Abstract: A lithium ion mixed conduction membrane includes an optional polymeric binder and a partially lithiated ion conductive material having lithium ion conductivity and electrical conductivity dispersed within the polymeric binder that is capable of improving the performance and cycle life of lithium-sulfur rechargeable batteries and other batteries exhibiting the polysulfide shuttle. One or more lithium ion conduction membranes are placed between the positive and negative electrodes, or adjacent to the negative electrode of a battery and in particular, of a lithium sulfur battery.
