POMs-based metal-organic frameworks with interpenetrating structures and their carbon nanotube-coated materials for lithium-ion anode applications

The inherent characteristics of abundant, stable, and swift electron transfer make polyoxometalates (POMs) exceptionally suitable for utilization in energy storage applications, particularly in Lithium-ion batteries (LIBs). By immobilizing POMs within metal-organic frameworks, Ag-BTBA-POM was synthesized to address the challenges associated with the low electronic conductivity and solubility of POMs. To enhance the electronic conductivity of POMOFs crystals further, CNT@Ag-BTBA-POM was developed. This carbon composite material exhibits exceptional cyclic stability and electrochemical characteristics, with the discharge specific capacity stabilizing at around 730 mA h g-1 over 100 cycles.
