Lithiation and Delithiation Properties of Silicide/Si Composite Alloy Electrodes Prepared by Rapid Quenching Method

Rapid quenching is one of the methods for preparing silicide/Si composite alloy as an active material for negative electrode in lithium-ion batteries. In this study, we focused on the method’s control over the positional relation between the Si and silicide phase by changing the additive elements. V...

Description
Summary:Rapid quenching is one of the methods for preparing silicide/Si composite alloy as an active material for negative electrode in lithium-ion batteries. In this study, we focused on the method’s control over the positional relation between the Si and silicide phase by changing the additive elements. Various Si-alloys and the relationship between their lithiation and delithiation properties and their arrangement was investigated.
