Hybrid CoMoO3/CoMoO4 nanorods for enhanced lithium-ion battery performance

  • Electrode materials that rely on conversion reactions for lithium-ion batteries (LIBs) possess high energy densities. However, a key issue in their design is bolstering their stability and minimizing volume variations during lithiation and delithiation. Herein, an effective strategy was devised to fulfill the fully reversible conversion reaction for lithium storage in CoMoO4 through the hybridization of CoMoO3. CoMoO3/CoMoO4 with a nanorod structure was synthesized via one-step annealing treatment after a solvothermal process. In such a structure, the CoMoO3/CoMoO4 nanorod can considerably boost mechanical robustness and offer ample space to counteract volume fluctuations throughout successive cycles owing to the cooperative interaction between CoMoO3 and CoMoO4. CoMoO3/CoMoO4 exhibited superior lithium-storage capacity (919.6 mAh/g at 0.1 A/g after 200 cycles) and cycling stability (683.4 mAh/g at 1 A/g after 600 cycles). CoMoO3/CoMoO4 showed a high potential as an anode material for LIBs.
