Two-dimensional (2D) nanomaterials have been used for various electrochemical applications, especially in lithium-based batteries (LBs). They have been employed as anodes, cathodes, and electrolyte components. The major classes of 2D nanomaterials, namely ionically conducting anionic- and cationic-layered clays, transition metal dichalcogenides (TMCs), graphene, boron nitrides (BNs), MXenes, and phosphorene have been employed as fillers in polymer electrolytes (PEs). In this respect, this chapter will shine a light on the various types of polymer composite electrolytes (PCEs) that have been investigated so far as Li+-ion-conducting electrolyte membranes, as well as electrode surface protection layers in LBs. Additionally, this chapter will provide a summary of such PE systems as separator/electrolyte membranes in LBs. The first section will introduce the LBs, and the subsequent sections are dedicated to discussions on various types of electrolyte and the significance of PEs. The last section is focused on PCEs based on 2D nanomaterials as fillers and their application as separators and surface protection layers in rechargeable LBs.
