Title:

METHOD FOR PREPARING SILICON ANODE MATERIAL, FOR LITHIUM-ION SECONDARY BATTERY, TO WHICH BORON OXIDE IS APPLIED

Document Type and Number:

WIPO Patent Application WO/2023/210869

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing a silicon anode material, for a lithium-ion secondary battery, to which boron oxide is applied and, more specifically, to a method for preparing a silicon anode material, for a lithium-ion secondary battery, to which boron oxide is applied, which can not only lower the unit price of an anode material by using planar silicon formed from silicon kerf, but also prepare a silicon material having a suppressed initial irreversible capacity by including boron oxide.
