Title: Reactive separator for a metal-ion battery

Abstract

A reactive separator is provided for a metal-ion battery. The reactive separator is made up of a reactive layer that is chemically reactive to alkali or alkaline earth metals, and has a first side and a second side. A first non-reactive layer, chemically non-reactive with alkali or alkaline earth metals, is adjacent to the reactive layer first side. A second non-reactive layer, also chemically non-reactive with alkali or alkaline earth metals, is adjacent to the reactive layer second side. More explicitly, the first and second non-reactive layers are defined as having less than 5 percent by weight (wt %) of materials able to participate in electrochemical reactions with alkali or alkaline earth metals. The reactive layer may be formed as a porous membrane embedded with reactive components, where the porous membrane is carbon or a porous polymer. Alternatively, the reactive layer is formed as a polymer gel embedded with reactive components.
