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.

Metal halide cathode with enriched conductive additive

The technology described herein provides a stand-alone intelligent battery charger and intelligent conditioner for use with a high-voltage battery, such as those used in hybrid automotive vehicles. Additionally, in various exemplary embodiments, this technology provides a system and method for validating the capacity of a high voltage battery. Other comparable uses are also contemplated herein, as will be obvious to those of ordinary skill in the art.
