6 FAQs about [Poly energy storage]

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.

What is the difference between charging a polymer and charge storage?

Charging a polymer means that a pristine electroneutral redox polymer is converted to a polyelectrolyte via a redox reaction, while charge storage with polymers represents charging of a layer of the redox polymer placed on a current collector, which is accompanied by the incorporation or expulsion of electroneutralizing counterions.

How reversible energy is stored in rechargeable organic batteries?

Electric energy is stored in rechargeable organic batteries by using polymers as electrode-active materials for reversible charge storage. Hydrogen is reversibly stored in hydrogen carrier polymers through the formation of chemical bonds.

What is the charge storage density of PTMA?

The charge storage density for PTMA is CR = 1/0.00249 = 402 C/g = 112 mAh/g. The n -type two-electron charging of poly (2-vinyl-9,10-anthraquinone) (PVAQ) gives a higher charge storage density of CR = 229 mAh/g, using fwR = 234 g/mol for the chemical formula of C 16 H 10 O 2 per repeat unit and n = 2.

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.
