In this study, CuO nanorods and CuO/graphene aerogel (GA) composites are investigated as potential anode materials. CuO nanorods were synthesized by chemical precipitation, while the CuO/graphene aerogel hybrid was prepared by the aerogel method. Structural, morphological and electrochemical characterizations were performed, which showed enhanced performance of the CuO/GA hybrid composite. This composite structure retained 90 % of its capacitance after 500 cycles, significantly outperforming the pure CuO electrode. The unique properties of CuO's high theoretical capacity combined with graphene's superior conductivity lead to enhanced lithium storage and structural resilience. This study examines CuO nanorods combined with graphene aerogels to leverage graphene exceptional conductivity and 3D porous structure for improved performance.
