Abstract

Abstract : The Cover Feature shows that the discharge voltage of conjugated organic battery cathode materials could be increased by diluting the electron density in the π‐conjugated skeleton. The background is composed of a positive battery cap and hexagonal organic molecules, indicating organic batteries. The rocket‐like molecules are four representative models used to demonstrate voltage tailoring. The smoke rings represent the diluted electron density of the molecule, and their size is correlated to the degree of dilution. The assembly line in the lower‐right corner shows that ideal molecules could be experimentally designed and synthesized for organic batteries if proper molecular design strategy was applied.
