An Insensitive Energetic Material as a High‐Performance Organic Cathode Toward Dual‐Mode Batteries

ABSTRACT Bridging long‐duration electrochemical power delivery with on‐demand, ultrafast explosive output within a single material could enable next‐generation mission‐critical power systems. Here, we report an insensitive yet energetic small molecule, 4,4′,6,6′‐tetramino(azo)‐1,3,5‐triazine (TAAT) as a high‐performance organic cathode for batteries with dual‐mode energy release. Guided by a modular “function‐by‐design” strategy, TAAT concurrently exhibits low solubility, reversible Li + storage, triggerable explosive output, and high insensitivity. In lithium batteries, TAAT delivers 215 mAh g −1 with a ≈ 3.0 V discharge plateau and sustains stable cycling over 700 cycles; TAAT||Li pouch cells power a mini quadcopter. Beyond electrochemistry, TAAT exhibits a detonation velocity of 7505 m s −1 and detonation pressure of 18.4 GPa, while remaining thermally and mechanically insensitive (T d ≈ 327 °C; impact >40 J; friction >360 N). The energetic response can be initiated by hot wire, laser, or detonator stimuli. These results establish TAAT as a proof‐of‐concept dual‐mode energy‐release material, advancing mission‐tailored battery technologies.
