Single-Ion Conducting Polymer Electrolytes: Synthesis and Characterization

Abstract

Two classes of alkali metal single-ion conducting polymer electrolytes have been characterized and their conductivities examined.Both polymers are sodium ion conductors. The first class is based upon a tetra(alkoxy)-aluminate counterion incorporated into a polyether network, and the second has a sulfonate counterion covalently bonded to a phosphazene backbone. The temperature dependent and concentration dependent conductivities of these polymers are contrasted. Phosphazene polymers that are anion conductors are also discussed.

Influence of Macrocyclic Ligands on Ion Transport in Solid Polyelectrolytes

“…Polymers were synthesized as described in the literature [4]. The conductivity of polyphosphazene sulfonates increases as the concentration of C-2.2.2 is increased, and reaches a plateau beyond a molar ratio of C-2.2.2 to sodium ion of 1:1 (Fig.…”

“…For both practical applications and fundamental studies, it is desirable to reduce or eliminate the transport of ion aggregates. The latter consideration has led to the synthesis of polyelectrolytes containing polyether groups to achieve a favorable dielectric constant [4,5].…”
