“…Recently, the first-principle DFT was applied to investigate the possibility of using a monocyclic aromatic hydrocarbon-derived structure (Figure 6f) as the LIB anode. [130] This 2D structure resembles monoene or graphene; the moiety of the tin atoms are substituted by Si to form a novel SnÀ Si alloy. The calculation results show that the optimized structure can improve the anode performance.…”

Due to the high theoretical lithium storage capacity and moderate voltage platform, silicon is expected to substitute graphite and serves as the most promising anode material for lithium-ion batteries (LIBs). However, substantial volume change during cycling subjects the silicon anode to electrode pulverization and conductive network damage, extensively limiting its commercial purpose. Strategies, such as alloying, nano-crystallization, and compositing, are developed against these problems. This review introduces the attractive alloying modification method and summarizes the recent advances in microstructureengineered silicon alloy anodes for LIBs. The electrochemical performances of silicon alloy anodes with various morphologies, such as nanoparticles, nanowires, two-dimensional layered structures, porous structures, and thin films, are discussed in detail. The challenges for the commercial application of silicon alloy anodes are elaborated in the end. This review provides a comprehensive overview and concerns of microstructure-engineered silicon alloy anodes for potential applications in LIBs.

“…The so-prepared nanostructured thin films are macroporous and are promising candidates for electrochemical applications. [32] Experimental Section Synthesis of PMMA opals: The polymethylmethacrylate (PMMA) opals with desired size were prepared by emulsion polymerization as described by Smarsly et al [30] 35.5 g Methylmethacrylate (MMA) and 5.0 mg sodium dodecyl sulfate (SDS) were added under stirring to water (98.0 mL). The water had been purged with nitrogen under reflux conditions for 0.5 h beforehand.…”

Tin and mixed tin/germanium thin films hold great potential for a variety of different applications such as anodes for lithium ion batteries or optical components in new LED developments. While the physical and chemical properties of these materials are promising, the fabrication of nanostructures with tunable composition and electronic properties is eminently important to overcome several problems in application. In this work we report on the preparation and characterization of inverse opal-structured Sn and Sn/Ge thin films with a pore size of 200 nm on a wide variety of substrates obtained by a simple, upscalable wet-chemical synthetic route involving soluble [Sn 9 ] 4À , [Ge 9 ] 4À and mixed Sn/Ge Zintl clusters. The resulting honeycomb structures are characterized by SEM, EDX, XPS, and Raman spectroscopy. Their porous structure and tuneable composition makes them attractive candidates for electrochemical applications such as anode materials.
