Polymers for Reversible Hydrogen Storage Inspired by Electrode-active Materials in Organic Batteries

Redox-active polymers with electrochemical reversibility and rapid electrode reaction rates are employed to develop organic electrode-active materials in batteries, based on their selfexchange reactions polymer layers. Negative charging of the electroneutral redox results a significant increase basicity allow protonation each redox-active site polymer. Since most hydrogenated products no longer redox-active, aprotic battery electrolytes avoid hydrogenation batteries. On other hand, compounds that undergo reversible hydrogenation, such as toluene yield methylcyclohexane, have been studied hydrogen storage materials. However, gas usually proceeds via highly energy consuming process. We anticipated electrolytic molecules would provide much simpler found ketone-containing stored process presence water at room temperature. The resulting alcohol evolved by warming under mild conditions an iridium catalyst. hydrogenation/dehydrogenation cycle was accomplished throughout layer, meaning all ketone groups were equilibrated according > C = O + H2 ⇄ CH-OH extended various types polymer, providing many carrier new class energy-related functional polymers. easy handling moldable nature indicate feasibility applying them pocketable carriers.
