NOVELTY - The cell has a spacer e.g. ring spacer, arranged between a battery cell terminal and a bursting disc and ensuring venting of the cell responsive to disruption internal and external to the cell. A top piercing element placed on the bursting disc pierces the terminal. A bottom spacer is placed opposite of the top piercing element relative to the bursting disc. The spacer prevents clogging of vents of the terminal via deformation of the terminal in response to external force i.e. crushing force, and internal force that includes force from a buildup of gas within the cell.    USE - Battery cell i.e. rechargeable lithium-ion battery cell, for powering an electric motor of an automobile e.g. electric powered automobile such as car, and a main memory of a computer system (all claimed) e.g. laptop personal computer system such as ThinkPad (RTM: series of personal computers). Can also be used for an electronic device e.g. notebook computer, cell phone and mobile computing device such as personal digital assistant (PDA), smart phone and mobile phone, and a mobile device such as battery-operated power drill, saw, mower and weed cutter.    ADVANTAGE - The cell includes a double acting venting mechanism providing reliable venting even in response to different undesirable events so as to provide safe venting when the cell encounters internal/external pressure and deformation. The cell facilitates gas escape without clogging the vent and avoids gas buildup with a room for a venting valve to operate in a consistently smooth manner. The double acting venting mechanism is applicable to all cell manufacturers regardless of venting design differences. The cell eliminates potential explosion risk. The double acting venting mechanism can be implemented in a quick manner and at low cost by the cell manufacturers.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an apparatus comprising battery powered elements.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of battery cell terminals in normal, current interrupt device disconnecting and venting conditions.    Washer (105)
