▎ 摘 要
NOVELTY - Current collector, comprises a high molecular polymer, a conductive polymer, a dopant for the conductive polymer, and carbon tube. The mass ratio of the high molecular polymer, the conductive polymer, and the carbon tube is (20-25): (65-75): (5-10). The dopant is 5-50%, preferably 10-30% of the molar mass fraction of the conductive polymer. USE - The current collector is useful in battery anode and/or cathode (claimed). ADVANTAGE - The current collector not only has the characteristics current collector, but also can realize light weight of the current collector and also can improve the liquid retention coefficient of the electrolyte. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of current collector.
