Summary: This study focuses on the design and failure analysis of a silicon (Si) anode for lithium-ion batteries (LIBs). The volumetric energy density of the Si anode depends heavily on factors such as Si/C loading, anode calendering density, first-cycle coulombic efficiency, and anode capacity density. Stable Si/C electrode structure is crucial for long-term cycling, and the degree of prelithiation needs to be balanced with cycle life.

Summary: The silicon suboxide (SiO) anode material shows promise for Lithium-ion batteries (LIBs) due to its high theoretical capacity, but it faces challenges such as large volume change (200%), low electrical conductivity, and low first Coulombic efficiency. A ternary composite ((SiOx/G/SnO2)@C) with a carbon coating layer is developed to address these issues, where graphite as part of the active materials improves Coulombic efficiency and controls volume change, and the carbon coating layer is designed to further restrain the high-volume change of SiOx. With the presence of SnO2, the composite exhibits improved electrochemical performance. Experimental results show that (SiOx/G/SnO2)@C achieves a first charging capacity of 382.6 mAh g(-1) at a current density of 100 mA g(-1), with the Coulombic efficiency improved from 62.2% to 74.9%. After 110 cycles, the capacity reaches 424.6 mAh g(-1) and the capacity retention rate is 103.9%.

Summary: Silicon suboxide (SiOx) is a potential anode material for high-energy-density lithium ion batteries, but its electrochemical performance is hindered by mechanical instability due to volume variation. In this study, a sandwich-like structure is proposed, where SiOx nanoparticles are sandwiched between graphene sheets and amorphous carbon layer, improving the structural stability. The resulting C/SiOx@graphene material exhibits excellent cyclic performance and rate capability, offering a novel strategy to enhance the stability of high-capacity anode materials for lithium/sodium ion batteries.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
