Solvent-free quasi-solid polymer electrolyte with a high dielectric constant for stable lithium metal anodes

Enhancing interfacial Li+ transport and dielectric properties in poly(ethylene oxide)-based all-solid electrolytes via inactive g-C3N4 nanosheets filler incorporation

“…These "bright spots", with higher dielectric permittivity, can serve as the nano-capacitors that can act as a "shock absorber" for the lithium plating and striping to inhibit any sudden changes in the lithium flux. Meanwhile, at the electrolyte-anode interface, a higher dielectric region derived from the g-C 3 N 4 additive particles can result in a dipole layer arranged near the anode surface that can also guide the lithium ions into a more uniform path [60]. LiFePO 4 /Li all-solid-state batteries were assembled to evaluate the performance of the electrolytes.…”
