“…Capacitive deionization (CDI) is a water flow desalination technology without the high pressure applied [2][3][4][5]. Its advantages include high energy-efficiency, cost-effectiveness, and eco-friendliness [6,7]. When an electrical field is applied between the carbon electrodes, the ions in the salt feed are adsorbed to purify the water.…”

“…ESR reflects the combination of intrinsic electron resistance of carbon materials, ion diffusion resistance of electrolyte, and the contact resistance between electrode and electrolyte, which can be obtained by intercept of Nyquist plots with real axis at high-frequency regions. 62 ESR values are calculated to be 1.38, 1.34, 1.33, and 1.27 Ω for N-PCM-0, N-PCM-3, N-PCM-6, and N-PCM-9 electrodes, respectively. Moreover, N-PCM-9 shows the smallest semicircle value, indicating fast charge transfer in the N-PCM-9 electrode.…”

The advancement of supercapacitors (SCs) is closely bound up with the breakthrough of rational design of energy materials. Freestanding and thick carbon (FTC) materials with well-organized porous structure is promising SC electrode delivering high areal capacitive performance. However, controllable and sustainable fabrication of such FTC electrode is still of great challenges. Inspired by natural honeycombs with cross-linked multichannel structure, herein, an innovative molecular-cooperative-interaction strategy is elaborately provided to realize honeycomb-like FTC electrodes. The nitrogen-doped porous carbon monolith (N-PCM) is obtained with advantages of interconnect pore structure and abundant nitrogen doping. Such strategy is based on naturally abundant molecular precursors, and free of pore-templates, expensive polymerization catalyst, and dangerous reaction solvent, rendering it a sustainable and cost-effective process. Systematic control experiments reveal that strong interactions among molecular precursors promise the structural stability of N-PCM during carbonization, and rational selection of molecular precursors with chemical blowing features is key step for well-developed honeycomb-like pore structure. Interestingly, the optimized sample exhibits hierarchical pore structure with specific surface area of 626.4 m 2 g À1 and rational N-doping of 7.01 wt%. The derived SC electrode with high mass loading of 40.1 mg cm À2 shows an excellent areal capacitance of 3621 mF cm À2 at 1 mA cm À2 and good rate performance with 2920 mF cm À2 at 25 mA cm À2 . Moreover, the constructed aqueous symmetric SC and quasi-solid-state SC produce high energy densities of 0.32 and 0.27 mWh cm À2 , respectively. We believe that such a composition/microstructure controllable method can promote the fabrication and development of other thick electrodes for energy storage devices.

“…These include activated-, templated-and biomass-derived carbons, graphene-based materials, carbon nanofibers, and carbon nanotubes [32][33][34][35][36]. In particular, activated carbons (ACs) have been frequently used in CDI because of their low cost, abundance, good electrical conductivity, and high porosity for ion adsorption [37][38][39][40][41]. However, due to the dominant micropores (<2 nm) and severe pore tortuosity, commercial ACs usually show low SAC [42,43], largely limiting their practical implementation for CDI.…”
