Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT High‐capacity SiOx/graphite (SiO/G) anodes offer great potential for advancing lithium‐ion battery technology; however, their practical application is limited by low initial coulombic efficiency (ICE) and rapid capacity decay. These challenges primarily arise from unstable phase transitions and the formation of the solid electrolyte interphase

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation
