Method for Synthesis of Zeolitic Imidazolate Framework-Derived LiCoO2/CNTs@AlF3 with Enhanced Lithium Storage Capacity.

Metal-organic framework-derived lithium cobaltate nanoparticles were fabricated by annealing of the ZIF-67 precursor with Li2CO3 under air, followed by homogeneous AlF3 coating and carbon nanotubes (CNTs) wrapping. The as-prepared AlF3-coated LiCoO2/CNTs electrode can act as a potential cathode for enhanced lithium storage at both room temperature and an elevated temperature of 50 °C.
