Abstract
A rechargeable metal halide battery shows increased metal halide utilization with the introduction of electronegative heteroatom-enriched conductive additives into a metal halide cathode incorporated into an electrically conductive material. The electronegative heteroatom-enriched conductive additives include nitrogen-doped carbon, such as nitrogen-doped single layer graphene, and oxygen-enriched carbon, such as acid-treated carbon black. The modified batteries utilize 20-30% more metal halide than unmodified batteries resulting in enhanced specific capacity and energy density.
