▎ 摘 要
NOVELTY - Positive electrode current collector comprises a tab extending from a positive electrode current collector substrate, where an anti-corrosion layer consisting of primer layer, a conductive polymer layer, and a conductive epoxy layer is formed on the entire surface of the tab. USE - Positive electrode current collector for a lithium secondary battery, preferably lithium ion battery, lithium polymer battery, lithium metal battery, or lithium-free battery (all claimed). ADVANTAGE - The positive electrode current collector is capable of preventing corrosion that occurs frequently in a positive electrode current collector tab portion, and improves charge/discharge characteristics and flame retardancy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium secondary battery, which comprises positive electrode, a negative electrode having a negative electrode mixture layer formed on surface of the negative electrode current collector, a separator interposed between the anode and the cathode, and an electrode assembly comprising a lithium non-aqueous electrolyte.
