Abstract
A current producing Li/TiS.sub.2 electrochemical cell is featured which has a cyclic ether-containing electrolyte, and an inhibitor against the polymerization of the cyclic ether by TiS.sub.2, which cyclic ether otherwise polymerizes in the presence of TiS.sub.2.
Claims12
In a current producing Li/TiS.sub.2 electrochemical cell having an electrolyte containing at least one lithium salt solute in a solvent comprising a cyclic ether, at least one composition for inhibiting polymerization of said cyclic ether by TiS.sub.2, said composition being selected from a group consisting essentially of at least one of the following:
- (a) Li.sub.x TiS.sub.2
- where:
- x is less than approximately 0.1 and greater than approximately 0.025;
- and
- (b) at least one sterically hindered amine which does not intercalate with TiS.sub.2.
