Randomized trial demonstrates high energy and stability in organic lithium-ion battery cathodes, suggesting advanced material design benefits.

This study aims to develop high-performance organic cathodes using a donor-acceptor-donor molecular design to enhance charge transfer efficiency.
Designed and synthesized two organic molecules: PTZBQ with a quinone core and PTZTAB without a quinone core.
Evaluated the electronic structure, electrode kinetics, and charge transfer characteristics through DFT calculations and spectroscopy.
Tested the materials' discharge potential, specific capacity, and cycling stability under various conditions.
PTZBQ exhibits a discharge potential of 3.05 V and a specific capacity of 163.3 mAh g -1 at 0.1 A g -1 .
Demonstrated 77.6% capacity retention at 5 A g -1 and 89.4% retention after 5000 cycles at 1 A g -1 .
Enhanced interfacial charge transfer leads to improved electrode performance and stability.
