Electrode assembly

摘要

Disclosed is an electrode assembly (10) including a positive electrode (11) including a positive active material (11b) coated on a positive current collector (11a), a negative electrode (12) including a negative active material (12b) coated on a negative current collector (12a), and a separator (13) interposed between the positive (11) and negative (12) electrodes, wherein the outermost electrode (14) disposed on the outermost side among the positive electrodes (11) and the negative electrodes (12) includes a mesh outer current collector (14a) and an active material layer (14b) that is thinner than the active material layers (11b,12b) of positive or negative electrodes disposed inside the electrode assembly (10).
