Abstract
Official abstract text for this publication.
An incombustible lithium secondary battery, which has excellent battery capacity and high safety, contains a separator provided between a positive electrode and a negative electrode, and a nonaqueous electrolytic solution containing a lithium salt, in which the nonaqueous electrolytic solution employs an ionic liquid as a solvent, and the separator contains an electrically insulating porous inorganic membrane and a substrate. The ionic liquid may contain a bis(fluorosulfonyl)imide anion as an anionic component, and may contain a cation containing a nitrogen atom as a cationic component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithium secondary battery comprising a separator provided between a positive electrode and a negative electrode; a nonaqueous electrolytic solution containing a lithium salt, the nonaqueous electrolytic solution comprising a solvent including an ionic liquid that has a bis(fluorosulfonyl)imide anion as an anionic component and a cationic component selected from a methylpropylpiperidinium cation and a methylpropylpyrrolidinium cation; the separator com…
