High-performance SiO/C as anode materials for lithium-ion batteries using commercial SiO and glucose as raw materials

Zi-Long Wu et al.

Summary: Silicon monoxide (SiO) is considered to be a promising anode material for lithium-ion batteries with higher capacity and longer cycle life. In this study, glucose was used as a carbon source to synthesize SiO/C composite with high performance. Optimal conditions for SiO/C synthesis were found to be the addition of 5 wt% glucose and a calcination temperature of 800 degrees C. The resulting SiO/C material showed excellent electrochemical performance and stability, making it suitable for LIB applications.

Orientated VSe2 nanoparticles anchored on N-doped hollow carbon sphere for high-stable aqueous energy application

Jing Xu et al.

Summary: In this work, VSe2 nanoparticles are vertically anchored on N-doping carbon hollow nanosphere to create the VSe2@NC electrode, which exhibits outstanding electrochemical properties. An asymmetric supercapacitor assembled using this electrode shows high energy density and stable cycling performance. The superior properties are attributed to the particular hollow structure design accommodating the high specific capacity of VSe2 and desired electrical conductivity of N-doping carbon sphere template.

Preparation and electrochemical properties of novel silicon-carbon composite anode materials with a core-shell structure

Heng-chao Jin et al.

Summary: The multi-component porous Si-SiOx (pSi) and carbon nanofibers hybrids (pSi-CNFs) were successfully prepared by pretreatment of SiO and catalytic chemical vapor deposition. The core-shell structure formed by uniformly coating CNFs on the surface of pSi improved the conductivity of the composites and enhanced the cycling stability and capacity retention of the pSi-CNFs.
