Abstract Nowadays, capacitive deionization (CDI) has emerged as a prominent technology in the desalination field, typically utilizing porous carbons electrodes. However, precise significance of electrode properties and operational conditions shaping performance remains blurry, necessitating numerous time‐consuming resource‐intensive CDI experiments. Machine learning (ML) presents an emerging solution, offering prospect predicting with minimal investment material synthesis testing. Herein, four ML models are used for carbons. Among them, gradient boosting model delivers best on test set low root mean square error values 2.13 mg g −1 0.073 min capacity rate, respectively. Furthermore, SHapley Additive exPlanations is introduced to analyze conditions. It highlights that electrolyte concentration specific surface area exert substantially more influential role determining compared other features. Ultimately, experimental validation employing metal–organic frameworks‐derived biomass‐derived electrodes conducted affirm prediction accuracy models. This study pioneers techniques performance, compelling strategy advancing technology.

Abstract Hybrid capacitive deionization (HCDI) emerges as a burgeoning electrochemical desalination technology due to the utilization of profitable pseudocapacitive reactions. Although tunable organic compounds are potential faradaic electrode materials, their insufficient active sites and high water‐solubility restrict practical HCDI applications. Herein, polymer (PNDS) is proposed with diverse redox‐active for deionization. The pronounced molecular aromaticity strong π‐electron delocalization not only endow PNDS framework rigidity, but refine its electronic structure bolster redox activity electron affinity. As an material, demonstrates substantial capacitance 390 F g −1 sustains long‐term stability at 96.3% after 5000 cycles, surpassing reported Na + ‐capturing electrodes. In‐operando monitoring techniques theoretical calculations reveal efficient capture C═N C═O within during repeated electrosorption processes. conceptual demonstration, high‐performance device equipped exhibits impressive salt removal capacity (66.4 mg ), rapid rate (2.2 min ) stable regeneration property. More importantly, integrated system engineered rapidly repeatedly treat saltwater resources human consumption agricultural irrigation, highlighting promising prospects high‐efficiency
