Controlled Synthesis of Ultrafine β-Mo₂C Nanoparticles Encapsulated in N-Doped Porous Carbon for Boosting Lithium Storage Kinetics.

ABSTRACT: Rational construction of anode material architecture to afford excellent cycling stability, fast rate capacity, and large specific capacity is essential to promote further development of lithium-ion batteries in commercial applications. In this work, we propose a facile strategy to anchor ultrafine β-Mo₂C nanoparticles in N-doped porous carbon skeleton (β-Mo₂C@NC) using a scalable salt-template method. The well-defined and abundant hierarchical porous structure of β-Mo₂C@NC can not only significantly enhance the electron/ion transfer but also markedly increase the specific surface area to effectively expose the electrochemically accessible active sites. Besides, the N-doped carbon matrix can turn the d-orbital electrons of the Mo to boost the electron trans
