This Symposium will focus on new materials, ion transport, novel characterization methods and modeling of the following classes of Polymer Electrolytes.

The label “Polymer Electrolyte” (PE) refers to any macromolecular or supramolecular nano-aggregate system characterized by a significant ionic conductivity, usually considered higher than approximately 10⁻⁷ S•cm⁻¹. This Symposium takes into consideration “Classic Polymer Electrolytes” (Classic PEs) as classified by Gray [Polymer Electrolytes, RSC Materials Monographs, Cambridge, UK] in 1997, and “Hybrid inorganic-organic polymer Electrolytes” (HIO-PE) [Electrochim. Acta, 57, 4-13 (2011)].

“Classic PEs” comprise:

• Class 1. “Polymer electrolytes (PEs)”: macromolecular systems capable of dissolving suitable salts.
• Class 2. “Gel polymer electrolytes (G-PEs)”: these systems are obtained in two steps. First, a salt is dissolved into a polar or ionic liquid to produce an ion-conducting solution; and then, an inert polymeric material is added to bestow an acceptable mechanical stability.
• Class 3. “Plasticized polymer electrolytes (P-PEs)”: P-PEs are obtained by adding small amounts of a solvent characterized by a high dielectric constant or an ionic liquid to the other classes of polymer electrolytes.
• Class 4. “Ionic rubber polymer electrolytes (IR-PEs)”: these systems are produced by adding small amounts of a polymer characterized by a high molecular weight to a low-temperature ionic liquid mixture.
• Class 5. “Ion-conducting polyelectrolytes (IC-Ps)”: these systems consist of macromolecular chains bearing ionic groups chemically bonded to the backbone chains of the host polymers. IC-Ps are single-ion conductors.

“Hybrid inorganic-organic polymer Electrolytes (HIO-PE)” include:

• Class A. “Multi-phase PEs”:
  • Class A1. “(nano) Composite Polymer Electrolytes (CPEs)”: inorganic species such as oxide nanopowders are introduced into Classic PEs to promote ionic conductivity in the resulting multiphasic hybrid system and to improve the chemical, mechanical and electrochemical properties.
  • Class A2. “Organically Modified Ceramics as Polymer Electrolytes (ORMOCERs-APEs)”: these are ion-conducting materials that consist of inorganic and organic nano-domains formed via a sol-gel reaction using organometallic silicon precursors and the basic components of Classic PEs as building blocks.
• Class B. “Mono-phase PE”:
  • Class B1. “3-Dimensional Hybrid Inorganic Organic Networks as Polymer Electrolytes (3D-HION-APEs)”: these are 3D ion-conducting materials, where metal or non-metal atoms act as bridges between macromolecules.
    • B1a. “3D-HION-APE” with “ate” complex structures, e.g., aluminate, borate, etc. (a-3D-HION-APEs).
    • B1b. “3D-HION-APE” with weak anion-trapping sites (w-3D-HION-APEs).
  • Class B2. “Zeolitic Inorganic–Organic Polymer Electrolytes (Z-IOPEs)”. Z-IOPEs are ion-conducting materials where inorganic clusters, formed by the aggregation of two or more inorganic coordination complexes that may be either positively or negatively charged, are bridged by organic macromolecules;
  • Class B3. “Hybrid Gel Electrolytes (HGEs)”. The HGEs are prepared by sol-gel processes starting from inorganic or organometallic precursors bearing an ion-conducting cation and low molecular or macromolecular liquids.

 

Abstracts are solicited in, but not necessarily limited to, the following areas:

• New materials - block copolymers, gels with ionic liquids;
• Single ion/ high transport no. measurements;
• Polymer electrolytes preventing dendritic growth in Lithium batteries;
• Improved porous and dense separators;
• Polymer/ionic liquids interaction;
• Separators and polymer electrolytes for Li/S batteries;

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
