ZCPL-LAGP enables higher initial and retained Li/LFP full-cell capacity than unprotected LAGP.
Caveat: Full-cell comparison includes different cycle counts for final reported capacities; cathode deterioration may contribute to ZCPL-LAGP fade.

Li/ZCPL-LAGP/Li maintains much lower and steadier interfacial resistance than Li/LAGP/Li during 300 h cycling.
Caveat: Resistance values are fitted from equivalent circuits; uncertainty not reported.
3146-3147 · Results; Summary · Figure 3 · Linked to 3 structured results
The ZCPL component remains chemically stable against Li metal during cycling.
Caveat: Based on Co 2p and N 1s XPS consistency; no quantitative post-cycling peak shifts are tabulated.
3146 · Results · Figures S16-S19 · Linked to 3 structured results
The adhesive PEO-based ZCPL coating infiltrates LAGP surface pores/gaps and creates intimate contact, reducing interfacial resistance.
Caveat: Contact improvement is supported by microscopy and EIS fitting; mechanical adhesion is qualitative.

ZCPL protects LAGP from reduction by Li metal, suppressing Li2O2, Ge3+, metallic Ge formation and cracking.
Caveat: XPS comparison is made after electrochemical cycling; exact cycling duration for XPS sample follows symmetric-cell context but is not restated next to every spectrum.

ZIF-67 addition increases ionic conductivity of the polymer interlayer by about one order of magnitude relative to PEO/LiTFSI.
Caveat: Comparison is between composite ZCPL and MOF-free PEO/LiTFSI control with same PEO:LiTFSI ratio; exact ZCPL conductivities at all SI temperatures are not tabulated.
3144 · Results · Figures S5-S8 · Linked to 4 structured results
The microporous structure and ordered channels of ZIF-67 are proposed to promote uniform Li+ flux at the interface, improving long-term plating/stripping stability.
Caveat: Uniform flux is inferred from electrochemical stability and MOF porosity rather than directly imaged Li flux.
3146 · Results · Figure 3d · Linked to 3 structured results
Li+ transport in ZCPL is assigned to hopping through amorphous PEO regions, aided by ZIF-67/PEO interactions and ZIF-67 porosity; LAGP conducts by defect-assisted diffusion in NASICON channels.
Caveat: Mechanistic assignment is interpretive and supported indirectly by DSC, porosity, conductivity, and literature; no direct Li+ diffusion measurement is reported.
