Recent progress in carbonyl-based organic polymers as promising electrode materials for lithium-ion batteries (LIBs)

Abstract

Lithium-ion batteries (LIBs) have been demonstrated as one of the most promising energy storage devices for applications in electric vehicles, smart grids, large-scale energy storage systems, and portable electronics.

Design strategies for organic carbonyl materials for energy storage: Small molecules, oligomers, polymers and supramolecular structures

“…Several comprehensive reviews have covered common design strategies as solutions to this drawback. [20][21][22][23][24][25] We will first turn our attention to the recent trends in high-performance electrode materials with selected examples and highlight the critical rationale to design these electrodes.…”

“…Some of the strategies to form polymers or porous materials by linking redox-active monomers have been reviewed elsewhere. 7,8,10,12,14,20,21,24,50,51 Here, we focus on very recent examples of higher-ordered structures with outstanding performance metrics, and a few representative polymer derivatives.…”

“…Although many of these molecules demonstrate an improved capacity and voltage, they all suffer from poor cycling performance with a fading capacity. Several comprehensive reviews have covered common design strategies as solutions to this drawback 20‐25 . We will first turn our attention to the recent trends in high‐performance electrode materials with selected examples and highlight the critical rationale to design these electrodes.…”

“…This strategy makes use of the general observation that high molecular weight materials are less soluble in electrolytes compared to their low molecular weight counterparts. Some of the strategies to form polymers or porous materials by linking redox‐active monomers have been reviewed elsewhere 7,8,10,12,14,20,21,24,50,51 . Here, we focus on very recent examples of higher‐ordered structures with outstanding performance metrics, and a few representative polymer derivatives.…”

Redox‐Active Porous Organic Polymers for Energy Storage

“…1 During the last two decades, there have been numerous progresses in the development of new energy storage materials. 2 Reversible redox conversions of various materials have been utilized as chemical principles of electrical energy storage. Most related studies have focused inorganic electrode materials such as silicon, tin, carbon materials, metal oxides, and metal chalcogenides.…”
