Abstract
An electrolyte injection hole is formed in a current collector extension part between negative and positive active material layers of a quasi-bipolar electrode, and another electrolyte injection hole corresponding to the electrolyte injection hole of the quasi-bipolar electrode is formed in a sidewall of a hollow core around which the electrode is wound, so as to easily inject a predetermined amount of electrolyte into each unit cell of an electrode assembly through an electrolyte injection port and the core. Therefore, simple, reliable, and easy-to-manufacture electrochemical cell can be provided.
