An electrode assembly having an outermost anode and a lithium ion battery with the electrode assembly

摘要

An electrode assembly according to the present invention comprises: at least one unit cell including a pair of electrode plates having different polarities with a separation membrane interposed therebetween; an electrode mixture applied on one or both surfaces of the pair of electrode plates; and electrode tabs positioned at edges of the electrode plates and not yet coated with the electrode mixture. The electrode tab comprises an electrode parallel connection tab and an electrode lead connection tab. The electrode plates are formed with at least one electrode tab from the electrode parallel connection tab and the electrode lead connection tab, and the outermost electrode plate is in a negative electrode state. According to the present invention, energy density loss is minimized.
