Nonetheless, the problems of lifespan and reversibility caused by dendrites, hydrogen evolution and corrosion reactions restrict the large-scale commercialization of AZIBs. Herein, a multifunctional strategy has been explored in this research, of which the porous submicron-CaF2 layer with uniform channels is applied to the zinc anode by employing a straightforward, low-cost method. Moreover, the submicron-CaF2 coating can provide abundant submicron channels, restricting the free diffusion of Zn2+ and effectively preventing the growth of zinc dendrites. Additionally, a series of characterizations reveal that the Zn@CaF2 anode has a high cycle reversibility due to the marked suppression of the corrosion and hydrogen evolution reactions provided for the desolvation effects of CaF2. Consequently, the Zn@CaF2 symmetrical cell afforded a long cycling lifespan for more than 1850 h at 1 mA cm-2. Importantly, even at a high current of 8 mA cm-2, the symmetrical cell can stably maintain for 2000 cycles. As a proof of the strategy, the entire Zn@CaF2//Zn3V2O8∙1.85H2O cell outperformed the full cell with bare Zn anode through superior capacity retention.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"53 11 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139589528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The theoretical and experimental results indicate that BPO molecules with zwitterionic resonance structure can accept electrons and change the charge state of perovskite surface to modify the energy-level. In addition, the multi-group passivation of BPO molecules which contain “bipyridyl nitrogen” and bicarbonyl groups, can chelate the Pb defects such as Pb-I antisite (PbI) and iodine vacancy (VI).

However, the practical application of Lithium metal anodes (LMAs) faces several significant challenges due to their unwanted reactions with the electrolyte to continuously form Li dendrites. These issues significantly hinder both electrochemical performance and safety. To overcome these challenges, fluorinated organic materials (FOMs), with their unique chemical and physical properties, offer an exciting avenue for enhancing cycle stability and energy density of batteries. This is attributed to their higher electrolytic window and chemical stability. This review would provide a comprehensive overview of the crucial role played by FOMs in safeguarding LMAs, such as F-containing electrolyte engineering, separator modification, and artificial SEI. Additionally, it intends to explore the challenges and latest advances in this domain, with the ultimate objective of offering insights and forward-looking perspectives for future research initiatives in related areas.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"14 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139554809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we introduce a flexible carbon/ferroelectric/thermoelectric (i.e., C/FE/TE) hybrid film with layer-by-layered carbon, PZT/PVDF-TrFE, and bismuth telluride alloys (p-type Bi0.5Sb1.5Te3 or n-type Bi2Te2.5Se0.5), it enables us to achieve thermoelectric cooling and electromagnetic shielding concurrently. More importantly, the electrical performance of the thermoelectric layer can be tuned by the polarization of the ferroelectric layer, and the maximum power factors of 12.7 μW cm-1 K-2 and 5.3 μW cm-1 K-2 are obtained for Bi0.5Sb1.5Te3 and Bi2Te2.5Se0.5, respectively. Using these C/FE/TE hybrid films, we fabricated a radial-shaped flexible thermoelectric cooling device, which showed a net cooling temperature difference of 1.08 K at 300 K. In addition, the impedance mismatch between free space and C/FE/TE induces reflection loss, the bismuth telluride alloys and carbon layers cause conduction loss, while the polarized PZT/PVDF-TrFE, as well as the interfacial polarization between bismuth telluride alloys and PZT/PVDF-TrFE layers leads to polarization loss. Thus, a high electromagnetic shielding performance with a maximum average shielding efficiency of 32.0 dB in the frequency range of 8.2 ∼ 12.4 GHz (i.e., X-band) was also achieved in the C/FE/TE hybrid film.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"5 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139554581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If the cost of producing hydrogen falls far below that of fossil fuels, it will be able to run the transportation, construction, and energy sectors. The vision of a decarbonized future in which hydrogen is used as a common fuel will be realized soon through infrastructural developments. Aluminium (Al) and water react to produce hydrogen on-site, which is a simple and affordable process. Two benefits come from this: first, it eliminates the need for additional logistics for the storage and shipping of hydrogen; second, water is easily accessible in the field and Al is safer to use. Although this technique appears intriguing, a major barrier to its wide-spread applications is the development of a passive oxide layer on the Al surface. The advantages and disadvantages of various Al activation techniques are covered in this review article. In addition to analyzing the effectiveness and technical issues of the Al-water reaction techniques used to power on-site hydrogen-powered fuel cell vehicles, it gives a critical examination of key parameters that derive the Al-water reaction mechanism.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"255 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139554769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the strict low humidity control increases the costs for manufacturing facilities and hinders the large-scale production of PSCs. In this work, a sequential deposition method was used to prepare the perovskite intermediate phase, and the impact of ambient humidity was studied during the annealing process. It is shown that proper humidity has a positive effect on the perovskite layer, which is conducive to accelerate the reaction between organic salts and PbI2 and improve the surface morphology of the film. The perovskite annealing under 55% relative humidity exhibits fewer defects and faster carrier transport kinetics. The resulting PSCs, with all layers fabricated adopting vapor deposition, yield a power conversion efficiency (PCE) of 15.01% for the large area modules of 100 cm2 (active area 64.8 cm2). More impressively, the PCE of the unpackaged cell modules remained above 80% after being placed in ambient air for 1200 h.
