Advancing electrode materials with high adsorption capacity and fast rate is crucial for seawater desalination in capacitive deionization (CDI). Here, we propose a highly oriented, densified graphene (HODG) characterized by its ordered/short ion transport channels, abundant oxygen functional groups, packing density (1.374 g cm–3), large specific surface area (543.72 m2 g–1), facilitating exceptional diffusion ultrahigh volumetric capacity. HODG delivers capacitance of 308 F cm–3 at 1 A g–1, record-high salt (v-SAC) 57.70 mg rapid 1.92 min–1 1.2 V 1000 L–1 NaCl. Even after 50 cycles adsorption–desorption, it can still retain 91.36% initial This proposed design strategy offers new avenue the rational optimization architectures, boosting development high-performance CDI toward practical applications.

Porous carbon electrode materials were prepared by carbonization and alkali activation from three natural porous biomasses, lotus petiole (LP), sunflower plate (SP), seedpod (LS). The pore structure, surface characteristics, electrochemical properties of the activated biochars investigated related to their CDI performance. results indicated that hydrophilic negatively charged, with a high specific area an abundance micropores. Due best wettability, highest capacitance, shortest charge-discharge time, petiole-based biochar (LPCK) had electrosorption capacity 8.67 mg·g−1 faster desalination rate 0.24 mg·g−1·min−1. Cyclic voltammetry adsorption kinetics indicate double-layer electrostatic mechanism dominated processes biochars. use biomass wastes provides low-cost, eco-friendly, sustainable for development electrodes.

Layered Double Oxide as a Cl⁻ Selective Anode for High-Performance Electrochemical Lithium Extraction

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(31), С. 11692 - 11704

Опубликована: Июль 24, 2024

The widespread application of lithium-ion batteries and the rapid development electric vehicles have increased demand for lithium resources. Electrochemical extraction has been proven to be an effective method Li+ recovery from brine due its environmental friendliness excellent selectivity. In a conventional configuration, LiMn2O4 (LMO)||activated carbon (AC)/anion exchange membrane (AEM), AEM is essential avoid adsorption onto AC anode during Cl− desorbing. Here, we propose that layered double oxide (LDO) serves as material with high CoAl-LDO was synthesized by one-pot hydrothermal method, followed heat treatment, used LMO cathode (LMO||CoAl-LDO). intercalation capacity LMO||CoAl-LDO reached 1.35 mmol g−1 at 1.2 V maximum rate 0.57 min−1 retention 70.83% after 20 cycles, higher than those LMO||AC/AEM (1.12 g−1, 0.37 min−1, 35.48%, respectively). Moreover, selectivity in Li+/Mg2+ binary solution (1:5) investigated, showing separation factor (2.67) close (2.98). situ Raman characterization conducted, good were induced anion mechanism CoAl-LDO. addition, coated further enhanced capacity, which assisted performance 1.80 capacity. We believe promising electrochemical extraction.
