Efficient faradaic supercapacitor energy storage using redox-active pyrene- and benzodithiophene-4,8-dione-tethered conjugated microporous polymers

Abstract

Conjugated microporous polymers (CMPs) are intriguing options for a wide range of applications; however, CMP-tethered energy storage devices such as supercapacitors receive relatively little investigation due to limitations in energy...

Wood-based electrolyte with reversible phase transition for smart thermal-shutdown self-protection

“…2,3 An electrolyte is one of the most important components of electrochemical-energy storage devices, playing a crucial part in their electrochemical performance. 4 However, the trade-off between the safety and electrochemical performance of electrolytes limits the further development of energy-storage devices. During fast charge/discharge processes, the accumulation of energy and ions generates a large amount of heat, which increases the internal pressure and temperature, thereby intensifying the transport of ions and forming a “vicious cycle” of rapid ion transport and temperature rise.…”

Heterosporous Phenylpyridine-Based Covalent Organic Framework Microflowers for Highly Selective Sensing of Hydrogen Sulfide

“…However, these structures are prone to distortion or collapse when subjected to long-term cycle testing. , In comparison, organic micro/nanostructures with forceful covalent bonds can efficiently alleviate the strain resulting from volume fluctuations. This, in turn, leads to an improvement in the stability of the overall structure. − Notwithstanding this benefit, the achievement of their synthesis still poses challenges because of the indeterminate structural regularity under solvothermal conditions. , Therefore, the rational manipulation and control of organic micro/nanoflowers hold significant importance. Covalent organic frameworks (COFs) are a new family of crystalline porous organic polymers. − With the advantages of low density, structural diversity, periodic and uniform porosity, enormous surface area, thermal stability, permanent crystallinity, and versatile functionalities, COFs are promising materials for a considerable variety of applications, such as heterogeneous catalysis, gas storage and separation, molecular separations, chemical sensing, energy conversion and storage, semiconductors, and drug delivery. − Nevertheless, most conventional COFs are produced and isolated in the form of microcrystalline powders, hence restricting the efficient exploitation of active sites.…”
