Abstract
The present application provides a method for producing an ion conductor containing Li2B12H12 and LiBH4, which includes obtaining a mixture by mixing LiBH4 and B10H14 at a molar ratio LiBH4/B10H14 of from 2.1 to 4.3; and subjecting the mixture to a heat treatment.
Claims11
A method for producing an ion conductor comprising Li2B12H12 and LiBH4, which comprises:
- obtaining a mixture by mixing LiBH4 and B10H14 at a molar ratio LiBH4/B10H14 of from 2.1 to 4.3;
- and
- subjecting the mixture to a heat treatment.
An ion conductor comprising L12B12H12 and LiBH4, which has peaks at at least −15.6 ppm (±1 ppm), −17.6 ppm (±1 ppm), −1.7 ppm and −29.4 ppm (±1.5 ppm), and −42.0 ppm (±2 ppm) in a B11MAS NMR measurement, wherein when −15.6 ppm (±1 ppm) is regarded as Peak A and −42.0 ppm (±2 ppm) is regarded as Peak B, the intensity ratio of Peak B to Peak A (B/A) is 0.1 to 2.0.
