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 share of energy-related R&D?

The dark green dots show a similar development for the share of energy-related R&D to total R&D spending. In the late 1970s, energy R&D accounted for over 10% of total R&D, of which more than 50% was allocated to nuclear energy globally.

Will electricity storage benefit from R&D and deployment policy?

Electricity storage will benefit from both R&D and deployment policy. This study shows that a dedicated programme of R&D spending in emerging technologies should be developed in parallel to improve safety and reduce overall costs, and in order to maximize the general benefit for the system.

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 a superconducting magnetic energy storage system?

Superconducting magnetic energy storage (SMES) systems store energy in a magnetic field created by the flow of direct current in a superconducting coil that has been cooled to a temperature below its superconducting critical temperature. A typical SMES system includes a superconducting coil, power conditioning system and refrigerator.

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.
