摘要： An electrode assembly and a secondary battery having the same improve efficiency and stability of the secondary battery. The electrode assembly includes: a positive electrode plate having a positive electrode collector on which a positive electrode coating portion and a positive electrode non-coating portion are formed; a negative electrode plate having a negative electrode collector on which a negative electrode coating portion and a negative electrode non-coating portion are formed; a separator disposed between the positive electrode plate and the negative electrode plate; and an insulating member disposed on one side of the positive or negative electrode non-coating portion, and formed adjacent to at least one of the ends of the positive electrode coating portion and/or at least one of the end of the negative electrode coating portion. The electrode assembly at least prevents damage to a separator generated due to non-uniformity of the ends of the electrode coating portion.
