However, the mainstream graphite anode encounters significant challenges in fast-charging scenarios, including capacity decay and shortened lifespan caused by the sluggish lithiation kinetics and unstable solid electrolyte interphase. Herein, the kilogram-level scalable production of ultrafast-charging anode (C@MEG) consisting of micro-expanded graphite coated by an ultrathin disordered carbon layer (5 nm) is reported, which simultaneously compensates for the conventional limitation of internal lithium diffusion kinetics and reconfigures the external electrode-electrolyte interface. This uniqueness endows rapid surface-to-bulk lithium transport, with minimized electrode polarization, enhanced pseudocapacitive behavior, and reduced interface impedance. At an ultrafast-charging rate of 10 C, this Li||C@MEG cell exhibits an ultrahigh capacity of 157 mAh g-1, superior to pristine graphite (71 mAh g-1) and previously reported graphite anodes. Moreover, this assembled 1 Ah-level C@MEG||LiCoO2 pouch battery delivers remarkable fast-charging cyclability, showcasing 92% capacity retention after 1000 cycles under 3 A, together with high power density around 1500 W kg-1 under 10 A, corresponding to a short charging time of only 4.2 min, demonstrative of applicability.

Through the protonation of tertiary amine sites and precise structural engineering of side chains within the COF framework, well-defined transport channels are created to enhance water and oxygen mass transfer. The results demonstrate that P-rCOF-C4 significantly improves the catalytic performance of commercial Pt/C catalysts, with a half-wave potential 37 mV higher than Nafion. Furthermore, a PEMFC incorporating P-rCOF-C4 as an ionomer binder achieves a peak power density of 2.40 W cm-2 at 0.1 mg cm-2 catalyst loading, a 1.5 fold increase over Nafion.

However, the intrinsic insulating nature of Li2O2 fundamentally restricts reaction kinetics, posing a core challenge to practical applications. Here, it is demonstrate that the insulating properties of Li2O2 can be effectively improved by photoexcitation, attributed to the generation of photo-induced charge carriers. It is inspired to develop photo-assisted Li-O2 batteries featuring Z-type photocathode@Li2O2 heterojunction, which serves as a charge modulation channel to regulate carrier dynamics through photocathode modifications. By employing edge-dislocated WO3 as the photocathode, sustained growth of Li2O2 films is observed with a thickness >18 µm, which is 2-3 orders of magnitude higher than typically reported values. Benefiting from the enhanced exciton dissociation of Li2O2 and improved oxidative capability of photocathode, the battery delivers an ultra-high discharge capacity of 31 800 mAh g-1 under a current density of 100 mA g-1 and a light-induced temperature of ≈60 °C.

While conventional merocyanine photoacids offer pH modulability, their practical implementation is fundamentally constrained by aqueous dissolution and laborious regeneration. Here, a transformative strategy is reported through the covalent integration of merocyanine photoacids into hydrophilic polymer networks to construct regenerative photoacid matrices, which stably retain protons in the dark and spatiotemporally liberate them upon illumination. The photoacid matrix overcomes solubility constraints through adjustable merocyanine grafting density while simultaneously enhancing alkaline stability, thereby enabling shape-governed, diffusion-controlled proton release kinetics. The universality of this approach has been extensively verified in multiple polymer matrices with variable chemical compositions. Upon straightforward separation and acidic regeneration in the dark, the recovered matrices sustainably maintain robust photoactivated proton release capability. This not only enables programmable control over acid-base indicator discoloration but also guides hierarchical self-assembly of arylazopyrazole-based hydrogelators, yielding 3D supramolecular gel architectures with tailored complexity. Furthermore, spatially controlled directional proton liberation are established through synergistically addressing negative phototropic deformation within a low-density crosslinked photoacid matrix. This work creates a new paradigm for spatiotemporal pH manipulation in the development of autonomous materials through regenerative photoacid matrices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"94 1","pages":"e08265"},"PeriodicalIF":29.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669556","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}

Their energy density can further be significantly improved by using Li metal anodes; however, Li metal suffers from the critical challenges of unstable solid-electrolyte interphase (SEI) along with uncontrollable dendritic Li growth. Here, a universal electrolyte design principle is proposed and demonstrated by using suspension electrolytes with charged additives. The solvation structure of Li ions can be regulated, as negatively charged additives show strong electrostatic interaction with Li ions, leaving them weakly solvated in the electrolyte. Moreover, negatively charged additives carrying Li ions can be locally concentrated at the surface of the Li metal, enhancing their ability to regulate solvation and improve interfacial mobility, beneficial for the formation of inorganic-rich SEIs and compact Li deposition. Accordingly, Li||Li symmetric cell demonstrates >500 h stable cycling at 2 mA cm-2 and 2 mA h cm-2, and Li||LiFePO4 cell shows 97% capacity retention after 400 cycles in 1C. The universality of this design is further demonstrated in various negatively charged suspension electrolyte systems.
