Abstract
An electrode active material for a lithium secondary battery using a heterocyclic compound and a lithium secondary battery including the same are provided. The heterocyclic compound, which is useful as a cathode or anode active material, includes a six-membered ring and a five-membered ring containing one or more elements selected from the group consisting of nitrogen (N), oxygen (O) and sulfur (S), and the heterocyclic compound is configured such that two pairs of carbons which form double bonds with nitrogen atoms contain a functional group linked by a single bond, thus exhibiting redox activity.
