Abstract Designing organic electrode materials that achieve high energy density without compromising long‐term cycling stability is a grand challenge in energy storage research. Here, this is addressed by introducing a unique dual‐site, dual‐charge carrier mechanism leveraging a multielectron nitro‐triazine trimeric cathode and two non‐metallic charge carriers (NH 4 + and H + ). We present a highly redox‐active and exceptionally stable nitro‐triazine molecule, 2,4,6‐tris(4‐nitrophenyl)‐1,3,5‐triazine (TNPT), featuring nitro and triazine groups that enable multiple redox sites, extended π‐conjugation, strong‐hydrogen bonding affinity, and π–π stacking capabilities. The dual‐redox nitro and triazine groups interact synergistically with NH 4 + and H + in an optimized 3 m NH 4 OTF electrolyte, leveraging tetrahedral hydrogen bonding and Grotthuss/special pair dance proton transfer, boosting fast kinetics and exceptional cycling stability. A nitrogen‐doped graphene oxide(NG)/TNPT nanocomposite delivers an impressive specific capacity of 263 mAh g −1 at 0.1 A g −1 , with excellent cyclic stability‐retaining 97.8% capacity over 10 000 cycles. Furthermore, the metal‐free hybrid full‐cell device, consisting of a nanoporous carbon capacitive anode and the NG@TNPT battery cathode, achieves a remarkable energy density of 45.11 Wh kg −1 , the highest reported for metal‐free energy storage systems to date. This work provides a new design strategy for developing high‐energy, long‐life, metal‐free hybrid energy storage devices.
