Abstract
An electrolytic solution is comprised of a borate, at least one dicarboxylic acid and at least one hydrotropic agent. The hydrotropic agent serves to maintain soluability at low temperatures, for example, in glycol type solvents. The invention also provides use of 1,10 dodecanedioic acid or dimer acid, thus improving the cost of the electrolyte is improved over use of branched chain dicarboxylic acids, while the use of the hydrotropic agent maintains solubility at acceptable temperatures.
