Although conventional photolithography offers high feature resolution, it involves a fundamental trade-off among spatial resolution, ionic capacitance, and stability in the electrolyte. Here we report an ion compensation-assisted photolithography (ICAP) strategy that yields electrolyte micro-patterns combining high precision, high capacitance and high stability. A molecularly engineered electrolyte forms, under UV exposure, a physicochemical dual cross-linked network with strong solvent resistance and hydrophobicity, which suppresses swelling during both aqueous development and the subsequent ion-compensation step, preserving pattern fidelity. Ion compensation then restores and enhances the mobile-ion content, increasing areal capacitance. The resulting electrolytes achieve a record 2 μm resolution, 15.6 μF cm<sup>−2</sup> capacitance, and strong thermal stability from − 50 to 200 °C. Integrated into OECTs, the ICAP-patterned electrolytes suppress crosstalk by 97.6% and boost on/off ratios by 325%, reducing parasitic coupling by more than 40 times compared to unpatterned arrays. The method is compatible with <i>p</i>-type and <i>n</i>-type organic semiconductors and inorganic oxides, providing a versatile route to scalable neuromorphic circuits and advanced bioelectronics. \u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02288-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148428710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the surface-originated degradations and local structure rearrangement incur severe capacity and voltage fading, which fundamentally impedes the practical deployment of LLOs. Here, we report a pre-constructed multifunctional carbon/fluorine-rich artificial cathode electrolyte interface (CEI) layer via a facile thermal treatment. This surface integrated layer, with high-voltage tolerance and amorphous features, is designed to mitigate surface-originated parasitic reactions and phase transformations induced by electrochemistry. Multiscale characterizations reveal that the artificial CEI layer exhibits excellent interfacial compatibility with both the LLO cathode and the electrolyte system, ensuring highly reversible anionic redox and low activation barrier for Li<sup>+</sup> transport. Profiting from this architecture, remarkable cycling stability is achieved including 90.6% retention after 300 cycles in half cell, along with high energy efficiency and markedly alleviated voltage fading. More importantly, the artificial CEI layer demonstrates a distinct depolarization effect, which almost completely prevents the rise in charging voltage upon cycling. This work provides valuable insights into surficial/interfacial modulations and broadens research directions for designing high-voltage cathodes with more durable interphases for next-generation batteries.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02276-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148416239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, this study proposes an innovative design strategy combining interfacial bridging engineering and physical encapsulation to construct advanced multifunctional composite phase change materials (PCMs). A nanoparticle-bridged 3D interpenetrating phonon network is constructed via in-situ growth of CuS nanoparticles on layered MXene, creating abundant interfacial sites for polyethylene glycol (PEG) adsorption and efficient electron transport channels for electromagnetic loss. The resulting PEG-MXene@CuS composite PCMs achieve an exceptional photothermal conversion efficiency of 94.5% (100 mW cm<sup>−2</sup>), enabled by broadband absorption of MXene nanosheets and plasmonic effect of CuS nanoparticles. In photoresponsive thermoelectric cogeneration system, PEG-MXene@CuS serves as a heat source to drive thermoelectric module through the Seebeck effect, yielding a stable power output of 21.7 W m<sup>−2</sup> (100 mW cm<sup>−2</sup>), with PEG effectively buffering thermal fluctuations. Moreover, MXene@CuS heterointerface and 3D conductive network endow PEG-MXene@CuS with superior microwave absorption, a minimum reflection loss of − 55.5 dB and an effective bandwidth of 5.27 GHz. This design concept provides important insights into designing next‑generation multifunctional PCMs with promising applications in intelligent thermal management, thermoelectric cogeneration, and electromagnetic protection.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02277-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148393485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
