Title:
METHOD FOR PRODUCING LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/077293
Kind Code:
A1
Abstract:
In this method for producing a lithium-ion battery: a positive electrode plate (5), a separator (7) and a negative electrode plate (6) are prepared; the positive electrode plate (5), the separator (7) and the negative electrode plate (6) are combined so as to form an electrode plate group that is wound in a spiral shape; a heat-sensitive adhesive (preferably a heat-sensitive adhesive tape (10)) having a property in which the adhesive strength is reduced by heating or cooling is used to secure a winding end portion (9) of the electrode plate group (4); after the electrode plate group (4) has been inserted in an outer case (1), the ambient temperature of the electrode plate group (4) is adjusted in such a manner that the electrode plate group (4) is loosened by a reduction in the adhesive strength of the heat-sensitive adhesive; and an electrolyte is injected in the outer case (1).
