Abstract
The present invention relates to electrolyte solvents for use in liquid or rubbery electrolyte solutions. Specifically, this invention is directed to boron-containing electrolyte solvents and boron-containing electrolyte solutions.
Claims44
A boron-containing electrolyte solution, said electrolyte solution comprising:
- (i) an electrolyte solute;
- and,
- (ii) a boron electrolyte solvent of the formula:
- ##STR19## wherein X is a halogen atom;
- R.sub.1 and R.sub.2 may be the same or different and are independently selected from the group consisting of:
- linear aliphatic alkyl groups;
- branched aliphatic alkyl groups;
- and,
- aromatic alkyl groups;
- which alkyl groups may be substituted with substitutents of varying electronegativity.
