Title:
METHOD FOR REGENERATING LITHIUM COMPOSITE OXIDE, LITHIUM COMPOSITE OXIDE, ELECTROCHEMICAL DEVICE AND LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/067497
Kind Code:
A1
Abstract:
The present invention is a method for regenerating a lithium composite oxide, which is characterized by comprising: a step for preparing a lithium composite precursor from which some lithium has been electrochemically or chemically extracted; and a step for having the lithium composite precursor, from which some lithium has been extracted, react with a lithium compound. Consequently, the present invention provides a method for regenerating a lithium composite oxide, which is capable of regenerating, at low cost, a lithium composite oxide that enables the achievement of excellent charge/discharge capacity if used as a positive electrode active material of an electrochemical device.
