ELECTRODE ASSEMBLY COMPRISING FIBER-SHAPED STRUCTURES

The present invention relates to an electrode assembly of a battery including fibrous structures. The electrode assembly includes: a first electrode including a plurality of first structures that have fibrous shapes and extend in a first direction; a second electrode including a plurality of second structures that have fibrous shapes and polarities opposite to polarities of the first structures, and extend in a second direction different from the first direction; and a first separator that is disposed between the first structures and the second structures which cross each other, and separates the first structures from the second structures.
