Abstract
Problems associated with voltage reversal hazards in high energy density non-aqueous electrochemical cells are prevented for all except extremely high discharge rates by the provision of a safety separator which is sufficiently porous to allow normal cell operation in the forward direction but which prevents voltage reversal in all but the most extreme cases. The separator may take the form of a thin sheet of ceramic material which need not contact either the anode or the cathode but which forms an ion-permeable mechanical barrier separating the electrodes while allowing normal cell operation.
