▎ 摘  要

NOVELTY - Flexible electrode comprises a flexible conductive base film with pores and electrode components dispersed in the flexible conductive base film. The electrode component includes an active material and a conductive agent, and the material of the flexible conductive base film includes conductive plastic. USE - Flexible electrode is used for lithium ion battery (Claimed). ADVANTAGE - The electrode component and the conductive plastic base film are tightly combined to form a unified body, which not only makes the electrode have inherent flexibility, but also can inhibit the active material and the conductive agent from dropping; when assembling the lithium ion battery, it is good for improving the stability of the electrode so as to improve the electrochemical performance of the battery; and it is good for promoting the commercial application of the flexible lithium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a flexible electrode, which involves: (A) dry-mixing of electrode components, the electrode components including active materials and conductive agents, to obtain mixed dry materials, where the electrode components include active materials and conductive agents; (B) adding the mixed dry material and the pore former to the molten conductive plastic and dispersing to obtain a mixed slurry; and (C) forming mixed slurry into a film, and removing the pore forming agent to obtain a flexible electrode.
