This study proposes a comprehensive integration of theoretical predictions and experimental validation, demonstrating the rationality and feasibility of the asymmetric multiple doping of Co and B in the second coordination sphere of FeN4 (Fe, Co/NCB) to facilitate *OH desorption. Density functional theory (DFT) calculations predict that the strategic coupling of Co and B effectively modulates the hybridization behavior between the 3dz2 orbital of the Fe active sites and the 2pz orbital of *OH intermediates. This interaction elevates the occupancy of the antibonding orbitals, thereby promoting *OH dissociation. Furthermore, the enhanced stability of Fe─N bonds in the Fe, Co/NCB suppresses the demetallization process of Fe active sites. Guided by theoretical predictions, a synergistic “metal substitution and spatial confinement encapsulation” strategy is developed to synthesize Fe, Co/NCB.

To enhance battery sustainability and circularity, direct recycling methods aim to recover intact cathode materials. However, end-of-life cathode materials are typically 15–20 years old and often have lower energy density compared to current cathode materials. To address this challenge, a rapid precipitation process is developed to boost energy density by converting low Ni-compositions, LiNi0.33Co0.33Mn0.33O2 (NMC111), into higher Ni-compositions (NMC622). This process forms a Ni-rich coating on cathode particles that diffuses into the core upon high-temperature relithiation, increasing compositional homogeneity. The upcycling process leverages existing infrastructure, offering low capital cost and minimal additional chemical input. Through ex situ tomographic transmission X-ray microscopy (TXM), 3D Ni:Co elemental mixing is quantified, confirming that elemental content evens at the secondary particle level with a mean NMC622 composition upon relithiation. However, elemental gradients remain in the single crystalline primary particles. Ex situ high-resolution and in situ wide-angle X-ray diffraction reveals concurrent structural changes during the relithiation process. These findings provide key insights into the structural and chemical mechanisms of elemental diffusion to obtain further improvements of increased capacity and retention through compositional conversion of cathode materials.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"34 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146324","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}

However, current SEI formation occurs predominantly during the electrochemical process, rendering the Zn anode susceptible to parasitic reactions prior to and during the SEI formation process. Herein, a spatiotemporal-orchestrated hybrid SEI is proposed, using a hydrous organic electrolyte comprising hydrated Zn(BF4)2 salt and propylene carbonate (PC) solvent. The electrolyte facilitates the initial formation of a rigid inorganic ZnF2 component during battery resting, providing immediate protection for Zn anodes upon contact with the electrolyte, followed by the generation of flexible organic species via electro-decomposition of PC molecules during battery cycling. This rigid-flexible coupled hybrid SEI is capable of accommodating substantial volume changes during Zn plating/stripping, preventing cracking and ensuring long-term stability. As a result, the Zn anode sustains a stable cycling for over 1500 h, a high Coulombic efficiency of 99.8%, and enhanced performance even in conventional aqueous electrolytes.

As a representative transition metal ion, Mn2+ features a half-filled 3d5 electron configuration that enables diverse coordination geometries and a broader scope for battery optimization. Here, the ion-specific coordination between Mn2+ and acetate ions (Ac−) to adjust the d-electron configuration of Mn2+ and induce a distorted water-deficient hydration shell is demonstrated. The coordination chemistry of Mn2+ allows Ac− to break the octahedral geometry of [Mn(H2O)6]2+ through ligand exchange, facilitating the de-solvation kinetics and interfacial transfer of Mn2+. This regulating effect is distinct from that observed in Zn2+ solvation, highlighting the ion-specific pairing resulting from the d-electron configurations of transition metals. As expected, incorporating Ac− ligands in aqueous manganese-based electrolytes enhances the Mn2+ storage performance of perylenetetracarboxylic diimide (PTCDI) anode in terms of both capacity and stability.

Binders play an essential role in maintaining electrode integrity. However, conventional binders often exhibit insufficient mechanical properties, leading to structural failure under stress. Inspired by the mussel byssus which contains metal coordination bonds to achieve toughness, this work proposes a dual-dynamic network that integrates self-healing ability and toughness through hydrogen bonds and metal coordination into a soft isoprene backbone. The extensibility of the crafted structure enables deformation exceeding 1300%, which is remarkably higher than most reported binders. Different from the self-healing binders with single reversible bonds which have limited mechanical properties, the dual-dynamic network combines rapid repair via hydrogen bonds with sufficient toughness from coordination bonds. In addition, the carboxyl groups retained during grafting provide interaction with the Si surface. Accordingly, the SiC and SiOx electrodes with as-made binder achieve good cycling stability (retention of 83.3% and 86.8% after 300 cycles, respectively). The LiPF6//SiC full cell retains 96% after 150 cycles at 0.2C, and NCM811//SiC cell achieves retention of 84.2% after 200 cycles at 0.5 C. The implementation of this self-healing binder provides a novel paradigm for rationally engineering the multi-function binders.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"46 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136982","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}

Conversely, at high temperatures, internal side reactions and phase transitions are exacerbated, which accelerates material degradation and thermal failure. These challenges limit the development and widespread adoption of ASSLBs. Therefore, expanding the operational temperature range of ASSLBs is essential for their commercial viability.

However, this high‐voltage operation intensifies oxygen redox reactions and irreversible sliding of O–Co–O slabs, which result in structural collapse and chemical instability in LCO. Herein, a local oxygen coordination optimization strategy is proposed by introducing transition metal (TM)‐O‐TM configurations to achieve reversible O1 phase transition in 4.8 V LCO. These configurations are formed by doping Ni, Fe, and Al into the lattice, where the Ni/Fe serves as pillars within Li layers, stabilizing the deep de‐intercalation structure and thus facilitating a reversible H1‐3/O1 phase transition at 4.8 V. Additionally, local oxygen environment alternation leads to an increased proportion of high‐spin state Co3+, diminishing the hybridization between the Co3+ 3d‐t2g and O 2p orbitals, thereby mitigating anion redox reactions. Consequently, lattice oxygen loss and detrimental surface phase degradation are inhibited, thereby preventing an increase in battery polarization voltage and enhancing the reversible H1‐3/O1 phase transformation. Ultimately, this significantly mitigates the accumulation of internal stress and prevents bulk failure during repeated deep (de)lithiation processes, thereby significantly enhancing the capacity retention of the optimized LCO cathode at an ultrahigh voltage of 4.8 V.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"62 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133616","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}
