▎ 摘　　要

NOVELTY - Use of graphene film for negative electrode of a lithium metal battery, is claimed, the graphene film is introduced as an interlayer between a lithium negative electrode and a separator. USE - Graphene film for negative electrode of a lithium metal battery, symmetric battery and a full battery (all claimed). ADVANTAGE - The negative electrode can be stably cycled at 1 mA/cm2 and 1 mAh/cm2 for more than 500 hours, and has long service life and a long life cycle under a large current (10 mA/cm2), smaller interface impedance, better interface stability and faster charge transfer rate, and ensures good performance in full battery with positive electrode of lithium iron phosphate, lithium cobalt oxide and air electrode. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a symmetric battery (2) a full battery.
