Ammonium-Based Plastic Crystals as Solid-State Electrolytes for Lithium and Sodium Batteries.

ABSTRACT: Organic ionic plastic crystals (OIPCs) are a promising class of solid materials composed of organic cations and inorganic anions, increasingly explored for use as solid-state electrolytes (SSEs). These materials offer a safer alternative to conventional carbonate-based electrolytes in lithium and sodium ion batteries. In this study, lithium and sodium salts were incorporated into tetramethylammonium bis(fluorosulfonyl)imide ([N₁₁₁₁][FSI]), yielding solid state electrolytes with notable properties, including high ionic conductivities (1.79 mS·cm^-1 for LiFSI doped and 3.2 mS·cm^-1 NaFSI doped, both at 80 °C), elevated diffusion coefficients (up to 3.83 × 10^-11 m²·s^-1 for Li⁺ at 80 °C), and high transference numbers (
