## Description

- description: We developed a facile one-pot method for fabricating physical gels
    consisting of ultrahigh molecular weight (UHMW) polymers and highly concentrated
    lithium salt electrolytes. We previously reported physical gels formed from the
    entanglement of UHMW polymers by radical polymerisation in aprotic ionic liquids.
    In this study, we found that the molecular weight of methacrylate polymers formed
    by radical polymerisation increased with the concentration of lithium salts in
    the organic solvents. Consequently, the synthesis of UHMW polymers with a high
    monomer conversion was achieved at very low initiator concentrations, leading
    to the formation of physical gels in highly concentrated electrolytes by the chain
    entanglement of UHMW polymers. The viscoelastic and mechanical properties of the
    UHMW gel electrolytes and their self-healing properties were investigated in detail.
