<p>The present invention relates to a manufacturing method of secondary batteries and, more specifically, a manufacturing method of secondary batteries, which is allowed to resolve the problem of generating wrinkles in a separator in a process of injecting an electrolyte when secondary batteries are manufactured. For this, in the present invention, provided is a manufacturing method of secondary batteries, comprising a step of sealing an electrode assembly having stacked positive electrode plates, negative electrode plates and separators except for an inlet hole for the electrolyte after the electrode assembly is stored in a packaging material.</p> |
