Figure 15. (A) Schematic process of creep-enabled Li deposition/stripping in an MIEC tubular matrix, where Coble creep dominates via interfacial diffusion along the MIEC/Libcc incoherent interface; (B) Charge/discharge profiles at 0.1 C; (C) cycling life of the all-solid-state Li-pre-deposited MIEC/SE/ LiFePO₄ batteries. The magenta (capacity) and blue (CE) colors indicate the use of 3D MIEC tubules on Pt foil as a Li host, the discharge capacity of which reaches 164 mA h g^-1 at 0.1 C and 157 mA·h·g^-1 at 0.2 C, while the green color indicates the use of 2D carbon-coated Cu foil as a Li host^[77].
