However, existing water-induced electric generator devices predominantly rely on inorganic materials with limited research on naturally available, bio-based materials for hydrovoltaic energy harvesting. This study introduces a novel nutshell-based hydrovoltaic water-induced electric generator for the first time. This low-cost, organic, and efficient renewable energy source can generate a voltage above 600 mV with a power density exceeding 5.96 μW cm−2 utilizing streaming and evaporation potential methodologies, which can be sustained for more than a week. Notably, after further chemical treatments and combining the physical and chemical phenomena, output voltage and maximum current density reach a record high of 1.21 V and 347.2 μA cm−2 respectively, which outperforms most inorganic and organic materials-based water-induced electric generators. By connecting two units in series and parallel, this eco-friendly water-induced electric generator can power an LCD calculator without the assistance of any rectifier. We believe that this novel nutshell-based water-induced electric generator provides a significant advancement in water-induced electric generator technology by offering a sustainable solution for powering electronic devices utilizing agricultural waste.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 5","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144774024","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}

Despite these advantages, the development of Li-Se batteries is impeded by several intrinsic challenges, including volume expansion during the discharge process and the consequent sluggish reaction kinetics that undermine their electrochemical performance. In this study, MIL-91(Al) is used as an electrode additive to accelerate the one-step mutual solid–solid conversion reaction between Se and Li2Se in the carbonate-based electrolyte. By doing so, uncontrollable deposition of Li2Se is effectively mitigated, enhancing the electrochemical performance of the system. Thus, the use of MIL-91(Al) results in reduced internal resistance and faster Li-ion transfer rate, as analyzed by SPEIS and GITT. Ab initio calculations and molecular dynamics simulations further reveal that Li2Se anchors to closely situated dangling oxygens of the phosphonate group of the organic linker of MIL-91(Al), inducing relaxation of the Li-Se-Li angle and stabilizing the overall structure. Accordingly, the MIL-91(Al)-containing Li-Se cells demonstrate a high specific capacity of approximately 530 mAh g−1 at 1C (675 mA g−1) after 100 cycles and retaining a specific capacity of 320 mAh/g even under high current rate (20C) after 200 cycles. This research underlines the importance of the use of electrocatalyst/electroadsorbent materials to enhance the redox kinetics of the conversion reactions between Se and Li2Se, thus paving the way for the development of high-performance Li-Se batteries.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 5","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144774060","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}

Plastic deformation for microstructure engineering has been demonstrated as a viable approach to enhance the elastic strain. However, this approach is highly dependent on the material's plasticity, which is rather limited by the rigidity for the majority of inorganic semiconducting thermoelectric materials. Thermocouple materials, as metallic thermoelectric materials, possess a favorable plasticity, motivating this work to focus on the elastic bendability of a metallic thermoelectric generator that is composed of K-type thermocouple components, namely p-type Ni90Cr10 and n-type Ni95Al2Mn2Si. The cold-rolling process enables a large elastic modulus and a high yield strength, thanks to the texturized direction along <111>, and dense dislocations and refined grains, respectively, eventually resulting in a 400% increase in the elastic strain. Such superior elasticity ensures the preservation of the initial transport properties for the rolled films even after being bent 100 000 times within a radius of ~8 mm. A power output of ~414 μW is achieved in a ten-leg flexible thermoelectric device, suggesting its substantial potential for powering wearable electronics.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 5","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144773971","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, conventional BPs are based on graphite sheets, which provide mechanical properties and corrosion resistance but have limitations in terms of electrical conductivity. Although carbon nanotubes (CNTs) have excellent properties, CNT composites with low CNT volume fractions (10–20%) have increased electrolyte permeability and limited electrical conductivity improvement, resulting in low durability and efficiency for VRFBs. This study proposes a novel concept of horizontally aligned CNT nanocomposite bipolar plate (HACN-BP) to address these issues. The HACN-BPs feature an optimized conduction path with a CNT volume fraction of 59%, resulting in reduced manufacturing time while demonstrating superior conductivity and permeability compared to conventional BPs. Furthermore, integrated HACN-BP mitigates ohmic loss that occurs in the BPs, thereby mitigating the potential drop by 40%. Therefore, the utilization of HACN-BP shows superior performance compared to recent studies, a substantial improvement of more than 6% in energy efficiency and 14% in capacity over conventional BP.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 5","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144773970","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}

Herein, we propose a novel approach by developing halloysite-based X-ray-activated persistent luminescent hydrogels with self-healing properties, which can emit visible luminescence even after switching off the X-ray irradiation. The afterglow properties can be well regulated by controlling the crystal form of the anchored nanocrystal on the surface of the halloysite nanotube, enabling the “time-lock” encryption. Additionally, the absence or presence of photoluminescence behaviors can also be controlled by changing the crosslinkers in synthesizing hydrogels. Six types of hydrogels were reported by means of condensation reactions, which show diverse emission and afterglow properties. By taking advantage of these features, the hydrogels were programmed as a display panel that exhibits three types of fake information under the wrong decoding tools. Only when the right stimuli are applied at the defined time does the panel give a readable pattern, allowing the encrypted information to be recognized.

The lithium-sulfur batteries display extraordinary features, but they suffer from sulfur's non-conductivity, the shuttle effect that results from polysulfide dissolution, volumetric sulfur changes during charging, and dendrites at the anode, resulting in a decline in capacity and a short battery life. As a result of rigorous and innovative engineering designs, lithium-sulfur batteries have been developed to overcome their drawbacks and utilize their entire potential during the past decade. This review will pay particular attention to porous carbon-based matrix materials, especially graphene-based nanocomposites that are most commonly used in producing sulfur cathodes. We provide an in-depth perspective on the structural merits of graphene materials, the detailed mechanism by which they interact with sulfur, and essential strategies for designing high-performance cathodes for lithium-sulfur batteries.
