Flexible and super-stretchable Gel Polymer Electrolytes (GPEs) are widely envisioned to be promising materials for the next-generation flexible or stretchable energy storage systems such as lithium ion batteries and supercapacitors. However, the GPEs have natural limitation such as poor mechanical property for structural applications. Here, the Lithium Polyacrylate (PAALi)-based GPE hydrogels are crosslinked with vinyl silica nanoparticles (VSNP), using Di-water as medium, by one step thermal curing process in nitrogen atmosphere. Lithium acrylate monomers are selected to maximize ionic conductivity, and VSNP can provide mechanical property to stand stress during stretching. We investigated the role of VSNP on ionic conductivity, mechanical property, and morphology using dielectric spectroscopy, universal testing machine, and field-emission electron microscopy, respectively. |
