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 the year 2019, it is believed that the SiOx-based anode has been commercialized in cylindrical cells which are used in electric vehicles.

We have some other commercially available SiO-C anode samples, which have a lower capacity (420mAh/g ~650mAh/g) but better cycling performance. Please contact for detail.
