Abstract
The present invention provides for a battery having an anode, a cathode, and a flame-retarding electrolyte with a conductivity greater than about 10−3 S/cm at ambient temperature and which includes a compound that chemically interferes with flame propagation.
Claims2
A battery comprising:
- an anode;
- a cathode;
- and
- an electrolyte having conductivity greater than about 10−3 S/cm at ambient temperature and which includes a compound that chemically interferes with flame propagation;
- wherein the compound that chemically interferes with flame propagation comprises a compound having the general structure:
- wherein X is oxygen;
- wherein R1 is a C1 to C12 alkyl moiety that is terminally substituted with zero to three halogen atoms;
- wherein R2 is a C1 to C12 alkyl moiety that is terminally substituted with zero to three halogen atoms;
- wherein Z is an oxy derivative of an aryl moiety;
- wherein m is an integer from 1 to 4;
- and
- wherein the compound that chemically interferes with flame propagation is selected from the group consisting of:
- diethyl(2,6-di-tert-butyl-4-methylphenyl)phosphate and benzene-1,4-bis-diethylphosphate.
