An electrode assembly includes first and second electrodes stacked in a stacking direction with a separator therebetween. The first electrode includes a first coating portion coated with a first electrode active material and a first non-coating portion at a side of the first coating portion without being coated with the first electrode active material, and the second electrode includes a second coating portion coated with a second electrode active material and a second non-coating portion at a side of the second coating portion without being coated with the second electrode active material. The first non-coating portion and the second non-coating portion are not overlapped in the stacking direction.

Electrode, electrode assembly and secondary battery containing the same

A charge/discharge pressurizing device includes a first pressurizing jig configured to pressurize one surface of an electrode lead of a battery cell, a second pressurizing jig configured to pressurize an other surface of the electrode lead facing the one surface of the electrode lead, a guide configured to be disposed to be spaced apart from the one surface of the first pressurizing jig by a predetermined distance, and a first pressurizing jig controller configured to be connected to the first pressurizing jig and to move the first pressurizing jig toward the one surface of the electrode lead.
