Title:
POSITIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERY, POSITIVE ELECTRODE, FOR SECONDARY BATTERY, COMPRISING SAME, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/095068
Kind Code:
A1
Abstract:
The present invention provides a positive electrode active material for a secondary battery, a positive electrode, for a secondary battery, comprising same, and a secondary battery. The positive electrode active material comprises: a core which comprises lithium composite metal oxide; and a surface treatment layer which is disposed on the surface of the core, wherein the surface treatment layer comprises a porous coordination polymer having central metal ions coordinate-bonded to organic ligands. Therefore, the present invention enables high electrode density during preparation of the electrode, thereby greatly enhancing battery characteristics.
