• A novel CoMoO3/CoMoO4 hybrid nanorod anode was synthesized via a simple solvothermal and annealing process, achieving a high reversible capacity of 919.6 mAh/g after 200 cycles at 0.1 A/g.
• The hybrid structure exhibits excellent long-term cycling stability, retaining 683.4 mAh/g after 600 cycles at 1 A/g, attributed to enhanced mechanical robustness and volume change accommodation.
• The synergistic interaction between CoMoO3 and CoMoO4 promotes fully reversible conversion reactions, addressing the sluggish kinetics and poor stability of pure CoMoO4.
• This work provides a promising strategy for designing high-performance conversion-type anode materials for next-generation lithium-ion batteries.
