TL;DR: In this article, a new type of tailor-made polymer electrolyte based on ionic liquids and polymeric ionic liquid analogues has been prepared by mixing 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonimide) and poly[1-vinyl-ethyl-imidazolate] bearing similar counter-anions, and the ionic conductivity of all these polymer electrolytes varies between 10 −2 and 10 −5 ǫcm −1 at room temperature.

Journal ArticleDOI
TL;DR: In this paper, the anion and cation diffusion coefficients suggested that the cation was the dominant charge carrier and that the motion was largely independent of the anions, and showed that the increased conductivity was attributed to an increase in the number of charge carriers as a result of decreased ion association.

Abstract: To understand the basic properties of lithium secondary batteries which consist of nonflammable and nonvolatile room-temperature ionic liquid electrolytes, we examined the ionic conductivity, electrolyte/electrode interfacial resistance, and charge-discharge rate characteristics by varying the lithium salt concentration in the room-temperature ionic liquid, lithium salt binary electrolytes. By using a modified imidazolium cation-based room-temperature ionic liquid as an electrolyte, the lithium secondary batteries achieved a stable charge-discharge operation of more than 100 cycles (cathode LiCoO 2 , anode lithium metal, voltage region 3.0-4.2 V, current density 1/8 C). Moreover, we found that an optimal lithium salt concentration exists for obtaining an excellent battery rate performance, which depends on delicate balances in several factors, such as ionic conductivity (viscosity), interfacial resistances at the LiCoO 2 cathode/electrolyte interface, and the lithium metal anode/electrolyte interface.
