A small-molecule organic cathode with fast charge–discharge capability for K-ion batteries

Author affiliations

Abstract

Perylene-3,4,9,10-tetracarboxylic diimide (PTCDI, 137 mA h g−1) is initially exploited as a new organic cathode for K-ion batteries. In half cells, it can deliver stable capacities of ∼120 mA h g−1 (600 cycles) at 4 A g−1 and ∼80 mA h g−1 at 10 A g−1. In full cells with a working voltage of above 1 V, PTCDI can display an average capacity of ∼127 mA h g−1 at 50 mA g−1 over 30 cycles.
