“…The concept of single ion conducting electrolyte was proposed thirty years ago [7] but only in recent years has gained serious attention [8,11,32,33,39]. In a single ion conducting electrolyte, anions are anchored on a stationary substance and surrounded by electron withdrawing functional groups.…”

“…Use of low molar mass polyethylene glycol dimethyl ethers (PEGDMEs) as plasticizers (30-40%) in the PEO matrix increased ambient temperature conductivities, but at the cost of significant reduction in the mechanical and interfacial properties [1]. Other approaches to increasing the room temperature (RT) conductivity of polyether electrolytes are by attachment of short-chain PEO oligomers as side chains to flexible [2][3][4][5][6][7][8][9][10] or rigid polymer backbones [11,12], network polyethers [13,14] and inorganic scaffolds [15,16].…”

“…This was clearly seen in comparison of the conductivity of P(ME0 7 -MALi) with that of P(ME07 )/lithium isobutyrate hybrids. 18 In the hi-ionic conductor, conductivity greatly depend on the dissociation energy of added salt. For example, when potassium, sodium or lithium was added to the films, the conductivity for the films was in the order of potassium> sodium> lithium.…”

“…20 We also reported the lithium polymeric solid electrolyte with single-ionic conduction, and the solidstate battery composed of this has been evaluated. 18 As lithium is more expensive than sodium for the application to commercial battery, the sodium single-ionic conductor should be requested. Furthermore, the redox potential of sodium is similar to that of lithium and costs less.…”

ABSTRACT:Poly[oligo(oxyethylene) methacrylate-co-sodium methacrylate] was prepared as a polymeric solid electrolyte which enables sodium single ionic conduction. A methanol solution of the mixture of oligo(oxyethylene) methacrylate and sodium methacrylate was cast and polymerized on a Teflon® plate. The film obtained showed a conductivity of 4.0 x 10-7 Scm -t at 80°C. The conductivity of the films depended on the sodium methacrylate content. Temperature dependence of the conductivity was analyzed as WLF-type behaviour. The ionic conduction mechanism of this film was found to be deeply affected by the segmental motion of the matrix polymer. This was also confirmed by the Vogel-Tammann-Fulcher plot for ionic conductivity.KEY WORDS Polymeric Solid Electrolyte I Sodium Conductor I Dissociation Energy I Thin Film I WLF Behaviour I Polymeric solid electrolytes with high ionic conductivity and good processibility are in serious demand for the development of electronic devices. 1 -3 Many investigations in this field have been carried out, especially on poly( oxyethylene )-alkali metal salts systems.4-13 The authors have prepared polymeric solid electrolytes to satisfy the following requirements, 14 -18 (1) construction of flexible polymer domain in which let carrier ions exist stably, (2) decrease of the T 8 of polymer solid electrolyte in order to increase the mobility of carrier ions, and (3) inhibition of the migration of counter ions. Polymeric solid electrolytes reported previously have already satisfied requirements, (1) and (2). However, the last one (3) has not always been satisfied. A secondary solid-state battery or some application of the solid electrolytes required no anion migration because that caused a serious self discharge.
