SPECIALTIES OF THE STRUCTURE AND CONDUCTIVITY OF THE NON-AQUEOUS ELECTROLYTES BASED ON ALKALJ METAL bis (SALICYL) BORATES AND bis (OXALATO) BORATES

摘要

The structure and coordination environment of non-aqueous electrolytes based on bis (salicyl) borates of lithium, sodium and potassium, and bis (oxalato) borates from lithium to cesium using NMR spectroscopy have been investigated. The NMR spectra analysis of ~(13)С and ~(11)В found the presence of R-, S-enantiomers in bis (salicyl) borate anion with a labile coordination sphere of boron in the presence of a solvent. This difference affects the final structure of the electrolytes and leads to a change in the thermal dependence of the electrical conductivity of bis (salicyl) borates and the ways of ions transport relatively bis (oxalate) borates in nonaqueous solvents.
