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 over 100 cycles.

具有互穿结构的基于聚甲醛的金属有机框架及其用于锂离子阳极应用的碳纳米管涂层材料


丰富、稳定和快速电子转移的固有特性使多金属氧酸盐（POM）特别适合在储能应用中使用，特别是在锂离子电池（LIB）中。通过将 POM 固定在金属有机框架内，合成了 Ag-BTBA-POM，以解决与 POM 的低电子电导率和溶解度相关的挑战。为了进一步提高 POMOF 晶体的电子电导率，开发了 CNT@Ag-BTBA-POM。这种碳复合材料表现出优异的循环稳定性和电化学特性，在 100 次循环后放电比容量稳定在 730 mA hg 左右。
