Abstract: An advanced organic electrode material based on 5,6,11,12,17,18-hexaazatrinaphthylene (HATN) was synthesized. The developed poly-HATN demonstrated exceptional promise for potassium-ion batteries, exhibiting a stable discharge capacity of 150 mAh g⁻¹ and a near-perfect Coulombic efficiency of approximately 100%. These results highlight its potential as a high-performance and sustainable electrode material for next-generation energy storage systems.

Keywords: poly-HATN, hexaazatrinaphthylene, lithium-ion battery, potassium-ion battery, 1,2-dimethoxyethane, discharge capacity, charge–discharge cycling, quantum chemical modeling.
