Because tritium breeding is intrinsically inefficient, some blanket concepts call for very high lithium-6 enrichments. We assess whether such levels are justified by examining cost, breeder blanket design, and proliferation risk. Taken together, these considerations support keeping most commercial fusion applications below the 60% intermediate-grade boundary proposed in this paper. Distinct enrichment thresholds would strengthen safeguards, material accountancy, and supply-chain monitoring. From a non-proliferation perspective, this would preserve a clearer boundary between civil and more sensitive material, making suspicious enrichment activity easier to identify. Such limits would affect some current tritium-breeding concepts and require reassessment of elements of the current breeding paradigm. More broadly, lithium supply and isotopic enrichment should be treated as governance and regulatory priorities for fusion deployment.</div></div>","PeriodicalId":343,"journal":{"name":"Joule","volume":"10 8","pages":"Article 102596"},"PeriodicalIF":37.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148624261","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}

Here, we systematically investigate this interface using Li<sub>6</sub>PS<sub>5</sub>Cl and six (oxy)halide solid electrolytes across three cell configurations. We show that the triple-phase boundary between the active material and two solid electrolytes is intrinsically detrimental, leading to rapid performance decay regardless of the (oxy)halide chemistry. High-capacity retention is only achieved when this boundary is avoided. <em>Ex situ</em> and <em>operando</em> X-ray photoelectron spectroscopy (XPS) reveal the formation of localized degradation products, including metal sulfides and elemental sulfur/oxidized sulfide compounds, alongside sulfur gas evolution at ∼4.3 V vs. Li⁺/Li.

However, the development of these materials, particularly in multi-cation (e.g., formamidinium [FA]/methylammonium [MA]/cesium [Cs]) mixed-halide compositions, is severely hampered by light-induced phase segregation and large open-circuit voltage deficits. This instability originates from compositional heterogeneity established during film crystallization, leading to localized band-gap variations and detrimental carrier recombination pathways. Here, we report a molecular-complex doping strategy that achieves spatially homogeneous elemental distribution in 1.78 eV FA0.8MA0.1Cs0.1(I0.6Br0.4)3 perovskite films. Consequently, we fabricate a WBG perovskite solar cell that delivers a Voc exceeding 1.38 V (surpassing 90% of its thermodynamic limit) and a power conversion efficiency of over 20.5%, with a fill factor above 83%. Integrating this optimized subcell with a narrow-band-gap perovskite, we demonstrate a monolithic all-perovskite tandem solar cell achieving a power conversion efficiency of 30.4% (certified at 29.7%).","PeriodicalId":343,"journal":{"name":"Joule","volume":"5 1","pages":""},"PeriodicalIF":39.8,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728041","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}
