摘要：With the large-scale exploitation of marine resources, capacitive deionization (CDI) technology has received widespread attention in marine resource utilization due to its simple structure, high efficiency and low cost. However, the traditional two-dimensional thick electrodes suffer from complex ion transport paths, low diffusion efficiency and susceptibility to fracture, which result in low areal desalination capacity and poor mechanical properties. Herein, we developed a new method for preparing 3D printing self-healing thick electrodes by surface etching and in-situ chemical cross-linking strategies using direct ink writing-based 3D printing technology. The electrodes exhibit a mass loading of active materials (48 mg cm(-2)) and impressive areal desalination capacity (0.69 mg cm(-2)) and strain (similar to 30 %), which exceeds previously reported capacitive deionization techniques. It is noteworthy that an oceanic high-flow application scenario was simulated, which demonstrates the prospect of 3D-printed self-healing thick electrodes with long-term stable operation at high flow rates (600 mL min(- 1)). This enhancement is attributed to the efficient design of the electrodes, which have micro- and nanopores in the three dimensional electrodes that enhance ion transport and reaction kinetics. This work demonstrates an innovative approach to fabricating high-performance CDI electrodes, which is important for advancing the practical applications of energy storage and conversion systems.
