Abstract
Provided is an electrolyte for a non-aqueous electrolyte battery, which can provide, when used in a non-aqueous electrolyte battery, in a good balance, an effect to suppress an increase in an internal resistance at a low temperature and an effect to suppress an increase in an amount of gas generated at a high temperature, as well as a non-aqueous electrolyte battery containing such an % electrolyte. The non-aqueous electrolyte comprises a non-aqueous solvent and at least a hexafluorophosphate and/or tetrafluoroborate as a solute, and further comprises at least one imide anion-containing salt represented by the following general formula [1] but does not contain a silane compound represented by the following general formula [2] or an ionic complex represented by, for example, the following general formula [3].
