▎ 摘  要

NOVELTY - Lithium battery cathode electrode comprises a current collector and a cathode electrode slurry layer. The cathode electrode is located on the current collector. A first slurry portion and a second slurry portions are provided on the cathode electrode of the slurry sheet. The slurry layers are alternately provided with multiple slurry parts. The component of the first slurry portion is provided with a graphene, and the content of the graphene in the component is 0. USE - Used as lithium battery cathode electrode. ADVANTAGE - The electrode is capable of reducing the barrier of the diffusion of lithium ion and improving the performance of the lithium battery; has high electron mobility, ultra-high charge carrier mobility, can obviously reduce the battery internal resistance; improves the multiplying power performance and cycle life; and optimizes the fast charging and fast discharging performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of lithium battery cathode electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the lithium battery cathode electrode.
