METHOD OF MANUFACTURING FLAT BATTERY AND ITS MANUFACTURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high-accuracy and high-efficiency manufacturing method for rapidly injecting a minute quantity of electrolyte even for an ultraminiature battery small in electric capacity of a flat battery; and to provide a manufacturing device.

SOLUTION: An electrolyte pressure-fed from an electrolyte tank 20 is injected into an upper case 1 having an injection valve 8 in a boundary between an electrolyte syringe 7 and an injection nozzle 16 and composed by stacking and housing a negative electrode body 4 and a separator 5 of an electrode body housed in a decompression chamber 9 reduced in pressure from the injection nozzle 16 by opening/closing the valve, and thus the electrolyte without being exposed to the atmosphere and decompressed air for a long time is accurately and efficiently injected.
