Abstract Electrochemical desalination technologies such as capacitive deionization (CDI) and battery desalination (BD) are considered as promising brackish water desalination technologies because of their low energy consumption and environmental friendliness. However, it is a still challenge to develop an efficient way to deionize highly concentrated salt water using these technologies due to the limited desalination capacity. Here, we demonstrate how a system consisting of anion selective two-phase reaction battery electrodes combined with a cation exchange membrane shows a much higher capacity (approx. 85 mg g−1) along with remarkable salt removal efficiency (80%) while the cell voltage is still low (0.2 V). Moreover, with this system, it is possible to operate with high currents (100 A m−2) that are an order of magnitude higher than previous battery desalination systems.

使用银和氯化银电极的高性能电化学盐水淡化

摘要 电容去离子（CDI）和电池脱盐（BD）等电化学脱盐技术因其低能耗和环境友好而被认为是有前景的苦咸水脱盐技术。然而，由于脱盐能力有限，使用这些技术开发一种有效的去离子高浓度盐水的方法仍然是一个挑战。在这里，我们展示了由阴离子选择性两相反应电池电极与阳离子交换膜组成的系统如何显示出更高的容量（约 85 mg g-1）以及显着的除盐效率（80%），而电池电压仍然很低 (0.2 V)。此外，有了这个系统，
