LIQUID ELECTROLYTE COMPOSITION AND ITS USE IN GAS SENSORS
First Claim
1. A liquid electrolyte obtainable by combining a first component comprising bistrifluoromethanesulphonimide and/or an analogue thereof with a second component comprising at least one of a dialkyl sulfone, diaryl sulfone, alkyl aryl sulfone, alkyl acyl sulfone, boric acid, alkyl boronic acid, aryl boronic acid, dialkyl phosphite, trialkyl phosphite, dialkyl phosphate, trialkyl phosphate, alkylene carbonate, alkanoic lactone, preferably alkanoic γ
- -lactone an analogue of any of these, or mixtures thereof, wherein any of the alkyl, aryl of alkenyl groups may be substituted or unsubstituted.
