Polymer gel electrolytes for secondary aluminium batteries, prepared with the deep eutectic solvent uralumina (urea:AlCl3) and poly(ethylene oxide) of different molecular weight and at different concentrations

[EN] In the videos these properties are illustrated in three different gels: PEO9-5-U150 is a gel prepared with 5 wt% of poly(ethylene oxide) of molecular weight 900000 g/mol. PEO50-1-U150 is a gel prepared with 1 wt% of poly(ethylene oxide) of molecular weight 5000000 g/mol. PEO80-1-U150 is a gel prepared with 5 wt% of poly(ethylene oxide) of molecular weight 8000000 g/mol.
