<p>The present invention relates to an energy storage device having a gas release part, which quickly discharges gas generated within a case to the outside regardless of a position at which the device is provided on a substrate. The energy storage device, according to the present invention, comprises a cell, a case body, the gas release part, and a terminal plate. The cell is impregnated with an electrolyte and stores electric energy. The case body has an upper open portion, and an accommodating space in which the cell is accommodated through the open portion. The gas release part comprises: a plurality of through-holes formed on the outer peripheral surface thereof separated at certain intervals from an upper end of the open portion of the case body toward the lower side thereof; and a gas permeable membrane which is formed inside the case body so as to cover the plurality of through-holes, discharges, to the outside, the gas generated when the cell is driven, and blocks the leakage of the electrolyte of the cell. In addition, the terminal plate is electrically connected with the cell and seals the open portion of the case body.</p> |
