prepared composite coating has a strong binding force with the current collector and the active material, which can avoid the performance failure caused by the active material falling off and excellent thermal conductivity, which can reduce the thermal runaway of battery cells and improve safety performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the Ni-based alloy-graphene current collector, comprising (a) dispersing nickel salt, boron salt, graphene and additive uniformly in solvent to obtain composite plating solution, and (b) coating or depositing composite plating solution and current collector with a composite plating layer at two sides of the current collector by means of chemical plating or electro-deposition.
