Abstract
Provided are reduced acylated graphene oxide as an electrode active material and a method for preparing the same. By the method for preparing reduced acylated graphene oxide according to the present invention, a negative electrode active material for a lithium secondary battery having stable activity and a high battery capacity may be prepared with a simple and low-cost process. In addition, the active material prepared by the preparation method has low resistance, a high battery capacity, and improved rate-limiting characteristics while having stable cycle characteristics.
