▎ 摘　　要

NOVELTY - A nickel-reduced graphene oxide composite structured nanowire comprises mixture of nickel-reduced graphene oxide, where the nanowire has diameter of 5-200 nm and length of 1 um-3 mm. USE - Nickel-reduced graphene oxide composite structured nanowire for use as coating material on copper negative electrode tab of lithium-ion battery (claimed). ADVANTAGE - The nickel-reduced graphene oxide composite structured nanowire improves stability of electrode tab and battery safety and stability and reduces Ohmic resistance of battery to 10-24% and polarized heat generated during long battery cycling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing the nickel-reduced graphene oxide composite structured nanowire.
