▎ 摘  要

NOVELTY - Preparing flexible knitted lithium ion battery positive electrode involves uniformly depositing a conductive material layer on a surface of an aluminium wire. The conductive material layer is dried to obtain a finished positive electrode, where the conductive material is formed as a conductive carbon black or conductive graphite material. Surface oil stain of the aluminum wire is removed. The positive electrode is dried. The conductive material, sodium carboxymethyl cellulose and water are mixed to prepare a bottom coating slurry. The prepared bottom coating slurry is uniformly dipped on the prepared aluminum wire. A positive electrode material, a conductive agent and adhesive are mixed to prepare the positive electrode. USE - Method for preparing a positive electrode of a flexible knitted lithium ion battery. ADVANTAGE - The method enables realizing simple and quick operation, and realizing convenient for industrial application, and providing the positive electrode with internal resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a flexible knitted lithium ion battery positive electrode application.
