"characteristics of both inorganic and organic electrolytes improve stability... introducing O atoms to vitrify LiAlCl4/NaAlCl4, ionic conductivity at room temperature improved 3 orders magnitude (~1 mS cm-1 at 30°C) for both Li+ and Na+... polymer-like mechanical properties enable pressure-less Li- and Na-based solid-state batteries (< 0.1 MPa), low-melting-temperature (< 160°C) allows electrolytes infiltrate electrode materials with 4.3 V cathodes...  electrolyte deformability facilitates scale-up thin films via rolling process"
