Capacitive deionization
Summer students shine in desalination research
Capacitive deionization (CDI) is an emerging class of water desalination technologies that use cyclic charging and discharging of electrodes to reduce or enrich the salinity of incoming water. The desalination characteristics of CDI are strongly influenced by the resistive components of the system. To better understand this process, a team of Lawrence Livermore National…
Size matters in ion selectivity and energy storage
While ions adsorbed on carbon electrodes can vary in size and shape, when it comes to selectivity and energy storage, size really does matter. In an effort to boost energy storage and water desalination technologies, Lawrence Livermore National Laboratory (LLNL) scientists found that capacitive performance and ion selectivity of porous carbons is controlled by a complex…
Freshening up contaminated water
Nitrate is a troublesome groundwater contaminant that is mainly caused by fertilizer runoff on farmlands. Many wells in agricultural regions exceed the EPA limit for nitrate in drinking water, and without an economical treatment option the water is unfit for potable use. But Lawrence Livermore National Laboratory (LLNL) and Stanford University researchers have developed a…
