电容混合(CapMix)是一种利用超级电容器收集盐度梯度能量的新兴技术。这里，正电荷季铵盐聚(4-乙烯基吡啶)涂层活性碳和负电硝酸氧化活性碳被用作不对称CapMix(Asy-CapMix)的电极，使其能够在不使用外部电源和选择性膜的情况下通过四步或两步能量产生循环来产生电能。该电容器的压升为150.0 mV，平均功率密度最高可达65 mW m−2。这两个值都高于对称电极和外电源或选择性膜的电容，也好于以前的包括外电源的电容。这种优异的性能可以归因于化学修饰的活性碳电极具有高的表面电荷密度和良好的导电性，这可能为高性能Asy-CapMix电极的设计提供借鉴。
Capacitive mixing (CapMix) is an emerging technique that uses supercapacitors for harvesting salinity gradient energy. Here, positively charged quaternized poly(4-vinylpyridine) coated activated carbon and negatively charged nitric acid oxidized activated carbon are employed as electrodes for asymmetric CapMix (Asy-CapMix), enabling the production of electricity via four-step or two-step energy generation cycles without using an external power source and selective membranes. The voltage rise of this capacitor is 150.0 mV, and the average power density can reach as high as 65.0 mW m−2. Both values are higher than those of CapMix using symmetric electrodes and an external power source or selective membranes and better than those of previous Asy-CapMix, including those with external power supplies. Such superior performance can be attributed to the high surface charge density and the good conductivity of the chemically modified activated carbon electrodes, which may give insight into the design of electrodes for high performance Asy-CapMix.
