Cyano-Driven Solvation Structure Reconstruction and Interfacial Passivation for 4.5 V Solid-State Lithium Metal Batteries.
Solid polymer electrolytes hold great promise for high-energy-density lithium metal batteries, yet their practical implementation is still hindered by sluggish room-temperature Li+ transport and insufficient high-voltage tolerance (i.e., unstable above 4.3 V) especially when coupled with Ni-rich layered cathodes. Herei...
