SBIR Phase II: Improved Electrodes for Capacitive Deionization

这个小企业创新研究（SBIR）第二阶段项目将开发用于电容去离子的改进的单片碳电极。电容去离子技术是一种新型的海水和微咸水净化技术。在这个过程中，在两个多孔碳电极之间施加恒定电压，可溶性盐被收集在它们的表面上，从而净化水。CDT的运行成本大约是目前首选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（无论是在美国和世界范围内）将受益于一个廉价的方法，生产饮用水从大量现有储备的苦咸水（盐水）。 廉价的中孔碳电极也可用于工业过程如锅炉进料的电容去离子，以及用于电能储存，如电容储能。

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.
