Abstract
Organic batteries are well-poised to impact energy sustainability because they can be sourced from earth-abundant feedstocks, are safer to operate, and offer unique form factors.
This talk explores not only how organic batteries function but also how they can be recycled or degraded on demand. The focus is on redox-active polymers as active electrode materials. These polymers, with non-conjugated backbones and redox-active side groups, facilitate charge transfer via a hopping mechanism – inherently coupled with the simultaneous movement of ions, electrons, and solvent molecules.
The presentation will examine how polymer architecture and chemistry influence this coupled charge transfer, highlighting correlations among pendant group spacing, backbone flexibility, and solvent interactions. These findings are applied in full battery cells capable of operating at low temperatures and bearing structural loads. One such dual-ion battery design, with polymer electrodes supported on carbon fiber current collectors, operates efficiently even at –50 °C.
With continued improvements in energy density and cell voltage, organic batteries could address several limitations of today’s lithium-ion systems.
