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.

“…In addition, the use of an interface modification layer can protect the electrolyte so that the high‐voltage anode material is coated with a ceramic solid electrolyte. These approaches not only increase the electrochemical window of the composite electrolyte but also make it possible to combine it with high‐voltage anodes [104] . According to the performance of different interfaces, different electrolytes with optimization ability are selected based on the basis, and they are combined together to prepare composite electrolytes with different structures to meet the performance requirements of different interfaces.…”
Solid electrolyte lithium batteries are the next generation of advanced energy devices. The incorporation of solid electrolytes can significantly improve the safety issue of lithium‐ion batteries. Organic‐inorganic composite solid electrolytes (CSE) are promising candidates for solid‐state batteries, but their application is mainly limited by low ionic conductivity. Many studies have shown that the architecture of ordered inorganic fillers in CSE can act as fast lithium‐ion transfer channels by auxiliary means, thus significantly improving the ionic conductivities. This review summarises the recent advances in CSE with different dimensional inorganic fillers. Various effective strategies for the construction of ordered structures in CSE are then presented. The review concludes with an outlook on the future development of CSE. This review aims to provide researchers with an in‐depth understanding of how to achieve ordered architectures in CSE for advanced solid state lithium batteries.
“…Traditional LIBs use highly flammable ester solvents as their electrolytes. [1][2][3][4][5][6][7] However, when LIBs provide power for some electrical vehicles like electrical cars, which need fast and effective charging, they could cause safety hazards. At high voltage charge, the organic electrolyte in LIBs could react with the electrode and catch fire and even explode.…”
