ELECTROCHEMICAL CELL HAVING A FOLDED ELECTRODE AND SEPARATOR, BATTERY INCLUDING THE SAME, AND METHOD OF FORMING SAME

摘要

An electrochemical cell including a folded electrode layer and a folded separator, a battery including the electrochemical cell, and methods of forming the electrochemical cell and battery are disclosed. The electrode layer is folded in a first direction and the separator is folded in a second direction, such that the first direction and second direction are orthogonal each other.
