Transition metal oxides play a key role in attaining cost-effective energy storage systems by exhibiting outstanding electrochemical activity and stability. In this study, a simple, two-step synthesis of CuCo2O4 nanoparticles has been developed based on solvothermal process followed by calcination. Furthermore, the synthesized CuCo2O4 nanoparticles were used as an electrode and electrocatalyst for Li-ion battery and methanol oxidation application, respectively. CuCo2O4 nanoparticles exhibited superior reversible capacity and high-rate capability for Li-ion battery. In addition, these exhibited 75% retention of catalytic activity after 500 cycles for methanol oxidation. Given that the synthesis of CuCo2O4 nanoparticles involves a facile and cost-effective technique, the present approach thus opens a new era to novel materials for large-scale processes in different electrochemical applications.
