Abstract
A battery includes an anode having a lithium alloy as the active material, a cathode having, for example, iron disulfide as the active material, and an electrolyte containing a sulfolane and 1,2-dimethoxyethane.
Claims24
A battery, comprising a housing, and within the housing:
- (a) an anode comprising a lithium alloy;
- (b) a cathode comprising a cathode active material selected from the group consisting of transition metal polysulfides having the formula M1aM2bSn, wherein M1 and M2 are transition metals, a+b is at least 1, and n is at least 2×(a+b);
- and
- (c) an electrolyte comprising from 1% to 30% by volume of a sulfolane and from 35% to 99% of 1,2-dimethoxyethane.
