Lithium-ion secondary battery |
| abstract |
The technical problem of the present invention is to solve the problem of decomposition products of cyclic esters that cause cycle deterioration and storage deterioration of lithium ion secondary batteries. As a means of solving the problem, lithium ion secondary batteries include: a positive electrode; a graphite-based carbon material as a A negative electrode of a negative electrode active material; an electrolyte solution obtained by dissolving a lithium salt in a non-aqueous solvent containing a cyclic ester; and a shielding layer (15) or a catcher, the shielding layer (15) preventing the cyclic ester from interacting with the In contact with the negative electrode, the capture material captures the decomposition product of the cyclic ester generated at the negative electrode. |
