This study presents a comparative analysis of Co₃O₄/graphene and MnO₂/graphene hybrid materials as anode candidates for lithium-ion battery applications. Both composites were synthesized via a facile hydrothermal method, aiming to leverage the high theoretical capacities of transition metal oxides and the exceptional electrical conductivity of graphene. Structural, morphological, and electrochemical characterizations were conducted to evaluate their lithium storage performance. Results indicate that Co₃O₄/graphene exhibits superior specific capacity, rate capability, and cycling stability compared to MnO₂/graphene, attributed to its enhanced electron transport and structural robustness. The findings provide valuable insights into optimizing metal oxide/graphene hybrids for next-generation lithium storage devices.
