Lithium-ion secondary battery |
| abstract |
An object of the present invention is to provide a lithium ion secondary battery in which an increase in internal resistance is suppressed and a halogenated cyclic acid anhydride is used as an electrolyte additive. The lithium ion secondary battery according to the present invention is characterized by comprising a positive electrode formed with a porous layer containing an insulating filler and an electrolyte containing the halogenated cyclic acid anhydride in an amount of 0.005 to 10% by weight. |
