“…The porosity of PEO‐01PS surface is nearly 20% lower than PEO‐0PS (Figure 1i), where the pores are mainly formed by dielectric breakdown and gas evolution. [ 23 ] Additionally, the internal pore distribution of PEO‐xPS membranes is shown in Figure S11 (Supporting Information), the PEO‐0PS are revealed to possess more pores and gaps inside using the reconstructed stack of cross‐sectional slices. Meanwhile, according to the simulation calculation of the internal pores after cutting 1000 slices (Figure 1 h), it is found the average porosity of PEO‐0PS (73.0%) is extensively higher than PEO‐01PS (48.7%).…”

Polyethylene oxide (PEO)‐based solid polymer electrolytes (SPE) have garnered recognition as highly promising candidates for advanced lithium‐metal batteries. However, the practical application of PEO‐based SPE is hindered by its low critical current density (CCD) resulting from undesired dendrite growth. In this study, a PEO‐based SPE that exhibits an ultra‐high CCD (4 mA cm−2) is presented and enhanced lithium ionic conductivity through the incorporation of small amounts of P2S5 (PS). The crystalline Li2O‐rich and P/S‐containing solid electrolyte interphase (SEI) is revealed by cryo‐electron microscope (cryo‐EM) and Time of flight secondary ion mass spectrometry (TOF‐SIMS), which inhibits dendrite growth and adverse reactions between SPE and reductive lithium, thus offering a spherical growth behavior for dendrite‐free lithium metal anode. Consequently, utilizing the PS‐integrated SPE, a Li‐Li symmetric cell demonstrates reduced resistance during operation, enabling stable cycles exceeding 200 hours at 0.5 mA cm−2 and 0.5 mAh cm−2, a stringent test condition for PEO‐based electrolytes. Moreover, a Li/SPE/LiFePO4 (LFP) pouch cell exhibits 80% capacity retention after 100 cycles with 50 µm Li and 30 µm PEO electrolyte, showcasing its potential for practical applications.
