Increasing ionic conductivity in polymer electrodes using oxanorbornene

چکیده
Pendant polymer-based organic electrodes consisting of redox-active quinones are promising for the next generation rechargeable batteries owing to their fast redox kinetics and structural diversity design. Many commercially available norbornene monomers have been popular choices preparing pendant polymer electrodes, since these enable numerous synthetic routes attaching groups. However, often suffer from sluggish lithium-ion mobility at both electrode–electrolyte interface within bulk electrode because poor ionic conductivity. This can lead low cycling stability rate capability. In this study, we design compare performance poly(norbornene) poly(oxanorbornene) electrodes. The additional oxygen in repeat unit facilitates conduction Li-ions, resulting improved relative counterparts. Specifically, higher reversible capacities achieved high current densities initial capacity is better retained during prolonged tests. Unlike previous strategies increase conductivity our involves minimal steps only contributes a small redox-inactive mass, offering versatile platform high-performance materials.
