CDI ragone plot as a functional tool to evaluate desalination performance in capacitive deionization†
Abstract
A novel concept to evaluate desalination performance in capacitive deionization (CDI) is proposed called the CDI Ragone plot. The plot can allow for intuitive acquisition of deionization capacity (mg g−1), rate (mg g−1 s−1), and time (s) and thus, will work as a functional tool to evaluate desalination performance in CDI.
