Abstract: A durable lithium metal polymer battery with extended cycle-life is designed by exploiting cross-linked poly(trimethylene carbonate) (PTMC) electrolytes and LiNi0.6Mn0.2Co0.2O2 (NMC622) with well-defined protectivecoating (0.5 wt% of LiNbO3 on the surface layer, <5 nm thickness). The presented materials demonstratefeasibility of faster cycling at rates of 1C and 2C at temperatures of 40 and 60 ◦C, exhibiting prominent capacityretention of 91% and 80% SOH (state of health) after 500 cycles. At higher cross-linking densities, the introducedquasi-solid polymer electrolytes afford good cycling performance and sufficient suppression of high surface arealithium depositions as well as improved ability of solvent entrapment, hence reflecting a considerable stepforward towards achieving all solid-state polymer-based cells.
