Freshwater is unavailable for roughly one out of seven people worldwide. This is partially related to the fact that 97.5% of earth's water resources are saline water having high salt concentrations. Desalination processes are used to turn saline water into drinking water. An especially efficient process is called capacitive deionization (CDI), which is based on applying an electric voltage between two electrodes made of high surface area materials. The electric voltage triggers the removal of electrically-charged species, such as dissolved salts from the water, by adsorption on the electrode surface. This proposal is concerned with the establishment of a collaboration between Canadian and German researchers in order to develop novel selective CDI materials. Such selective material can find application not only in water desalination but also in decontamination of industrial sites or as an environmental-friendly method to mine lithium. The respective research will train Highly Qualified Personnel and contributes to Canada's economic future.

全世界大约七分之一的人无法获得淡水。这部分与地球水资源的97.5%是含盐量高的咸水有关。海水淡化是用来把含盐的水变成饮用水的。一个特别有效的过程被称为电容去离子（CDI），它是基于在两个高表面积材料制成的电极之间施加电压。电压触发电极表面吸附去除带电物质，如水中溶解的盐。该提案涉及建立加拿大和德国研究人员之间的合作，以开发新的选择性CDI材料。这种选择性材料不仅可以用于海水淡化，还可以用于工业场所的净化或作为一种环保的锂矿开采方法。各自的研究将培养高素质的人才，并为加拿大的经济未来做出贡献。
