Abstract

A perylene diimide containing side-chain amines (PDIN) was studied as an organic cathode for application in lithium batteries, showing a high capacity of 174 mA h g⁻¹. The chemical structures, experimental results, and calculation analyses verify that PDIN performed a 4-electron redox reaction jointly involving its C [double bond, length as m-dash] O and side-chain amine groups. This study promotes the development of organic cathodes with multi-electron redox reactions.
