Inside Back Cover: LEGO‐Like Granular‐Electrode Capacitive Deionization with Ultrahigh Mass Loading for Ultrafast Electrochemical Ion Capture

By assembling carbon granular electrodes (GEs) into a building block-like architecture, membrane-free granular-electrode capacitive deionization achieves ultrahigh mass loading while preserving short ion-transport paths. Forced convection then drives the ion-entrainment effect, renewing ions in both the inter-GE space and accessible intra-GE domain. This improved ion transport mitigates concentration polarization and sustains rapid electrochemical ion capture under high areal flux.
