MECHANICALLY RECHARGED OXYGEN (AIR)-METAL CHEMICAL CURRENT SOURCE Russian patent published in 1998 - IPC

FIELD: chemical current sources. SUBSTANCE: chemical current source has case accommodating two parallel cathode with expendable anode in the form of flat plate placed inbetween as well as anode current collector with one or more contact peds. Anode current collector is arranged in internal space of current source in parallel with cathode surface so that contact pads are directed towards anode and rigidly fixed in case; anode is pressed on one side to current collector contact pads and spring-loaded member rigidly coupled with case is pressed to other anode surface opposing contact pads. Spring-loaded member may be made of conducting material or may have conducting layer at part pressed to anode and electrically connected to anode current collector. It may be placed in cathode-to-cathode gap. Current collector contact pads may be made in the form of stampings on current collector surface. Anode current collector may be placed in current source electrolyte. EFFECT: improved reliability of electric contact, facilitated change of spent anodes, provision for using anode plates of different thickness, improved utilization material. 5 cl, 1 dwg
