Are hydrogen carrier polymers inspired by reversible charge storage with bistable redox-active polymers?

Here, we focus on the design principles of hydrogen carrier polymers inspired by reversible charge storage with bistable redox-active polymers. The search for hydrogen carrier polymers has been focused on changes in the properties of redox polymers during charging.

Can polymer dielectrics be used as energy storage media?

Polymer dielectrics are considered promising candidate as energy storage media in electrostatic capacitors, which play critical roles in power electrical systems involving elevated temperatures, such as hybrid electric vehicles, oil & gas exploration, aircraft, and geothermal facilities 1, 2, 3, 4, 5, 6.

Is charge storage possible in organic polymers?

There has been a great deal of research on electrode active materials comprising organic polymers, and many review articles have been published [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13], although the idea of charge storage in polymers has been around for a long time.

What is reversible charge storage with polymers?

Reversible charge storage with polymers is achieved by redox “bistability” and exchange reactions. Redox bistability is a feature of electrochemical reversibility, which refers to the properties of redox pairs in which both the reduced and oxidized states are chemically robust and do not fade during substantial storage periods.

Why is polymer encapsulation important in thermal energy storage systems?

Polymers play an important role in thermal energy storage systems. They are utilized to enhance stability, efficiency, and overall performance by acting as encapsulating matrix materials or composite components [53, 54]. Polymeric encapsulation provides an excellent opportunity to stabilize PCMs within a composite that has a unique structure.

Does reversibility of charge storage occur in nonconjugated polymers?

In this review, we show that reversibility of charge storage occurs in polymers with bistable redox-active groups populated in the repeat units of a nonconjugated backbone, especially when an electron self-exchange reaction spreads throughout the polymer.
