Traditional energy supply strategies are unable to meet the strategic needs of long-range stealth operations and extreme environmental survival. Triboelectric nanogenerators provide a disruptive path for constructing self-sustaining military microsystems with high-efficiency and zero-power-sensing characteristics. This review establishes a comprehensive framework that systematically evaluates recent technological advances across an escalating hierarchy, encompassing individual soldier combat platforms, unmanned combat systems, strategic aerospace equipment, and special tactical scenarios. Crucially, moving beyond generic laboratory demonstrations, this review adopts a rigorous defense engineering perspective by conducting an integrated failure mode analysis to evaluate device degradation under severe battlefield stressors. Furthermore, it critically analyzes the primary engineering bottlenecks currently hindering military adoption, such as inherent impedance mismatch and scalable manufacturing barriers, and proposes targeted mitigation strategies. To systematically validate these solutions, we explicitly propose a concise evaluation framework strictly aligned with established military testing protocols. Ultimately, this review outlines several forward-looking strategic priorities, thereby constructing a highly actionable roadmap to accelerate the practical deployment of self-driven intelligent technologies.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02221-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148154791","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}

Polyanionic NASICON‐type frameworks have emerged as a compelling cathode platform due to their robust three‐dimensional Na<sup>+</sup> ions diffusion networks, strong inductive effects, and excellent thermal stability. Within this materials family, fluorophosphate NASICON cathodes offer elevated redox potentials, while targeted anion chemistry modulation provides an effective strategy to tune electronic structure, ion migration, and interfacial reactivity. Representative vanadium‐based fluorophosphate cathodes, Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>2</sub>F<sub>3</sub> (NVPF) and Na<sub>3</sub>V<sub>2</sub>O<sub>2</sub>(PO<sub>4</sub>)<sub>2</sub>F (NVOPF), exhibit closely related crystal frameworks yet display distinct sodium storage behavior and degradation characteristics under high‐voltage operation. In NVOPF, partial substitution of F<sup>−</sup> by O<sup>2−</sup> enhances electronic conductivity and Na<sup>+</sup> ions transport kinetics, while NVPF maintains a higher redox potential associated with the V<sup>3+</sup>/V<sup>4+</sup> couple. This review critically compares NVPF‐ and NVOPF‐based cathodes in terms of crystal structure, sodium storage mechanism, synthesis and modification strategies, and high‐voltage cathode/electrolyte interfacial stability.

Theoretical and experimental studies demonstrate that the F-doping modulates the electronic structure, effectively tuning Fe sites toward a high-spin configuration that optimizes binding energies and induces a chlorophobic effect that repel corrosive (Cl<sup>−</sup>) ions.
