"P(PDEM-D4)-CSE exhibits high ionic conductivities (i.e., 4.0 × 10−5, 1.68 × 10−4, and 5.73 × 10−4 S·cm−1 at 30°C, 60°C, and 100°C, respectively). CSE can induce more uniform, reversible Li plating/stripping behaviors, mainly owing to formation of compatible solid electrolyte interface... enables long-life 4.4 V-class solid-state LMBs based on LiCoO2 cathode... 79.7% capacity retention and 99.74% average Coulombic efficiency after 500 cycles at 0.5 C rate"
