Abstract
Novel batteries formulated with compositions comprising liquid electrolyte plasticizers having enhanced ambient temperature conductivity are provided. These plasticizers have the following general structures ##STR1## in which R.sup.a, R.sup.b, R.sup.c, X, Y, Z, .alpha., .beta., .gamma., and l are as defined herein. Novel compositions and films comprising these plasticizers are also provided.
