“… 130 Except for the crosslinking reaction between macromolecules, small molecules containing two or more –COOH or –OH groups can be applied as crosslinkers to fabricate the interconnected networks for Si‐based anodes (Figure 11D). For example, D‐sorbitol crosslinked PAA, 136 fumaric acid crosslinked PVA 102 and citric acid crosslinked CMC 137 have been reported to show enhanced mechanical strength and greatly improved cycling performances of Si‐based anodes, compared to that of linear PAA, PVA or CMC binders.…”

“…Oh et al first studied the high M w PVA as a potential binder for Si/Gr anodes. 99 In fact, the employing of PVA as binder for Si-based anodes often involves a branching, 85,100 crosslinking 93,94,[101][102][103] and modification 104,105 designing, which will be discussed in the following sections. The -COOH and -OH groups are the most important functional groups in many polymer binders for Si-based anodes.…”

Conventional lithium‐ion batteries (LIBs) with graphite anodes are approaching their theoretical limitations in energy density. Replacing the conventional graphite anodes with high‐capacity Si‐based anodes represents one of the most promising strategies to greatly boost the energy density of LIBs. However, the inherent huge volume expansion of Si‐based materials after lithiation and the resulting series of intractable problems, such as unstable solid electrolyte interphase layer, cracking of electrode, and especially the rapid capacity degradation of cells, severely restrict the practical application of Si‐based anodes. Over the past decade, numerous reports have demonstrated that polymer binders play a critical role in alleviating the volume expansion and maintaining the integrity and stable cycling of Si‐based anodes. In this review, the state‐of‐the‐art designing of polymer binders for Si‐based anodes have been systematically summarized based on their structures, including the linear, branched, crosslinked, and conjugated conductive polymer binders. Especially, the comprehensive designing of multifunctional polymer binders, by a combination of multiple structures, interactions, crosslinking chemistries, ionic or electronic conductivities, soft and hard segments, and so forth, would be promising to promote the practical application of Si‐based anodes. Finally, a perspective on the rational design of practical polymer binders for the large‐scale application of Si‐based anodes is presented.

“…1,2 Fumaric acid has traditionally been used in the production of food acidity regulators, 1 feed preservatives, 3−5 and other high-potency chemical products. 6−8 Recently, fumaric acid has been applied in metal–organic frameworks, 9,10 polymer composites, 11,12 composite anodes of high-energy lithium batteries, 13 co-crystals, 14,15 and microenvironment tablets. 16 Thus, the demand for fumaric acid has dramatically increased with the expansion of the application scope for fumaric acid, which has made it necessary to study effective fumaric acid production methods.…”

In recent years, the increase in demand for fumaric acid from industry has resulted in an increased need for a high-selectivity process for the conversion of maleic acid to fumaric acid. A highly selective conversion of fumaric acid was achieved without a catalyst by a simple one-step hydrothermal reaction. In addition, the competitive conversion of maleic acid, fumaric acid, and malic acid was first systematically investigated in detail without using a catalyst. The products were characterized by X-ray diffraction and Fourier transform infrared, which demonstrated that the product was fumaric acid. The highly selective conversion of fumaric acid was achieved, and the yield of fumaric acid could reach 92%. Furthermore, a reaction kinetic model was put forward to study the competitive transformation process. The kinetic model predictions were found to agree well with the experimental data. The kinetic parameters were used to explain the changes in the content of every substance at different reaction temperatures and reaction times. In addition, the initial maleic acid concentration in the reaction was also considered as an influencing factor. These results can facilitate the conditional control and product control of industrial processes for the production of fumaric acid or malic acid using latter without a catalyst.
