Figure 6. Performance of battery with different separators: (A) Polarization potential voltage-time curves of the Li//Li symmetric cells with PP-blended PEO_60w/PCL_5w separator and PP separator; (B) C-rate capability of the cells with PP-PEO_60w and PP-PEO_60w(EO:Li⁺ = 8:1) separators (1-5C); (C) Cycle stability of the cells with PP-PEO_60w(EO:Li⁺ = 8:1) separator (thickness is 1 μm and 2 μm); (D) C-rate capability of the cells with PP, PP-PEO_60w, PP-PCL_5w and PP-blended PEO_60w/PCL_5w separators (1C-5C); (E) Cycle stability of the cells with PP, PP-PEO_60w (EO:Li⁺ = 8:1), PP-PCL_5w and PP-blended PEO_60w/PCL_5w separators; (F) Charge–discharge curves of Li/PP-blended PEO_60w/PCL_5w separator/LiFePO₄ at different cycles.
