The organic molecule triphenazino[2,3-b](1,4,5,8,9,12-hexaazatriphenylene) was utilized as a high-performance cathode for potassium-ion batteries. It delivers a high capacity of 350 mA h g−1, exhibits good cycling stability over 600 cycles, and retains 73% of its capacity at an extreme −50 °C, enabling operation under harsh conditions.
