NEGATIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERY, NEGATIVE ELECTRODE, AND LITHIUM ION SECONDARY BATTERY INCLUDING THE SAME

The present disclosure relates to a negative electrode active material for a lithium ion secondary battery, a negative electrode, and a lithium ion secondary battery including the same. In the present disclosure, a crown ether-based host material which is a compound allowing selective coordination bonding with a lithium ion and having a similar cavity size to ions is included in the negative electrode active material, thereby suppressing lithium precipitation on the surface of the negative electrode active material to improve high rate charge/discharge characteristics of the battery, and also the crown ether-based host material solution is coated on the negative electrode active material layer of the battery to facilitate migration of lithium ions at high rate to improve an insertion/extraction speed of lithium ions during charge/discharge of the battery.
