ABSTRACT:
The nonaqueous electrolyte battery of this invention is provided with a spiral electrode unit comprising a separator laminated between a cathode and an anode rolled into a spiral shape having anode around the outer perimeter. An anode terminal tab disconnects from the outermost one circumference of anode residue after discharge to prevent residual anode deposition on the cathode when power is overdrawn.
