Lithium and potassium batteries using promising organic electrode material based on hexaazatrinaphthylene

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
