Highlights

• Janus quasi-solid electrolyte membranes with asymmetric porous structure were constructed, showing a high σ_Li+ of 1.5 × 10^-4 S cm^-1 and a high t₊ of 0.71.

• The solvation structures and ion transport dynamics in nanopores have been deciphered, manifesting a concentrated electrolyte-like structure and regulated transport behaviors.

• Quasi-solid NCM 622||Li cells have been demonstrated to stably cycle for 200 cycles at 1 C, and pouch cell has shown high tolerance for abuse.
