Jahn‐Teller Effect in Sodium Layered Oxide Cathodes: Inducement Mechanisms, Mitigation Strategies, and Rational Utilizations

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 2, 2025

Abstract The sodium‐layered transition metal oxides (Na x TMO 2 ) are regarded as the promising cathode for sodium‐ion batteries (SIBs) relying on their high theory capacity and cost‐effectiveness. Nevertheless, intrinsic lattice distortions caused by Jahn‐Teller active ions significantly degrade structural stability of Na , generally resulting in unsatisfactory electrochemical properties. In this review, begins introducing inducement mechanisms effect (TM) ions. Subsequently, restraining strategies well corresponding using element doping/substitutions, surface reconstructions, polyphase symbiosis, TM/oxygen/Na + vacancy manipulations summarized detail. Specifically, influences such mitigation deformation properties, phase evolution behaviors, TM dissolution characteristics, crystal comprehensively discussed. Furthermore, sensible utilization distortion is to build cathodes with and/or repaid ion transport kinetics well. end, challenges faced amelioration methods overviewed put forward research directions future trenchantly constrain 6 octahedron deformation. This work will provide more perceptions further studies SIBs.

Data Mining and Machine Learning Analysis to Find Polymers for Electronic and Photovoltaics Applications: A Goal to Achieve Higher Dielectric Constant

Advanced Theory and Simulations, Год журнала: 2025, Номер unknown

Опубликована: Май 3, 2025

Abstract The discovery of polymers with high dielectric constants is significant interest for advanced electronic applications, such as capacitors, flexible electronics, and energy storage devices. In this study, data mining machine learning (ML) techniques are applied to identify superior constant. Molecular descriptors calculated. These used train several models, including linear regression, gradient booting histgradient boosting bagging decision tree random forest regression. By employing cross‐validation hyperparameter tuning, best model optimized robust predictive performance. A database 10k generated their constant predicted ML model. Thirty higher values selected. This work demonstrates the power data‐driven approaches in accelerating high‐performance applications.

Sodiophilic Zn‐Diamane Ion Rectification Layer Modulated Polypropylene Separators Enable Dendrite‐Free Sodium Metal Batteries

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 26, 2024

Abstract Sodium (Na) metal is regarded as an ideal anode for sodium batteries (SMBs) due to its high theoretical specific capacity and low electrochemical potential. However, utilization still restricted by the notorious dendrites unstable solid electrolyte interface (SEI). Herein, a zinc nanoparticle decorated 2D diamond (diamane) modulated commercial polypropylene (Zn‐diamane/PP) separator dedicated mitigating these issues longevity of anodes. Interestingly, sodiophilic Zn‐diamane/PP significantly accelerates ion mobilization promotes uniform flux, thus effectively preventing dendrite growth enhancing stability SEI layer. A Na||Na symmetric cell with demonstrates prolonged lifespan exceeding 5000 h at 1 mA cm −2 mAh . Notably, it sustains >1000 ultra‐high current density 25 The dendrite‐free deposition morphology formation inorganic‐rich inner layer have been investigated through comprehensive characterizations calculations analysis. Furthermore, full comprising Na 3 V 2 (PO 4 ) @C cathode, separator, demonstrate reversible 90 g −1 over 500 cycles. These results potential long‐cycle SMBs.
