Amorphous silicon (a -Si) is a widely studied noncrystalline material, and yet the subtle details of its atomistic structure are still unclear. Here, we show that accurate structural models of a -Si can be obtained using a machine-learning-based interatomic potential.
This review highlights the recent advances in using amorphous materials (AMs) for fabricating lithium-ion and post-lithium-ion batteries, focusing on the correlation between material structure and properties (e.g., electrochemical, mechanical, chemical, and thermal ones).
See all authors Amorphous solid-state electrolytes (SSEs) play a pivotal role as fundamental components within all-solid-state lithium batteries, yet their understanding lags behind that of crystalline materials. In this work, a novel amorphous SSE 5Li 2 S-3SiS 2 (mol %) with a high ionic conductivity of 1.2 mS cm −1 is first reported.
Amorphous Si is formed by utilizing the rapid quenching process where Si atoms have no time to diffuse. Amorphous silicon/carbon (a-Si@C) composites were prepared through an environmentally friendly liquid-phase carbon coating strategy using water as solvent to improve their performance.

Aluminum batteries are one of the most sustainable electrochemical storage systems. An amorphization strategy has been reported to obtain high-performance metallic aluminum anode. Based on the operando lithium alloying/dealloying reaction, the artificial amorphous aluminum (a-Al) layer could be obtained (Figure 12c ). [ 29]
