Carbonitridation Pyrolysis Synthesis of Prussian Blue Analog-Derived Carbon Hybrids for Lithium-Ion Batteries
ADVANCED SUSTAINABLE SYSTEMS(2021)
Abstract
Cost-effective nanostructured carbon hybrids have received global attention in sustainable energy research due to their stable structure and high conductivity. Herein, the nickel-cobalt nanoparticles embedded carbon nanotube hybrid (NCCH) derived from Prussian blue analogs (PBAs) has been prepared by a carbonitridation pyrolysis process. Simultaneously, the uniform NCCHs interweave to form a conductive structure. The fascinating architecture offers abundant active sites and enhanced electronic conductivity when served as an anode material in lithium-ion batteries. As a consequence, the resulting NCCH exhibits excellent cell behaviors with a high reversible capacity and remarkable rate capability. Equally important, the study provides a unique insight into the development of high-performance carbon hybrids electrodes derived from PBAs.
