Membrane Technology for Energy Saving: Principles, Techniques, Applications, Challenges, and Prospects

节能膜技术：原理、技术、应用、挑战与前景

Li dendrites penetration through solid electrolytes (SEs) challenges the development of solid‐state Li batteries (SSLBs). To date, significant efforts are devoted to understand the mechanistic dynamics of Li dendrites nucleation, growth, and propagation in SEs, and various strategies that aim to alleviate and even inhibit Li dendrite formation have been proposed. Nevertheless, most of these conventional strategies require either additional material processing steps or new materials/layers that eventually increase battery cost and complexity. In contrast, using external fields, such as mechanical force, temperature physical field, electric field, pulse current, and even magnetic field to regulate Li dendrites penetration through SEs, seems to be one of the most cost‐effective strategies. This review focuses on the current research progress of utilizing external physical fields in regulating Li dendrites growth in SSLBs. For this purpose, the mechanical properties of Li and SEs, as well as the experimental results that visually track Li penetration dynamics, are reviewed. Finally, the review ends with remaining open questions in future studies of Li dendrites growth and penetration in SEs. It is hoped this review can shed some light on understanding the complex Li dendrite issues in SSLBs and potentially guide their rational design for further development.

Progress and Perspective of Controlling Li Dendrites Growth in All‐Solid‐State Li Metal Batteries via External Physical Fields

通过外部物理场控制全固态锂金属电池中锂枝晶生长的进展与展望

This work explores the development of a triboelectric nanogenerator (TENG) based on polyacrylonitrile (PAN) and molybdenum disulfide (MoS 2 ) nanosheets composite fibers for enhancing tribo‐positive electricity to power backscatter communication systems, contributing to the sustainable internet of things (IoT) nodes in future 6 G networks. By incorporating different concentrations of MoS 2 (1, 2, 3, and 4 wt%) nanosheets into PAN nanofibers via electrospinning, the nanocomposite fiber‐based TENGs exhibit improved triboelectric properties. The TENG based on PAN/4% MoS 2 nanocomposite fiber mat achieve a peak open‐circuit voltage of 296 V and a short‐circuit current of 6.16 μA, which represents an ≈95% and 77% enhancement, respectively, in comparison with the TENGs based on neat PAN nanofiber mat. The enhanced charge transfer ability at the PAN and MoS 2 nanosheet interface, the increased dielectric properties, the rougher surface morphology of the composite nanofibers contribute to the enhancements in triboelectric performance. These TENGs are integrated with the backscatter communication system to power a wireless identification and sensing platform (WISP) tag, demonstrating extended transmission range and improved real‐time data acquisition. These findings suggest that TENGs can play a significant role in sustainable energy solutions for 6 G‐enabled IoT applications.

The recycling of lithium‐ion batteries (LIBs) through extractive pyrometallurgy is widely used, but a significant drawback is the loss of lithium to the slag. To address this, lithium‐bearing slag from an industrial LIB recycling plant is analyzed using wavelength dispersive X‐ray fluorescence, inductively coupled plasma optical emission spectroscopy, X‐ray diffraction (XRD), and thermogravimetry coupled infrared. The slag's chemical composition is complex, best described by the ternary system CaO–SiO 2 –Al 2 O 3 , with additional major components being Na 2 O, Fe 2 O 3 , MgO, V 2 O 5 , Mn 2 O 3 , and Cr 2 O 3 . The slag cone shows little chemical zonation and a relatively constant lithium content of Ø 0.82 mass%. The recycling slag shows a mineralogical composition typical of nonferrous slags (e.g., melilite, clinopyroxene, nepheline). Lithium is either bound in β‐eucryptite or, to a lesser extent, in lithium metasilicate. β‐eucryptite contains up to 5.51 mass% lithium stoichiometrically, which is more than typical lithium ores contain. Moreover, β‐eucryptite has potential for the engineering of artificial minerals strategy as an easily implementable lithium phase. β‐eucryptite forms in slags with lower overall lithium content, allowing for the use of slag modifiers that reduce the process temperature. Hence, β‐eucryptite could prove as efficient and feasible option for improving lithium recovery from smelting processes.

Lithium‐Phase Identification in an Industrial Lithium‐Ion‐Battery Recycling Slag: Implications for the Recovery of Lithium

工业锂离子电池回收炉渣中的锂相鉴定：锂回收的意义

Spinel oxides are promising multifunctional electrocatalysts based on earth‐abundant elements. While NiFe 2 O 4 and CoFe 2 O 4 have been widely studied for the oxygen evolution reaction (OER), CuFe 2 O 4 has been less investigated. Herein, cubic CuFe 2 O 4 nanoparticles are synthetic using a microwave‐assisted approach. The effect of post‐synthetic calcination on particle morphology, crystal structure, and inherent properties such as optical bandgap, magnetic moment, or degree of inversion is investigated. The influence of the post‐synthetic treatment on the electrochemical performance is then evaluated. It is found that higher calcination temperatures are beneficial for the OER, the hydrogen evolution reaction, and the oxygen reduction reaction (ORR), which can be explained by an improved crystallinity, removal of organic surface residues and changes in the dominant crystal phase—and relatedly the conductivity. Especially for the ORR activity, an increase in the electrochemical active surface area and a decrease in the charge transfer resistance upon calcination are important prerequisites. The activity of CuFe 2 O 4 for the reduction of CO 2 to CO, in contrast, is mainly determined by the local environment of Cu 2+ and is best at a comparatively high degree of inversion and low amounts of organic residues and for particles with a cubic structure.

Correlations of Calcination Temperature with the Catalytic Properties of CuFe2O4 for the Synthesis of Green Fuels

煅烧温度与CuFe₂O₄催化绿色燃料合成催化性能的相关性

A strategy is proposed to enhance the stability and reusability of the ReO x ‐Pd/CeO 2 catalyst for the consecutive deoxydehydration and hydrogenation (DODH + HG) of biomass‐derived vicinal diols. A remarkable result involving a simultaneous enhancement of activity, stability, and regeneration ability of the catalyst is obtained by lowering the surface concentration of metals. Using erythritol as a model compound, DODH + HG over a low‐loading ReO x ‐Pd/CeO 2 can be completed much faster with a higher turnover number compared to the high‐loading standard catalyst. Moreover, a three‐fold decrease in deactivation rate is also obtained when shifting from a 2 wt% Re‐containing catalyst to a 0.5 wt% one, confirming the enhancement of stability. The regeneration of a low‐loading ReO x ‐Pd/CeO 2 (0.5 wt% Re) can be completely achieved via heat‐treatment under air in milder conditions at a temperature as low as 353 K. Based on Raman spectroscopy, no sign of polymeric ReO x could be detected on the surface of a spent ReO x ‐Pd/CeO 2 (0.5 wt% Re) after a simple oven drying under air, confirming the complete redispersion of the inactive species, which was previously traced as the main cause of catalyst deactivation in the catalyst with a higher metal loading.

The mass deployment of solar energy technology has been inspired by sustainable energy objectives. However, end‐of‐life solar photovoltaic modules present the growing dilemma of solar waste management. A circular economy approach should therefore be applied to the solar industry due to the valuable materials contained within modules, and their upfront emissions and energy intensity. Solar module recycling has to date been delineated into three phases: disassembly, delamination, and extraction. Disassembly has been commercially established; delamination has experienced some progression with further development required to liberate the valuable solar cell material, while extraction has had more limited exploration, predominantly through a hydrometallurgical lens. Extraction via electrochemical methods, however, has received some recent attention in the literature with promising outcomes for both metal extraction and process electrification. Electrochemical approaches offer new methods for more advanced processing options. For example, high‐temperature molten salt electrorefining has been investigated for metallurgical‐grade silicon and could prove to be an effective process for recovering silicon. This review provides an overview of solar module recovery methods, with focus on novel and emerging electrochemical approaches including the applicability of electrorefining to upgrade recovered silicon from photovoltaic waste.

A Review of End‐of‐Life Silicon Solar Photovoltaic Modules and the Potential for Electrochemical Recycling

硅基太阳能光伏组件寿命末期综述及电化学回收潜力

Molybdenene, a full‐fledged metallene has been sensational among all Xenes. Apart from metallicity with excellent carrier concentration, it is anticorrosive, rendering it a superioor electrode material for electrochemical energy storage. As evident from atomic force microscopy, microwave‐synthesized molybdenene constitutes of monolayers (each layer ≈0.4 nm) and lateral dimensions extended to millimeters. Cris‐cross intertwinned crystals with close to square (0.20, 0.21 nm) lattice with fourfold symmetry were observed in electron imaging. Characteristic metallic signal (Mo–Mo vibration) in Raman peak at ≈405 cm −1 proves chemical phase purity. The electrochemical performance of synthesized molybdenene sheets is evaluated for supercapacitor applications in a 2 m KOH electrolyte. The as‐synthesized molybdenene demonstrates a specific capacitance of 327.78 F g −1 at a scan rate of 10 mV s −1 and 118.6 F g −1 at a current rate of 0.50 A g −1 in a three‐electrode configuration, with a capacitance retention of 81.0% over 5000 cycles. Furthermore, an asymmetric supercapacitor employing molybdenene as the positive electrode and activated carbon as the negative electrode exhibits an energy density of 15.94 Wh kg −1 at a power density of 399.72 W kg −1 . These findings highlight molybdenene as a promising candidate for high‐performance electrochemical energy storage devices.
