Anion effects on the properties of OIPC/PVDF composites

Abstract

Organic ionic plastic crystals (OIPCs) are promising solid electrolytes because of their inherent advantages such as non-volatility, non-flammability, good thermal stability, favourable plasticity, and improved electrolyte/electrode interfacial contact. Incorporating nanoparticles...

Mixed ionic and electronic conducting binders containing PEDOT:PSS and organic ionic plastic crystals toward carbon-free solid-state battery cathodes

“…Such large increases of the ionic conductivity in polymer/OIPC composites have been shown in related studies and are explained by the disordering of the crystalline phase of OIPCs. 40 The values of the activation energy for the ionic conductivity are 12.9 kJ mol À1 for C 2 mpyrFSI, in good agreement with recent studies, and 11.4 kJ mol À1 for C 2 mpyrTFSI. 44 It is also worth noting the low values of activation energies of the mixed conductors in this work (Table S1 †), all of them being below 5 kJ mol À1 .…”

“…39 Likewise, several authors have already reported modications in the OIPC crystalline structure when a second component is added. 39,40 Finally, the X-ray spectrum of 70/30 P:PSS/C 2 mpyrTFSI does not show sharp peaks related to the crystalline structure of the OIPC with peaks at 6.2 (d ¼ 14.1 Å) and 12.4 (d ¼ 7.2 Å) related to the side-by-side packing d 100 and the d 200 reection, respectively. Different crystalline structures have been dened for PEDOT:PSS called type I (non-orientated) and II (orientated lamellar stacking) with specic spacings of 21 and 12 Å, respectively.…”
