Hydrogel which has flexible, stretchable, and self-healing properties are captivate a lot of attention for the wearable and portable energy storage devices. However, the design of hydrogel that own high mechanical properties as well as high ionic conductivity remain a big challenge. Herein, by introducing mesoporous silica nanoparticles to poly (lithium acrylate)-based hydrogel we are achieving high ionic conductivity ~ 10-3 S/cm at room temperature while maintain high stretchability ~ 2000%. The prepared hydrogel also exhibits a self-healing property after cut and heal for 90 minutes due to the intramolecular and intermolecular hydrogen bonding of hydrogel. We thoroughly investigate the chemical structure, morphology, mechanical and electrochemical properties of hydrogel using Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), universal testing machine (UTM), and electrochemical impedance spectroscopy (EIS).
