The solid-state electrolytes used in lithium-ion batteries belong mainly to two classes of material: lithium-ion-conductive polymers and inorganic lithium-ion-conductive ceramics.
SEs fulfil a dual role in solid-state batteries (SSBs), viz. i) being both an ionic conductor and an electronic insulator they ensure the transport of Li-ions between electrodes and ii) they act as a physical barrier (separator) between the electrodes, thus avoiding the shorting of the cell. Over the past few decades, remarkable efforts were dedicated to the development of
