Abstract
Official abstract text for this publication.
A method for manufacturing a battery, including: a first injection step of injecting a first electrolytic solution that contains lithium bis(fluorosulfonyl)imide into an electrode body having a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; a first charging step of performing first charging after the first injection step; a first aging step of performing aging treatment after the first charging step; a second injection step of injecting a second electrolytic solution that does not contain lithium bis(fluorosulfonyl)imide into the electrode body after the first aging step; a second charging step of performing second charging after the second injection step; and a second aging step of performing aging treatment after the second charging step.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing a battery, comprising: a first injection step of injecting a first electrolytic solution that contains lithium bis(fluorosulfonyl)imide into an electrode body having a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; a first charging step of performing first charging after the first injection step; a first aging step of performing aging treatment after the first charging step; a second injection step of injecting a second electrolytic solution that does not contain lithium bis(fluorosulfonyl)imide into the electrode body after the first aging step; a second charging step of performing second charging after the second injection step; and a second aging step of performing aging treatment after the second charging step. 2 . The method for manufacturing a battery according to claim 1 , wherein the second electrolytic solution contains lithium hexafluorophosphate. 3 . The method for manufacturing a battery according to claim 1 , wherein a working potential of a positive-electrode active material included in the positive electrode is 4 V (vs. Li/Li + ) or less.
