Abstract

All-solid-state K batteries are ideal energy storage devices for grid-scale applications of renewable energies. A novel electrolyte K[B₃H₇NH₂BH₂NH₂B₃H₇] with weakly coordinating anions was synthesized. It has a high K⁺ conductivity of 1.01 × 10⁻⁴ S cm⁻¹ at 75 °C, which is probably due to the increased electrostatic potential and size of the anions.
