<p>A reserve battery cell which includes a battery cell housing (l4), an anode and cathode collector, and a reservoir housing (l6) which includes a quantity of electrolyte (l2) which, when applied to the anode and cathode collector, cause the battery to generate an electric current through an external load. Burst discs (9,ll) are located proximate the extremities of the reservoir housing (l6). The upstream burst disc (9) is capable of rupturing upon the application of sufficient externally applied pressure while the downstream burst disc (ll) is capable of rupturing upon the application of sufficient hydraulic pressure exerted thereon by the electrolyte. The piston (l0) is located within the reservoir housing (l6) which establishes the upstream boundary of the electrolyte (l2) and which is capable of travelling down the reservoir housing (l6) upon the application of an externally applied pressure and which is characterised as preventing electrolyte (l2) from leaking around the piston (l0) and any substantial amount of gas from entering the electrolyte (l2) through the piston body. </p> |
