▎ 摘　　要

NOVELTY - The electrode has a polyimide substrate and an active material film layer connected together. The polyimide substrate is provided with a polyimide film. A surface of the polyimide film is printed with an etched pattern and connected with first conductive film layer. The first conductive film layer is connected with the active material film layer. Another surface of the polyimide film is formed with second conductive film layer. USE - Polyimide-based flexible electrode for a flexible lithium secondary battery (claimed). ADVANTAGE - The electrode is light in weight and thinner in thickness, has better flame retarding effect, and can be repeatedly bent. The active material film layer is tightly combined with a current collector so as to control appearance and thickness of the electrode, thus improving electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a polyimide-based flexible electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a polyimide-based flexible electrode for a flexible lithium secondary battery.
