However, developing electrolytes that combine high ionic conductivity with low-overpotential Mn plating/stripping remains challenging because of the trade-off between salt dissociation and desolvation. Herein, we propose a weakly coordinating electrolyte, Mn[B(HFIP)4]2 (HFIP: hexafluoroisopropyl), for advanced MnMBs. The [B(HFIP)4]– anion, featuring full electron delocalization and steric hindrance, promotes complete salt dissociation in low-dielectric-constant ethers, yielding a pure ether-coordinated Mn2+ electrolyte with high ionic conductivity (4.7–8.5 mS/cm at 20 °C) and a wide electrochemical window (>3 V). Weak ether-Mn2+ coordination facilitates desolvation, affording a record-low Mn plating/stripping overpotential (<100 mV at 0.5 mA/cm2) and dendrite-free 3D growth. Coupling Mn anodes with polytriphenylamine or activated carbon cathodes enables quick-charge full cells, demonstrating the potential of anion engineering for high-performance multivalent metal batteries.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"11 10","pages":"6776–6782"},"PeriodicalIF":17.5,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908742","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}

Here, we integrate operando synchrotron X-ray diffraction (sXRD) with electrode-level transmission X-ray microscopy (TXM) to quantitatively resolve how degradation redistributes lithium accessibility in Ni-rich NCA cathodes. Using a 26-state deconvolution framework, we show that degraded electrodes exhibit nonmonotonic Li-content population evolution: delithiation kinetics are initially suppressed, transiently synchronized, and ultimately diverge, leaving ∼7% discharge-like states and ∼13% intermediate Li-content states at the end of charge. Spatially resolved TXM reveals that this divergence originates from size-dependent accessibility constraints—large particles develop persistent intra-particle state-of-charge gradients, while small particles exhibit pronounced inter-particle disparity.

Although temperature is known to influence perovskite film formation, its role in driving asynchronous crystallization between I-rich and Br-rich domains—and thus the extent of phase segregation—remains insufficiently understood. Here, we reveal that substrate temperature critically regulates these asynchronous crystallization pathways and propose an additive-engineering strategy to overcome this bottleneck. By introducing 2-mercapto-4-(trifluoromethyl) pyrimidine (2-MTP), the strong PbX2 coordination regulates DMSO–PbX2 intermediates, substantially broadening the processing temperature window. This controlled coordination modulates precursor conversion kinetics, mitigates asynchronous halide-rich domains crystallization, and effectively suppresses phase segregation in wide-bandgap perovskite films. As a result, 2-MTP-modified wide-bandgap devices achieve PCEs of 23.79% (1.67 eV; certified 23.02%) and 19.81% (1.84 eV).

Over 0–70 MPa, increasing pressure enhances capacity but induces a nonmonotonic thermal response governed by the balance between reduced heat generation and extended discharge duration. Pressure consistently improves thermal efficiency by lowering the heat-to-capacity ratio. Incorporating a self-heating onset criterion, we quantify thermal runaway risk and identify performance-safety trade-offs that evolve with pressure, C-rate, and cathode thickness.
