Claims
- 1. An electrochemical cell employing an anode of alkali or alkaline earth metals, a cathode material capable of forming a cell with said anode material, and a non-aqueous electrolyte solution, said non-aqueous electrolyte solution comprising an electrolyte solvent of the following general formula: ##STR9## wherein R is a C.sub.1 -C.sub.10 alkyl group;
- X is a C.sub.1 -C.sub.8 acyclic group which can be linear, branched, saturated or unsaturated; and
- Y is a C.sub.1 -C.sub.10 alkyl group or a carbonyl group ##STR10## in which R' is a C.sub.1 -C.sub.10 alkyl group; and and electrolyte material soluble in said electrolyte solvent.
- 2. The electrochemical cell of claim 1, wherein in the non-aqueous electrolyte solution:
- R is a C.sub.1 -C.sub.4 alkyl group;
- X is a C.sub.1 -C.sub.3 acyclic group; and
- Y is a C.sub.1 -C.sub.4 alkyl group or a carbonyl group ##STR11## in which R' is a C.sub.1 -C.sub.4 alkyl group.
- 3. The electrochemical cell of claim 1, wherein in the non-aqueous electrolyte solution;
- R is a methyl or ethyl alkyl group;
- X is an alkylene group selected from methylene or ethylene; and
- Y is a methyl or ethyl alkyl group or a methyl carbonyl or ethyl carbonyl group.
