Title:
SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/211941
Kind Code:
A1
Abstract:
The present invention provides a method which is for manufacturing a secondary battery, and which is capable of more sufficiently preventing uneven charging caused by bubbles in the secondary battery as a whole even when the secondary battery has a notched part. This method for manufacturing a secondary battery includes a step for performing initial charging of a secondary battery precursor 50 obtained by sealing, in an exterior body, an electrolyte and an electrode assembly 1 that has a notched part in a plan view and that includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. In the secondary battery precursor 50, the initial charging is carried out while a gas generated in the electrode assembly 1 is removed at least to a notched part 10 of the electrode assembly 1.
