While silicon is considered one of the most promising anode materials for the next generation of high‐energy lithium‐ion batteries (LIBs), the industrialization of Si anodes is hampered by the anode's large volume change during the charging and discharging process. In comparison to the traditional graphite anode used in LIBs, the Si anode places more stringent demands on the binder, which must maintain intimate contact between the electrode components and the integrity of the ion and electron transport channels when subjected to frequent large volume changes. The purpose of this review is to cover the recent advances in binder design strategies by examining the molecular structure, chemical functionalities, physical and mechanical properties of the binder materials, as well as the working strategies involved. The challenges in the design of the innovative polymer binder for commercializing Si anodes are discussed, as well as the future development direction and application prospects.

increased frequency of weather extremes and related energy and environmental issues affecting all living species on the planet. As a result, a CO 2 -management scheme has been stimulated and proposed. To begin with, the development and deployment of carbon capture technologies has been widely acknowledged as a strong imperative for decarbonizing industry and promoting net CO 2 removal from the atmosphere. [4,5] Following the carbon capture, the conventional storage process, however, is unprofitable per se that requires large capital investment, heavily hindering its applicability in the commercial sector; meanwhile, more issues remain in the safety of underground and ocean CO 2 storage, while the potential locations are still under survey and assessment. A promising alternative to storage is the purposeful utilization of CO 2 as a renewable feedstock for producing high-value-added chemicals and fuels, which could not only curb carbon emissions but also provide a revenue stream that offsets capture costs and may even create positive cash flow. The conversion of CO 2 to chemicals and energy products using renewable resources such as solar, wind, and tide not only enables the storage of intermittent renewable energy in chemical bonds for easy transportation and efficient utilization, but also fulfills a transition from a liner carbon economy to a circular carbon-neutral economy for energy sustainability (Figure 1). [6,7] Recent years have witnessed the great progress in the realm of sustainable CO 2 -management materials, especially centering on CO 2 capture, utilization, and catalytic conversion, contributing to a promising and potent solution to both emissioncontrol and energy-supply challenges. However, there is a lack of a timely review on the state-of-the-art advances of holistic CO 2 -management technologies from the material perspective. The purpose of this review is to provide a critical and complete overview of the main and emerging development of promising materials for sustainable CO 2 management. We give in-depth analyses of CO 2 capture, catalytic conversion, and direct use at numerous scales of material research, ranging from mechanism comprehension through targeted design and fabrication, property manipulation, to industrial implementation. Meanwhile, strategic considerations for both liquid and solid CO 2 capturing materials under various operational conditions as With the rising level of atmospheric CO 2 worsening climate change, a promising global movement toward carbon neutrality is forming. Sustainable CO 2 management based on carbon capture and utilization (CCU) has garnered considerable interest due to its critical role in resolving emission-control and energy-supply challenges. Here, a comprehensive review is presented that summarizes the state-of-the-art progress in developing promising materials for sustainable CO 2 management in terms of not only capture, catalytic conversion (thermochemistry, electrochemistry, photochemistry, and possible combinations), and direct utilization, but also eme...

Here we report on a selective and sensitive graphene-oxide-based electrochemical sensor for the detection of naproxen. The effects of doping and oxygen content of various graphene oxide (GO)-based nanomaterials on their respective electrochemical behaviors were investigated and rationalized. The synthesized GO and GO-based nanomaterials were characterized using a field-emission scanning electron microscope, while the associated amounts of the dopant heteroatoms and oxygen were quantified using x-ray photoelectron spectroscopy. The electrochemical behaviors of the GO, fluorine-doped graphene oxide (F-GO), boron-doped partially reduced graphene oxide (B-rGO), nitrogen-doped partially reduced graphene oxide (N-rGO), and thermally reduced graphene oxide (TrGO) were studied and compared via cyclic voltammetry (CV) and differential pulse voltammetry (DPV). It was found that GO exhibited the highest signal for the electrochemical detection of naproxen when compared with the other GO-based nanomaterials explored in the present study. This was primarily due to the presence of the additional oxygen content in the GO, which facilitated the catalytic oxidation of naproxen. The GO-based electrochemical sensor exhibited a wide linear range (10 µM–1 mM), a high sensitivity (0.60 µAµM−1cm−2), high selectivity and a strong anti-interference capacity over potential interfering species that may exist in a biological system for the detection of naproxen. In addition, the proposed GO-based electrochemical sensor was tested using actual pharmaceutical naproxen tablets without pretreatments, further demonstrating excellent sensitivity and selectivity. Moreover, this study provided insights into the participatory catalytic roles of the oxygen functional groups of the GO-based nanomaterials toward the electrochemical oxidation and sensing of naproxen.

theoretical energy density, low reduction potential of metallic Li, and their inherent safety provided by the solid-state electrolyte (SSE), [1][2][3] As the core component, the development of SSE with superior lithium-ion conductivity and stability plays a critical role in the realization of such batteries. [4][5][6] Compared to oxide or sulfidebased inorganic SSEs which are brittle and difficult to process, organic SSEs, such as poly(ethylene oxide), received wide attention due to their advantages including lightweight, flexible, scalable, and good interfacial compatibility with electrodes. [7,8] However, poor mechanical strength, insufficient thermal stability, and low ionic conductivity at room temperature (RT) of 10 −6 to 10 −5 S cm −1 reduce their commercial viability. [9,10] Despite various strategies including chemical crosslinking, [11] block copolymerization, [12] grafting, [13][14][15] filling with liquid plasticizers, [16][17][18] or combining with inert fillers, [19][20][21][22][23][24][25] to solve the aforementioned drawbacks for polymeric SSEs, the performance compromise between ion conductivity, transference number, mechanical strength, and satisfied lifespan has persisted for decades. [7] More efforts such as the development of novel materials and/or improved architectures, and even dramatical transformation of conventional polymeric SSEs and corresponding Li + -transport mechanism, are necessary and urgent to satisfy future energy storage needs. [4] The polymetric electrolytes with small amounts of liquid electrolyte to form a quasi-solid-state electrolyte (QSSE) might be an available strategy to improve the safety and electrochemical performance simultaneously.A common idea gaining popularity in scientific and technical societies is to learn from nature and thereby gain inspiration for material design. [26] Such an example can be found in trees, which possess an efficient internal nutrition delivery system and a robust mechanical structure that allows them to adapt to their natural environment. For instance, a tree trunk is mostly composed of inside xylem, middle cambium, and outside bark (Figure 1a and Figure S1, Supporting Information). [27] The inner xylem (sapwood and heartwood) acts as the framework to provide structural support with robust mechanical strength. [27][28][29] The bark (living phloem and outmost bark) that outer covers the tree's trunk and branches can transport nutriment formed throughThe construction of robust (quasi)-solid-state electrolyte (SSE) for flexible lithium-metal batteries is desirable but extremely challenging. Herein, a novel, flexible, and robust quasi-solid-state electrolyte (QSSE) with a "tree-trunk" design is reported for ultralong-life lithium-metal batteries (LMBs). An in-situgrown metal-organic framework (MOF) layer covers the cellulose-based framework to form hierarchical ion-channels, enabling rapid ionic transfer kinetics and excellent durability. A conductivity of 1.36 × 10 −3 S cm −1 , a transference number of 0.72, an electrochemical window of 5.2...
