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.

Abstract: In a method for operating an internal combustion engine of a motor vehicle having an automatic transmission, a torque generated by the internal combustion engine is reduced as a function of an operating state of a drive train of the motor vehicle. As a function of an excess of combustion air occurring when the torque is reduced and supplied to the internal combustion engine by an exhaust gas turbocharger, fuel combustion efficiency in at least one combustion chamber of the internal combustion engine, which is related to the torque generated by the combustion chamber, is reduced. The combustion efficiency is reduced by at least one late post-injection of fuel into the at least one combustion chamber of the internal combustion engine.
