Strongly coordinating solvents dissolve LiNO₃ but often intensify parasitic reactions with reactive Li metal. Here, we report a LiNO₃–N,N-dimethylacetamide (DMAc) synergistically regulated localized high-concentration electrolyte (LNDT) that reconciles salt dissolution with interfacial stability. In LNDT, DMAc enables LiNO₃ to serve as the primary lithium salt, while extensive incorporation of NO₃^- into the Li⁺ solvation sheath weakens DMAc–Li⁺ coordination and redirects interfacial reduction from solvent decomposition toward nitrate-derived reactions. This nitrate-rich solvation chemistry generates a gradient inorganic-rich SEI composed of Li₃N/LiN_xO_y, Li₂O, and LiF on Li metal, together with an ultrathin, uniform 1.6–1.9 nm CEI on LFP. The resulting dual-interphase stabilization improves Li plating/stripping reversibility, interfacial kinetics, and deposition uniformity. Consequently, Li||LFP cells retain 80.4% of their capacity after 1100 cycles at 1 C and 85.8% after 500 cycles at 3 C, while supporting high-loading LFP cathodes and thin Li-metal anodes.

The complex interplay between particle microstructure, crystallographic characteristics, and chemo-mechanical responses makes it challenging to predict and regulate particle failure. Here, we develop a particle-scale multiphysics framework to interpret intergranular cracking in realistic Ni-rich layered cathode particles, incorporating secondary particle morphologies and crystallographic orientations extracted from electron backscatter diffraction (EBSD). The framework integrates EBSD-resolved particle morphology and crystallographic orientation with orientation-dependent lithium transport, state of charge (SOC)-dependent diffusivity, and phase transition induced lattice evolution. Simulations reveal a transition in lithium-ion transport, from crystallographic orientation-dominated to diffusivity-controlled behavior as charging proceeds. Most intergranular cracks are triggered by abrupt <em>c</em>-axis contraction during the H2-H3 phase transition, further amplified by grain boundary misorientation. The model also captures dynamic crack opening-closure behavior during charging, consistent with in-situ observations. Guided by these insights, an orientation-regulation strategy is proposed to reduce the grain boundary misorientation, decreasing intergranular damage from 17.8 % to 7.1 %. Additionally, regulation of phase-transition behavior, lithium-ion diffusivity, and charging rate within the phase-transition regime provides effective pathways for mitigating intergranular damage, highlighting the critical role of crystallographic characteristics in particle design and operational optimization. This work establishes a mechanism-informed framework linking realistic microstructure, crystallographic characteristics, chemo-mechanical responses, and damage mitigation strategies, providing physical insights for the design of durable Ni-rich cathodes.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"91 ","pages":"Article 105554"},"PeriodicalIF":19.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149084625","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}

Herein, we construct a homogeneous organic-inorganic hybrid solid electrolyte interphase (H-SEI) network throughout the μSi electrode to enable confined electrochemical sintering via interphase engineering. Unlike conventional gradient SEI architectures, the interconnected H-SEI network simultaneously integrates high mechanical modulus and is proposed to promote interfacial interactions with both silicon and sulfide solid electrolyte. The homogeneous interphase reduces the formation of high-volume-expansion crystalline Li₁₅Si₄, redistributes lithiation-induced stress, and confines electrochemical sintering at the microparticle scale, preventing its propagation across the electrode. Meanwhile, the uniformly distributed organic components maintain intimate and stable Si/LPSCl contact during long-term electrochemical cycling. Benefiting from the synergistic regulation of electrochemical sintering and interfacial stability, the H-SEI-modified μSi electrode delivers a high areal capacity of 2.15 mAh cm^-2, ultralong cycling stability over 1400 cycles with an ultralow average capacity decay rate of 0.032% per cycle, and excellent rate capability of 958 mAh g^-1 at 8.75 A g^-1.

Here, we propose a coordination-engineered low-concentration electrolyte (CE-LCEs) based on solvation-network regulation to simultaneously enhance transport and interfacial stability. Combined experiments and theoretical calculations reveal the regulatory mechanism of CE-LCEs. Multicomponent ether solvents disrupt molecular ordering, increasing structural disorder and lowering migration activation energy across a wide temperature range. Meanwhile, a weakly solvating ether reconstructs the solvent network, reduces coordination solvent density, and breaks rigid solvation configurations. This regulation transitions the coordination structure from “solvent-dominated coordination” to “anion-participating coordination”. As a result, the electrolyte maintains good fluidity at −50°C and delivers a high ionic conductivity of 2.07 mS cm⁻¹, together with a low migration activation energy and excellent stability from −50 to 60°C.

However, their practical application remains limited by polysulfide shuttling, sluggish sulfur redox kinetics, and kinetic barriers associated with Li₂S nucleation and decomposition. Conventional strategies primarily rely on regulating material composition and structure, whereas the dynamic evolution of charge, orbital, and spin states during sulfur conversion has received comparatively less attention. Electromagnetic-field regulation provides an emerging route to directly influence these electronic degrees of freedom and thereby modulate reaction kinetics. This review discusses the fundamental mechanisms by which electric and magnetic fields regulate sulfur redox chemistry in LSBs. Electric-field effects are considered in terms of interfacial charge redistribution, built-in electric fields (BIEFs), ion migration, and field-induced modulation of electronic states, with particular attention to orbital polarization and energy-level changes associated with the Stark effect. Magnetic-field regulation is discussed from the complementary perspectives of mass transport and electronic spin, including magnetohydrodynamic effects, magnetic ordering, spin polarization, and Zeeman-induced changes in electronic states. Representative studies are used to illustrate how these effects influence polysulfide adsorption and conversion, Li⁺ transport, and Li₂S nucleation, growth, and decomposition. Finally, we identify the major challenges in establishing quantitative field-electronic-state-kinetics relationships and highlight opportunities for designing materials with intrinsic electric and magnetic functionalities.

This concept has been extended from lithium to sodium, potassium, and zinc batteries, offering opportunities for both high energy density and resource-abundant chemistries. However, their practical development is hindered by low Coulombic efficiency, unstable interfaces, nonuniform metal deposition, and rapid capacity decay. These failures arise from the coupled constraints of zero excess metal inventory, hostless metal deposition, and dynamic interface reconstruction. In this review, we establish a spatiotemporal framework to understand and regulate anode-free metal batteries. The temporal degradation chain is first divided into initial nucleation, repeated plating and stripping, and end-of-life dead metal accumulation. Key descriptors such as nucleation overpotential, metal affinity, ion transport limitation, SEI fracture, tortuosity, and active-metal inventory loss are discussed. Spatial regulation strategies are then summarized according to their dominant functions at different failure stages, including current collector modification, artificial interphase engineering, electrolyte and solvation design, and solid-state electrolyte development.
