ANODE ACTIVE MATERIAL, NON-AQUEOUS LITHIUM SECONDARY BATTERY INCLUDING THE SAME, AND MANUFACTURING METHOD THEREOF |
摘要 |
The disclosure relates to an anode active material, a non-aqueous lithium secondary battery, and a manufacturing method thereof. The anode active material of this disclosure comprises a carbon-based material, and a coating film formed on the surface of the carbon-based material by performing heat treatment using an ammonia-based compound. The coating film may be formed on the surface of the carbon-based material through a thermal decomposition method using 10% or less by weight of the ammonia-based compound with respect to the carbon-based material. Since the surface of the carbon-based material is thermally treated using the ammonia-based compound, side reaction of the carbon-based material with an electrolyte at the surface thereof can be suppressed and structural stability can be enhanced, thereby improving battery lifespan and high-rate capability of a non-aqueous lithium secondary battery.
