Title:
LITHIUM ION SECONDARY BATTERY ELECTRODE MATERIAL MANUFACTURING DEVICE, LITHIUM ION SECONDARY BATTERY ELECTRODE MATERIAL MANUFACTURING METHOD, AND SPENT POSITIVE ELECTRODE ACTIVE MATERIAL REGENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/065492
Kind Code:
A1
Abstract:
A lithium ion secondary battery electrode material manufacturing device according to the present invention comprises: a layer formation section (1) in which a melted lithium-containing material is sprayed onto an electrode raw material to form a lithium-containing material layer on the electrode raw material; and a heat treatment section (2) in which the electrode raw material having the lithium-containing material layer formed thereon is heated, and the lithium contained in the lithium-containing material is introduced into the electrode raw material to obtain a positive electrode active material.
