Standard rate constant, which is required to evaluate the energy efficiency, is believed to be “constant". However, there are practically dependent on the concentration of active materials. In addition, our VSSB uses slurry active material with very high concentration. In this work, the dependence of the “standard rate constant" on concentration of Vanadium ions and its effect on the energy efficiency were clarified. Standard rate constants (k0) for 1 - 5 mol dm-3 in composite of “carbon fiber - slurry active material" was evaluated. On the basis of the obtained k0 values, energy efficiencies for VRFB and VSSB were calculated. In spite that k0 decreases with increasing the concentration, energy efficiency for VSSB is not decreased because of the compensation by the large concentration.

评估能源效率所需的标准速率常数被认为是“常数”。然而，这实际上取决于活性材料的浓度。此外，我们的VSSB使用非常高浓度的浆料活性材料。在这项工作中，“标准速率常数”的依赖性的钒离子的浓度和它的能量效率的影响进行了澄清。测定了1 ~ 5 moldm ~（-3）在“碳纤维-浆料活性材料”复合体系中的标准速率常数（k_0）。在所获得的k 0值的基础上，计算VRFB和VSSB的能量效率。尽管k 0随着浓度的增加而减小，但由于大浓度的补偿，VSSB的能量效率并没有降低。
