“…In situ polymerization of crosslinkable monomers can be an effective method to fabricate the crosslinked polymer binders for Si‐based anodes 149‐152 . Liu et al introduced a highly stretchable crosslinked polyacrylamide (PAM) hydrogel binder for Si anodes by in situ free radical polymerization of acrylamide monomer and bifunctional N,N‐methylenebisacrylamide (MBAA) monomer (Figure 15A).…”

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.

“…On the other hand, the initial discharge capacity, charge capacity, and ICE of the CNC–SnO 2 NF800 composite electrode were 1752 mA h g −1 , 891 mA h g −1 , and 50.84%, respectively ( Figure 4 b). The first discharge capacities of both of the electrodes were higher than the theoretical capacities of SnO 2 and CNC for the following reasons: (1) the formation of solid–electrolyte interface (SEI) layers on the surface and the decomposition of electrolyte during the first discharge process, leading to an increase in the irreversible capacity of the electrodes; (2) the carbon content of nanocellulose after pyrolysis in nanocomposites; (3) tiny vacancies existing between the SnO 2 and nanocellulose that can buffer the SnO 2 volume expansion, which could be seen in the SEM and HRTEM results; and (4) the constitution of a space charge layer comprised of lithium ions at the interface between the lithium salt and metal particles [ 7 , 28 , 33 , 34 ]. The initial Coulombic efficiencies of the nanocomposites were 52.21% and 50.84% for CNC–SnO 2 NF500 and CNC–SnO 2 NF800 composites, respectively, which were very close to the theoretical values.…”

One of the biggest challenges in the commercialization of tin dioxide (SnO2)-based lithium-ion battery (LIB) electrodes is the volume expansion of SnO2 during the charge–discharge process. Additionally, the aggregation of SnO2 also deteriorates the performance of anode materials. In this study, we prepared SnO2 nanoflowers (NFs) using nanocrystalline cellulose (CNC) to improve the surface area, prevent the particle aggregation, and alleviate the change in volume of LIB anodes. Moreover, CNC served not only as the template for the synthesis of the SnO2 NFs but also as a conductive material, after annealing the SnO2 NFs at 800 °C to improve their electrochemical performance. The obtained CNC–SnO2NF composite was used as an active LIB electrode material and exhibited good cycling performance and a high initial reversible capacity of 891 mA h g−1, at a current density of 100 mA g−1. The composite anode could retain 30% of its initial capacity after 500 charge–discharge cycles.

An efficient and effective process for the production of high-performance anion exchange membranes (AEMs) is necessary for the commercial application of fuel cells. Therefore, in this study, quaternized poly vinylbenzyl chloride (QVBC) and polysulfone were composited with glycidyltrimethylammonium-chloride-quaternized chitosan (QCS) at different ratios (viz., 1 wt %, 5 wt %, and 10 wt %). The structure and morphology of the membranes were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy, respectively. Further, the water uptake, swelling ratio, and ionic conductivities of the composite membrane at different wt % of QCS were evaluated. The membrane with 5% QCS exhibited an ionic conductivity of 49.6 mS/cm and 130 mS/cm at 25 °C and 70 °C, respectively.
