Herein, we ingeniously engineer a durable interface layer on the zinc foil surface through an in-situ chemical grafting approach using silane as a molecular bridge (SG@Zn. This functionalized polysilane layer successfully welds the metallic substrate and the organic segments, fostering a highly compatible interface via robust Si-O-Zn bonds, serving as a shielding layer to protect the electrode from corrosion. The silane framework facilitates the uniform anchoring of subsequent zinc-affinitive functional groups at the molecular level, which not only brings a rapid zinc ion reaction kinetics but also ensures dual enhancement against expansion inhibition and dendrite penetration. Consequently, the symmetrical battery thus showcases superior reversibility in stripping/planting processes and demonstrates negligible voltage fluctuations at various currents and capacities. The MnO2-based full batteries maintain a capacity of 200 mAh g -1 with a negligible cyclic capacity decay rate of 0.017% over 700 cycles at 1 C.

Compared to conventional lithium-ion batteries, SSBs offer significant advantages, including enhanced safety, higher energy density, and extended cycle life. However, a major challenge lies in identifying solid electrolyte interphase (SEI) materials with high shear modulus (Gs) and exceptional ion transport properties to prevent lithium dendrite formation and improve overall battery performance. Here, we introduce an innovative approach utilizing lateral transfer learning to accelerate the discovery of high-performance SEI materials. Traditional machine learning models often require large datasets, which are typically unavailable for specialized material properties like Gs. To address this, we applied lateral transfer learning, transferring knowledge from models trained on larger datasets (bandgap data) to predict Gs within smaller datasets. By leveraging Crystal Graph Convolutional Neural Networks (CGCNN), the method effectively captures structural relationships at the atomic level, achieving a Gs prediction accuracy of 90%, ultimately identifying 12 promising SEI candidates. This sophisticated methodology not only accelerates material discovery but also opens new pathways for deploying artificial intelligence in advanced energy materials, driving progress toward safer and more efficient SSBs.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"42 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142967956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, we report a regenerative redox mediator strategy, targeting the operation window of the lithium sulfur batteries. The redox mediator can spontaneously consume the dead lithium on the anode, then be re-oxidized on the cathode through electrochemical process. Based on this design, the lithium sulfur pouch cell can be fully charged at 1C for more than 140 cycles. Moreover, the regeneration mechanism is studied by in situ UV-vis spectroscopy.

MSA can restructure the solvation structure of Zn2+ ions and guide the organized deposition of zinc (Zn) along the (100) crystal plane. A crystal plane shielding effect has been proposed, which accelerates the plating-stripping processes, enhances overall stability and suppresses Zn dendrite formation. Consequently, incorporating MSA expands the current density range and enhances the practical usability of AZIBs under extreme conditions. As a result, Zn||Zn symmetric cells demonstrate an exceptional cycling life of 300 h at 80 mA/cm² and 1 mAh/cm², with an impressive 24,000 cycles. The MnO2||Zn full cells utilizing the MSA-containing electrolyte demonstrate exceptional capacity retention of 85.4% after 3,000 cycles at 0.5 A/g.

In response, our work proposes a charge/discharge protocol that in-situ accurately customizes an inner-LiF-rich bilayer SEI in a commercial carbonate electrolyte without introducing additional functional additives to reduce the energy barrier for Li+ migration and thus enable fast-charging capabilities for Gr anode. Moreover, our study reveals strong structure-dependent properties of the SEI on the Gr, including interface affinity, Li+ transport, and electrical insulation, which helps to design high-ion-conductivity and stable SEI. As a result, the in-situ electrochemical customization of the inner-LiF-rich bilayer SEI significantly increases the cycling stability and rate performance of Gr anode, maintaining a high capacity retention of 70.6% after 1000 cycles at a high rate of 5 C. Moreover, the LiNi0.6Co0.2Mn0.2O2 (NCM622)||Gr pouch cell utilizing the new formation protocol demonstrates a 9.5% increase in capacity retention compared to the traditional charge/discharge formation protocol.
