Abstract
A problem of the present invention is to provide a liquid electrolyte for a fluoride ion battery, in which fluoride anion conductivity is imparted to an ionic liquid containing fluoride complex anions. The present invention solves the problem by providing a liquid electrolyte for a fluoride ion battery, which comprises an ionic liquid containing specific fluoride complex anions and an anion acceptor having a specific acceptor number.
Claims4
A liquid electrolyte for a fluoride ion battery, comprising:
- an ionic liquid containing a fluoride complex anion represented by the following general formula (1), and
- an anion acceptor with an acceptor number of 75 or more;
- or
- an ionic liquid containing a fluoride complex anion represented by the following general formula (2), and
- an anion acceptor with an acceptor number of 70 or more,
- in which, A1 to A8 are each independently fluorine, an alkyl group with a carbon number of 5 or less, a fluoroalkyl group with a carbon number of 5 or less, or an ether group such that part of carbon of the alkyl group or the fluoroalkyl group is substituted with oxygen.
