In article number 2002416, Weidong Zhou and co‐workers develop a poly‐oxalate/poly‐ether dual‐polymer‐electrolyte system to electrochemically tolerate both high potential cathodes and low potential anodes, respectively. Combined with a cathode coating, the interfacial decomposition of poly‐oxalate in LiNi 0.6 Mn 0.2 Co 0.2 O 2 (NMC622) is suppressed. With the help of this strategy, the cycling performance of all‐solid‐state Li‐metal/NMC622 cells is significantly improved.
