Pressure‐Driven Structural Distortion in Cold Sintered LiFePO4|Li1.3Al0.3Ti1.7(PO4)3 Composite Solid Electrolyte Bilayers

open access: yesBattery Energy, Volume 5, Issue 2, March 2026.
Cold sintering pressure critically affects LiFePO4‐composite solid electrolyte bilayers' performance. High pressure (720 MPa) causes lattice distortions and irreversible phase changes, impairing lithium diffusion and cycling stability, while lower pressure (300 MPa) preserves structure and enables superior battery performance.
