Abstract Lithium-ion (LiBs) and sodium-ion batteries (NaBs) are vital for energy storage but suffer at low temperatures due to electrolyte solidification, low ionic conductivity, and high interfacial resistance. Organic electrode materials offer advantages such as low cost, tunable structures, and flexibility, yet are limited by poor conductivity and solubility. Here, we report a facilely synthesized small-molecule organic cathode, PMDI-2AQ , derived from pyromellitic dianhydride and 2-aminoanth
