Abstract
The present disclosure relates to a reduced graphene oxide for a secondary battery, a method for preparing the same, an electrode using the same, and a secondary battery using the same. Specifically, the reduced graphene oxide is a powdery two-dimensional crystalline reduced graphene oxide satisfying Relational Expressions 1 to 3 shown below. [Relationship 1] 1≤TQ≤5 [relational expression 2] 100≤EQ≤1,000 [Relationship 3]1≤BETQ≤100. In Relational Expression 1, TQ represents the thickness (nm) of the reduced graphene oxide. In Relational Expression 2, EQ represents the electrical conductivity (S/cm) of the reduced graphene oxide. In Relational Expression 3, BETQ represents the specific surface area (m2/g) of the reduced graphene oxide.
