Abstract
Official abstract text for this publication.
A secondary battery having good performance especially in a high-temperature environment can be obtained by using an electrolyte solution for secondary batteries, which is characterized by containing an ionic liquid represented by formula (1) and a lithium salt. (In the formula, each of R 1 and R 2 independently represents an alkyl group having 1-5 carbon atoms; and n represents 1 or 2.)
First claim
Opening claim text (preview).
The invention claimed is: 1. A secondary battery, which is an air battery, comprising: an air positive electrode layer being supplied with oxygen, a negative electrode layer, and a separator between the air positive electrode layer and the negative electrode layer, the separator being impregnated with a liquid electrolyte comprising an ionic liquid of formula (1) and an ion-conductive salt and wherein R 1 and R 2 are each independently an alkyl group of 1 to 5 carbon atoms, and n is 2, wherein the liquid electrolyte is free of organic solvent, and wherein a concentration of the ion-conductive salt in the liquid electrolyte is from about 0.8 to about 2 mol/L. 2. The secondary battery according to claim 1 , wherein R 1 and R 2 are each independently a methyl group or an ethyl group. 3. The secondary battery according to claim 1 , wherein R 1 and R 2 are both methyl groups. 4. The secondary battery according to claim 1 , wherein the liquid electrolyte consists solely of the ionic liquid of formula (1) and the ion-conductive salt. 5. The secondary battery according to claim 1 , wherein the ion-conductive salt is a lithium salt. 6. The secondary battery according to claim 4 , wherein the ion-conductive salt is a lithium salt. 7. The secondary battery according to claim 5 , wherein the lithium salt is one or more selected from the group consisting of lithium tetrafluoroborate, lithium hexafluorophosphate, lithium bis(trifluoromethanesulfonyl)amide and lithium bis(fluorosulfonyl)amide.
