Electrode assembly and secondary battery having the same

Abstract

A secondary battery, which may include an electrode assembly, a can having an upper opening to receive the electrode assembly and a cap assembly finishing the opening of the can is disclosed. The electrode assembly may include a positive electrode plate provided with a positive electrode active material layer, a negative electrode plate provided with a negative electrode active material layer, a separator interposed between the positive electrode plate and the negative electrode plate and an insulation coating layer coated on the positive electrode plate. The insulation coating layer may includes a first coating layer coated on the positive electrode coating portion. The insulation coating layer may contain olivine type lithium phosphate compound. A second coating layer coated on the first coating layer may contain ceramic powder and a binder.
