PURPOSE: To prevent a battery from deteriorating during its preservation by contacting a positive electrode with a battery case as a positive electrode terminal via a linear current collector to thereby omit the molding and machining works of the collector and to remove machining stress strain at the respective steps.
CONSTITUTION: There are disposed cathode active substance 6 of lithium sheet or the like and anode active substance 8 containing mainly graphite fluoride or the like via a separator 7 within a ferrite stainless steel case 2 of 30 chromium-2 molybdenum or the like. A current collector 9 between the anode active substance 8 and the case 2 uses, for example, a wire of ferite stainless steel such as 26 chromium-1 molybdenum stainless steel, 30 chromium-2 molybdenum stainless steel, or 18 chromium stainless steel, etc., austenite stainless steel such as 18 chromium-8 nickel stainless steel, etc., or bulk metal such as titanium, etc.
