However, lead toxicity and the complicated synthesis process posed major obstacles to their further practical applications. To address these issues, a facile and robust mechanochemical synthesis of cesium manganese halide (Cs3MnX5, X = halide element) was developed via a highly efficient solvent-free ball milling strategy. This green approach exempted the utilization of any harmful organic solvents, thereby enabling the fast and cost-effective production of lead-free Cs3MnX5 with excellent optical properties. Cs3MnX5 perovskites with mixed halide compositions could also be readily fabricated through this eco-friendly approach at room temperature without any post-purification. Furthermore, the robustness of the ball milling strategy was proved by fabricating zinc-doped Cs3MnX5 perovskites with enhanced thermal stability and ambient stability. These features demonstrated that ball milling was highly efficacious for producing high-quality non-toxic halide perovskites, which could be used in light-emitting diodes.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 6","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, despite their remarkable advancements and widespread commercialization, LIBs continue to face critical challenges, particularly the demand for even higher energy density, which inhibits their performance in high-power applications such as electric and hybrid electric vehicles. This review presents a comprehensive analysis of the fundamental limitations hindering LIBs from achieving superior energy density and long-term electrochemical stability. The discussion is systematically structured around four key components: cathode materials, anode materials, separators, and current collectors, with a particular emphasis on the challenges, emerging strategies, and future perspectives. By delving into recent breakthroughs in novel material architecture, electrode design optimizations, and the selection of advanced separators and current collectors, this work provides an in-depth examination of innovative approaches aimed at enhancing battery performance. Furthermore, this review explores pivotal factors such as interfacial stability, ion transport kinetics, and degradation mechanisms that significantly impact the longevity, safety, and efficiency of LIBs.

Experimental results show that the addition of Cu significantly improved the catalyst performance, increasing the conversion rate of methacrolein from 17.2% to 84.2%, while the yield of methacrylic acid was boosted from 5.5% to 51.7%. A series of characterization results showed that both P-Mo-V and Cu-P-Mo-V catalysts primarily exhibited the crystal phase of [PMo12O40]3−, with a small amount of [PMo11VO40]3− phase.

Recently, metal complex or reactive metal inks are attracting research interest due to their significantly low cost and higher performance compared to traditional nanoparticle silver pastes. In this work, we demonstrate, for the first time, screen-printed high-efficiency silicon heterojunction solar cells metallized by silver metal complex inks on industrial G1-size (158.75 × 158.75 mm2) wafers. We demonstrate screen-printed Ag metal complex ink grid patterns with continuous fingers ~100–120 μm wide. The printed Ag grid is very thin (~1 μm), which is an order of magnitude thinner than the current ~20–30 μm fingers printed with low-temperature nanoparticle-based pastes. Double printing allows silicon heterojunction devices with efficiencies >20%. This is the highest efficiency so far, to our knowledge, of industrial solar cell precursors using this metallization technology. Simulation results suggested that increasing the thickness of the metal film does not significantly improve efficiency due to the dense, highly conductive films. So, a single print of ~1 μm finger would be enough to produce cells that perform similarly to a ~20 μm thick nanoparticle paste printed cells. Additionally, solar cells printed on G1 wafers with silver metal complex ink required more than 10 times less silver (~0.03 g) compared to those using silver/copper nanoparticle paste (~0.4 g of Ag). These results indicate that metal complex inks are a very promising replacement for silver nanoparticle pastes for industrial-scale metallization in an age of resource scarcity and high costs of noble metals.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 6","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This performance stems from SiO2 unique lithiation mechanism, which involves its conversion to electroactive silicon (Si) and electrochemically inactive species. However, widespread adoption of SiO2 anodes is hindered by their slow initial lithiation. To address this, research has focused on developing electrochemical “activation protocols” that involve prolonged low-potential holding steps to promote SiO2 conversion. Despite these efforts, the complex and multi-pathway nature of SiO2 lithiation process remains poorly understood, impeding the rational design of effective activation strategies. By introducing a multi-probe characterization approach, this study reveals that, contrary to the previously proposed reaction mechanism of SiO2 anodes, the lithiation process initiates at low potentials with the direct formation of Li4SiO4 and LixSi. Electrochemical activation potential was found to significantly influence the degree of conversion, with 10 mV identified as the optimal cut-off potential for maximizing SiO2 utilization.

Herein, we achieved the green valorization of waste liquid from the natural clay-derived zeolite synthesis process and utilized it to fabricate metal-loaded aluminosilicate dressings with pronounced wrinkled structures (wrinkled Cu–AS, Ga–AS, and Ce–AS) through simple procedures. Wrinkled Cu–AS and Ce–AS exhibited strong antibacterial activity against Escherichia coli, Staphylococcus aureus, and Candida albicans, with wrinkled Ce–AS demonstrating notable antibiotic-like effects against C. albicans. Moreover, wrinkled Ce–AS enhanced hemostatic capability, promoted blood cell aggregation and activation, downregulated inflammatory markers (IL-6/TNFα), stimulated angiogenesis (VEGF), and shifted macrophage polarization toward the M2 phenotype, thereby facilitating rapid wound healing. Sprague–Dawley rats tolerated intraperitoneal administration well, with no observable toxicity as well as satisfactory hemolysis and cell compatibility. Notably, in the context of growing demand for natural clay utilization and zeolite production, this work presents a unique green approach for the efficient reuse of zeolite synthesis waste liquid, offering both environmental sustainability and commercial viability.
