SBIR Phase II: Improved Electrodes for Capacitive Deionization

这个小型企业创新研究(SBIR)第二阶段项目将开发用于电容去离子的改进的整体式碳电极。电容去离子技术是一种净化海水和微咸水的新方法。在这一过程中，在两个多孔碳电极之间施加恒定电压，并在其表面收集可溶性盐，从而净化水。CDT的运营成本大约是当前选择的反渗透系统的一半。获得可靠和充足的清洁水供应正在成为一个世界性的问题。从这项工作中，社会(包括美国和世界各地)将受益于一种廉价的方法，从现有的大量微咸水(咸水)储量中生产饮用水。廉价的介孔碳电极还可以用于工业过程中的电容式去离子，如锅炉给水，以及用于电能存储，如电容式能量存储。

This Small Business Innovation Research (SBIR) Phase II Project will develop improved monolithic carbon electrodes for capacitive deionization. Capacitive deionization technology (CDT) is a new method for purifying ocean and brackish well water. In this process, a constant voltage is applied between two porous carbon electrodes, and soluble salts are collected on their surface, thus purifying the water. The operating costs of CDT are roughly half those of reverse osmosis, the current system of choice. Obtaining a reliable and plentiful supply of clean water is becoming a worldwide problem. From this work, society (both in the U.S. and worldwide) will benefit from an inexpensive method of producing potable water from large existing reserves of brackish (saline) water. Inexpensive mesoporous carbon electrodes could also be used in capacitive deionization for industrial processes such as boiler feed, as well as in electrical energy storage, such as in capacitive energy storage.
