Organic electrode materials for fast-rate, high-power battery applications

Abstract

The development of new battery materials with fast charging/discharging capabilities is necessary to meet the growing demands of modern technologies. While counter ion transport in inorganic materials (generally by de/intercalation) currently limits charge/discharge rates in lithium-ion batteries, the weak intermolecular forces in organic materials result in flexible, spacious structures that offer improved ion transport capabilities. Herein, we present the principles which enable fast rate capabilities in organic electrode materials, accompanied by specific literature examples illustrating exceptional rate performances. We discuss approaches to material design which support electron and/or ion transport and the limitations associated with each approach. This review aims to highlight the unique characteristics of organic materials as high-power density electrodes and inspire continued work in the field.
