Abstract: Lignin gel-based electrolyte is disclosed. The lignin gel-based electrolyte includes a lignin polymer network containing lignin molecules and a crosslinking agent to crosslink the lignin molecules; and liquid electrolyte contained within the lignin polymer network. The lignin gel-based electrolyte may have high ionic conductivity and maintain excellent mechanical stability.

Abstract: A dextrin-DADMAC based double network polymer gel electrolyte is disclosed. The gel electrolyte includes: a first polymer network having a network structure in which linear main chains including diallydimethylammonium chloride (DADMAC) monomers are crosslinked with each other via N,N-methylenebisacrylamide; a second polymer network including a dextrin polymer chain, and entangled with the first polymer network to form a double network composed of the first and second polymer networks; and a liquid electrolyte supported inside the double network composed of the first and second polymer networks. In addition, mechanical properties of the polymer gel electrolyte are improved via an ionexchange reaction between the polymer gel electrolyte and a salt.
