Abstract Ionogels are widely studied as promising ionic thermoelectric (i‐TE) materials to harvest low‐grade waste heat into electrical energy due their huge thermopower and good conductivity, providing a feasible way sustainable development. Herein, p‐type i‐TE cellulose ionogel (CIG) based on Soret effect is prepared by dissolving in an liquid (IL) subsequent water‐absorbing induced gelation. Its morphological structure IL distribution intuitively investigated through cryo‐focused ion beam‐scanning electron microscope. Experimental characterizations molecular dynamic simulation studies elucidate that the regulation of water content induces hydration 1‐butyl‐3‐methylimidazolium cation swelling CIG, which greatly promotes ions diffusion expands difference mobility between anions cations. The proposed CIG exhibits superior properties: conductivity 51.2 mS cm −1 , Seebeck coefficient 20.7 mV K figure merit zT i 2.36 at 30 °C, respectively. A CIG‐based device designed assembled demonstrate its great potential for wearable body heat‐to‐electricity conversion. skeleton completely biodegradable nature used recyclable reusable, green strategy harvesting.

Abstract Cellulose ionogels gain considerable attention for their application in flexible electronic devices. However, achieving an optimal balance between mechanical and properties remains a challenge. Here, high‐performance cellulose ionogel is reported through strengthening the hydrogen bond network weakening electrostatic interactions within molecular framework. The resulting ionogels, under single network, exhibit impressive tensile strength of 3.5 MPa ionic conductivity 14.3 mS cm −1 . Additionally, they demonstrate wide voltage window up to 3.0 V high thermal stability, withstanding temperatures exceeding 120 °C. Serving as all‐solid electrolytes, contribute construction integrated energy storage devices, remarkable density over 60 Wh kg⁻¹ demonstrating significant cycle with capacitance retention rate 97% after 10 000 charge–discharge cycles. With robust electrical properties, well‐positioned offer innovative insights next generation flexible,
