TL;DR: The relationship between ionic conductivity and morphology of single-ion-conducting poly(ethylene oxide)-b-polystyrenesulfonyllithium(trifluoromethylsulfonyl)imide (PEO-PSLiTFSI) diblock copolymers was studied by small-angle X-ray scattering and ac impedance spectroscopy as discussed by the authors.
Abstract: A significant limitation of rechargeable lithium-ion batteries arises because most of the ionic current is carried by the anion, the ion that does not participate in energy-producing reactions. Single-ion-conducting block copolymer electrolytes, wherein all of the current is carried by the lithium cations, have the potential to dramatically improve battery performance. The relationship between ionic conductivity and morphology of single-ion-conducting poly(ethylene oxide)-b-polystyrenesulfonyllithium(trifluoromethylsulfonyl)imide (PEO–PSLiTFSI) diblock copolymers was studied by small-angle X-ray scattering and ac impedance spectroscopy. At low temperatures, an ordered lamellar phase is obtained, and the “mobile” lithium ions are trapped in the form of ionic clusters in the glassy polystyrene-rich microphase. An increase in temperature results in a thermodynamic transition to a disordered phase. Above this transition temperature, the lithium ions are released from the clusters, and ionic conductivity incre...

TL;DR: In this article, the authors showed that both cation and anion are mobile in the plastic crystal phase of succinonitrile and showed the possibility of creating solid state electrolytes based on plastic crystalline solvents where the matrix itself is neutral and hence not intrinsically conductive.

TL;DR: In this paper, an imidazolium cation structure was tethered with an anionic site to form so called zwitterionic salt, which was used as a nonvolatile polar solvent for guest salts.

TL;DR: The applicability of Li3OCl as a solid electrolyte for Li‐ion batteries is demonstrated and a significantly enhanced ionic conductivity of 2.0 × 10−4 S cm−1 at room temperature is achieved.
Abstract: Antiperovskite Li3OCl superionic conductor films are prepared via pulsed laser deposition using a composite target. A significantly enhanced ionic conductivity of 2.0 × 10-4 S cm-1 at room temperature is achieved, and this value is more than two orders of magnitude higher than that of its bulk counterpart. The applicability of Li3OCl as a solid electrolyte for Li-ion batteries is demonstrated.

TL;DR: In this paper, the properties of ceramic and polymer electrolytes are reviewed and a comparison of the results reported in the literature for different electrolyte materials is provided. But the focus is on discussion of the ionic conductivities.
