ELECTRODE ASSEMBLY AND ELECTROCHEMICAL ELEMENT COMPRISING SAME

Original (Chinese)

An electrode assembly including a negative electrode structure and a plurality of positive electrodes is provided. The negative electrode structure includes first and second separating films, and a negative electrode including a lithium metal layer interposed between the first and second separating films. The negative electrode structure includes a plurality of stack portions and a plurality of folding portions. The electrode assembly has a configuration in which the stack portion of the negative electrode structure and the positive electrode are stacked alternately and sequentially. the negative electrode structure includes a plurality of negative electrode tabs that protrude from the negative electrode structure and past the first and second separating films in a width direction. The number of the negative electrode tabs is one less or fewer than a number of stack portions of the negative electrode structure.
