摘要： A pressure tolerant high energy density battery (10) is described. The battery has a metal casing (12) having a pressure compensating means in the form of bellows (30) comprising a plurality of successive convolutions individually welded to one end of the battery opposite a terminal conductor (20). The conductor is mounted on the header (18) by a glass seal (22) and the active components for the battery comprise a cathode means (34) preferably made of either carbon or fluorinated carbon (CFx) and a binder sheeted on a metal foil and an anode means (36) preferably made by laminating battery grade lithium onto metal grids. A separator (38) is provided between the active battery components and the electrodes and separator are rolled into a spirally wound type formation and housed inside the battery, supported above the bellows. The casing is then preferably filled with a suitable liquid electrolyte comprising gamma butyrolactone having an electrolyte salt in a Li/CFx battery and chlorinated sulfuryl chloride in a Li/CSC battery, and hermetically sealed. A vent (32) is preferably provided to relieve pressure inside the battery.
