Abstract
Provided is an electrode for a secondary battery, a method of manufacturing the same, and a secondary battery including the electrode.
Claims17
An electrode for a secondary battery comprising:
- a current collector;
- and
- an electrode active material layer disposed on at least one surface of the current collector,
- wherein the electrode satisfies the following Relation 1:
- t2≤t1≤8×t2 [Relation 1]
- wherein t1 is a thickness of the electrode active material layer excluding the current collector on the side close to the current collector based on a separated position within the electrode active material layer when a 90° bending adhesive strength of the electrode is measured, and t2 is a particle size (D50) of an electrode active material included in the electrode active material layer.
