a Cyclic voltammograms of PVDF10 and CARR10 samples recorded between 1.7 and 2.8 V (vs Li/Li+) at a scan rate of 0.1 mV·s−1,, (b) cyclic voltammograms of the different carrageenan-containing samples recorded between 1.7 and 2.8 V (vs Li/Li+) at a scan rate of 0.1 mV·s–1,, (c) complex-plane impedance diagrams with the corresponding CNLS fitting of PVDF10 and CARR10 samples measured between 100kHz and 10 mHz, (d) complex-plane impedance diagrams with the corresponding CNLS fitting (solid lines) of the different carrageenan-containing samples measured between 100 kHz-10 mHz. The inlays show the magnified high-frequency regions in both cases.
