Abstract

Rechargeable battery cells are provided in which electrolyte comprises SO2 and a conductive salt, wherein upon discharge a reaction product is produced at the positive electrode. The rechargeable battery cells can comprise carbon and a conducting element having a three-dimensional porous metal structure, and can include optional components such as a metal oxide that catalyzes at least one reduction reaction at the cathode upon discharge and/or a metal halide. Methods of making and using such rechargeable battery cells are provided.
