(JP2000123860-A)   NOVELTY - Easy filling of the battery with electrolyte solution and minimization of excessive electrolyte solution in the battery are achieved by providing the solution injection opening, e.g., at one end of the wound electrode body and passing the injection solution needle through the center of the battery core through which the electrolyte solution is injected and extracted by means of a nozzle.    USE - Motor driving power source for an electric vehicle or a hybrid electric vehicle.    ADVANTAGE - The amount of excessive electrolyte solution to be filled into the battery is kept to a minimum level. Filling is simplified. The battery has improved reduction in current collection resistance and improved anti-vibration performance.
