    • Capacitors employing liquid or gel electrolytes have their useful lifetime significantly extended by including, in the electrolyte, a binary mixture of transition metal ion species. Each species has at least two distinct oxidation states when dissolved in the electrolyte. The interaction of the mixture of ion species reduces the potential of the cathode and maintains the potential of the cathode below the hydrogen potential to prevent the reduction of hydrogen ions and the formation of hydrogen. The binary mixture of transition metal species reduces the cathode potential by oxidation of the transition metal species at the anode and reduction of the transition metal species at the cathode. Thus, the rate of decrease in capacitance, increase in equivalent series resistance, and swelling of the capacitor are suppressed. In addition, the ratio of capacitor aging to the quantity of charge passed by the capacitor is decreased by at least a factor of two as compared to previous known extended life capacitors.
    • 使用液体或凝胶电解质的电容器通过在电解质中包括过渡金属离子种类的二元混合物而具有显着延长的其使用寿命。 当溶解在电解质中时,每种物质具有至少两种不同的氧化态。 离子物质混合物的相互作用降低了阴极的电位,并且使阴极的电位维持在氢电势以下,以防止氢离子的还原和氢的形成。 过渡金属物质的二元混合物通过阳极处的过渡金属物质的氧化和阴极处的过渡金属物质的还原来降低阴极电势。 因此,抑制了电容的减小率,等效串联电阻的增加和电容器的膨胀。 此外,与先前已知的延长寿命电容器相比,电容器老化与通过电容器的电荷量的比率减少至少两倍。

    • A computer-implemented method of solving a system optimization problem having a plurality of parameters of unknown value is comprised of randomly generating sets of values for unknown parameters w ithin an the optimization problem. A population of original candidate solutions is generated by applying an algorithm for deterministic optimization to each of the sets of values. The population of solutions is ranked. Additional candidate solutions are iteratively generated from at least certain of the solutions in the population. The validity of the additional candidate solutions is checked, and the valid additional candidate solutions are added to the population of solutions. The population of solutions is re-ranked and at least one solution from the population of solutions is output when a predetermined criterion is met whereby the values for the parameters in the output solution may be used for controlling a system.
