A lithium primary cell battery, comprising:
- a lithium metal as an active anode material, and
- a carbon monofluoride as an active cathode material,
- an electrolyte comprising a boron compound,
- wherein the primary cell is a non-rechargeable cell and configured to operate at open circuit voltages no greater than 3.4 volts;
- wherein the boron compound is a compound according to formula (1), (2), (3), (4), (7) or (8):
- wherein
- each of R1, R2, R3, R4 and R5 independent from one another is selected from the group consisting of hydrogen, alkyl, alkenyl, cycloalkyl, thioether, heterocyclic compounds, aryl and heteroaryl, wherein R1, R2, R3, R4 or R5 is not thiophene.
Use of a boron compound as the electrolyte additive of a lithium primary cell battery comprising lithium metal as an active anode material, a carbon monofluoride as an active cathode material, and an electrolyte comprising the boron compound, wherein the lithium primary cell battery is a non-rechargeable cell and is configured to operate at open circuit voltages no greater than 3.4 volts, wherein the boron compound is a compound according to formula (1), (2), (3), (4), (7) or (8):
- wherein
- each of R1, R2, R3, R4 and R5 independent from one another is selected from the group consisting of hydrogen, alkyl, alkene, cycloalkyl, thioether, heterocyclic compounds, aryl and heteroaryl, wherein R1, R2, R3, R4 or R5 is not thiophene.
