Abstract
A separator/electrolyte combination for nonaqueous cells in which the electrolyte comprises a solute dissolved in a dioxolane and acyclic ether-based solvent, such as 1,2-dimethoxyethane, and the separator has a pore size between 0.005 and 5 microns, a porosity between 30% and 70%, a resistance between 2 and 15 ohm-cm.sup.2, and a tortuosity of less than 2.5.
