ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, MANUFACTURING METHOD THEREFOR, ANODE FOR LITHIUM SECONDARY BATTERY COMPRISING SAME, AND LITHIUM SECONDARY BATTERY |
摘要 |
A negative active material for rechargeable lithium secondary batteries, a method of preparing the same, and a rechargeable lithium secondary battery including the same are disclosed. The negative active material includes a core including a lithium titanium oxide of Formula 1, and a coating layer positioned on a surface of the core and including an acid anhydride physisorbed onto the core, and thus can be useful in inhibiting battery side reactions and gas generation and improving battery performance since moisture formed during a redox reaction is effectively absorbed into a surface of the negative active material.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ[Formula 1]€ƒ€ƒ€ƒ€ƒ€ƒLi x Ti y O 4 In Formula 1, x and y are as defined in the detailed description. |
