Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A BATTERY OF AT LEAST TWO FLAT GALVANIC CELLS OF THE TYPE HAVING A CATHODE AND AN ANODE OF THIN, FLAT CONFIGURATION,A POROUS NONCONDUCTIVE SEPARATOR BETWEEN THE CATHODE AND THE ANODE,AND A CONDUCTIVE ELECTROLYTE CONTACTING THE ANODE, THE CATHODE AND THE SEPARATOR, THE CELL BEING DISPOSED IN THE SAME PLANE AND SPACER APART FROM ONE ANOTHER, WHEREIN THE IMPROVEMENT COMPRISES AT LEAST ONE FIRST PLATE CURRENT COLLECTOR CONTACTING AN ANODE AND CATHODE OF TWO ADJACENT CELLS ANS PROVIDING AT LEAST PART OF A SIDEWALL OF THE BATTERY, AND TWO SECONDPLATE CURRENT COLLECTORS, EACH CONTACTING RHE OPPOSITE ELECTRODE OF ONE CELL WITH WHICH A FIRST PLATE CURRENT COLLECTOR IS IN CONTACT, THE SECOND PLATE CURRENT COLLECTOR PROVIDING AT LEAST PART OF A SIDEWALL OF THE BATTERY.
