LITHIUM SECONDARY CELL, ELECTRODE MATERIAL THEREOF AND METHOD OF FABRICATING THE SAME

摘要

The present invention relates to a lithium secondary battery, an electrode material of a lithium secondary battery, and a manufacturing method thereof. The lithium secondary battery has both low manufacturing costs and excellent output properties. For example, provided is the manufacturing method comprises: a first step for preparing a Li_4Ti_5O_12 (LTO) particle having an average particle size at a microlevel; and a second step for thermally treating at least a portion of the LTO particle to be changed as an oxygen-deficient structure.
