Summary: Silicon is a promising material for next-generation lithium-ion battery anodes due to its high theoretical capacity and low cost. However, its poor cyclability and rate performance limit its large-scale applications. In this study, hollow silicon/germanium nanospheres combined with porous carbon are synthesized and used as lithium-ion battery anodes. The experimental results show that these anodes have small volume expansion, high ion/electron conductivity, and stable electrode interface, while theoretical calculations suggest that using germanium instead of silicon can improve lithium storage ability. These unique characteristics enable the anodes to exhibit high initial specific capacity, superior rate capability, excellent cycling stability, and outstanding stability even at high loading. Moreover, when paired with LiFePO4 cathode, the full-cell shows impressive capacity performance.

Summary: Ag/Ti3AlC2 and Ag/Ti3SiC2 composites are promising for electrical contact applications, but their arc erosion resistance can be further improved by understanding the influence of MAX phases' structural stability on their properties. This study investigates the preparation, physical properties, interfacial reactions, and arc erosion resistances of these composites. Results show that the interfacial reaction between Ag and Ti3AlC2 significantly impacts their properties, while the weaker interfacial reaction in Ag/Ti3SiC2 leads to lower resistivity and hardness but superior arc erosion resistance.

Summary: Ti3AlC2 ceramic shows potential in Ag-based composite electrical contact materials, with wetting behavior improving at higher temperatures. The wetting mechanism of Ag/Ti3AlC2 is proposed based on interfacial structure and chemical composition, with Al-Ag interdiffusion enhancing interface bonding and mechanical properties. On the other hand, absence of Al layer in Ti3C2 results in poor wetting and decreased anti-arc erosion properties with Ag.
