Guaranteed Safe Checkout

Si monoxide (SiO) and its suboxides (SiOx) are a group of promising anode materials for lithium-ion batteries that have attracted special attention recently due to their high specific capacity and improved cycling performance compared with nano silicon-based anode. In the material, nanosized (or amorphous) silicon particles are embedded in the oxide matrix, which maintains the structure and also buffers the volume expansion during lithium insertion/removal. In 2019, it is believed that the SiOx-based anode was commercialized in cylindrical cells that are used in electric vehicles.

The sample is a SiO sample coated by carbon with the CVD method. The capacity reaches more than 1550mAh/g.
