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

FIELD: chemical current sources. SUBSTANCE: chemical current source has case, case cover, two case-mounted parallel cathodes with expandable anode placed inbetween, and current anode collector. The latter is arranged in inner cavity of source on case cover side, along one of cathode ribs, and rigidly fixed within case. Anode is made in the form of plate bent out in parallel to one of ribs and is pressed with its bent-out part to current collector; spring-loaded member is pressed to bent-out part of anode on side opposite current collector and its opposite part rests on case cover. Anode bent is made at angle of 15 to 90 deg. to its working surface. Current source may be provided, in addition, with anode current collector placed in parallel to main one and anode bend may be made in either side of its working surface. Spring-loaded member may be of conducting material or may have conducting layer at point contacting anode. Anode current collector may be arranged either in source electrolyte or beyond it. EFFECT: improved electric contact, facilitated change of spent anode, provision for using anode plates of different thickness, improved utilization of anode material. 5 cl, 1 dwg
