Carbon-coated Li3V2(PO4)3 derived from metal-organic framework as cathode for lithium-ion batteries with high stability

One-pot coating of LiCoPO4/C by a UiO-66 metal–organic framework

“…MOFderived carbon was used as a coating layer for Li 3 V 2 (PO 4 ) 3 cathode material and led to a remarkable enhanced the stability of electrochemistry with high discharge specic capacity at around 113.1 and 105.8 mA h g À1 at a rate of 0.5C and 1C aer 1000 cycles. 26 Herein we report the one-pot synthesis of LiCoPO 4 /C@UiO-66 composite using MW-assisted solvothermal method to enhance the surface of LiCoPO 4 . According to previous studies, 27,28 the metal oxides one of the most widely used coating materials, has been testied that they are highly stable under exertive conditions like extended operational potential window and elevated cycling temperature.…”

Study of palladium and boric acid ion co-doped Li3V2(PO4)3/C cathode material with high performance

“…Strong diffraction peaks can be observed in the XRD patterns, and all patterns are indexed as monoclinic structures with the P2 1 /n space group, which is consistent with previously reported results. [30][31][32] Moreover, no other impurity peaks are found, indicating that the synthesized materials are pure-phase and the carbon coated on the surface of the material is amorphous carbon. It has been proved in many related reports that the carbon lm coated on the surface of the materials can effectively improve the electronic conductivity and the utilization ratio of active substances, and enhance the rate performance of the materials.…”

Progress and Perspective of Metal‐ and Covalent‐Organic Frameworks and their Derivatives for Lithium‐Ion Batteries

“…Other cathodes are synthesized based on MOFs materials or MOF derived structures. For instance, Hu et al [210] . successfully demonstrated MOF (MIL‐101(V)) cathode with outstanding performance as cathode for LIBs.…”

“…Other cathodes are synthesized based on MOFs materials or MOF derived structures. For instance, Hu et al [210] successfully demonstrated MOF (MIL-101(V)) cathode with outstanding performance as cathode for LIBs. The LVP@M-101 sample provided a remarkably improved electrochemical performance with a superior reversible capacity of 113.1 mAh g À 1 at 0.5 C after 1000 cycles, and 105.8 mAh g À 1 at 1 C. Mai et al [211] reported Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2 nanoparticles coated by MOF derived shell NiCo nanodots (LLO@C&NiCo) as cathode for LIBs via a facile method.…”
