Dodecaborate salt radical anion compositions and methods for making and using such compositions

摘要

The disclosure relates to new compositions comprising an, B₁₂F_xH_12−x⁻ anion that may be prepared chemically or electrochemically by oxidation of B₁₂F_xH_12−x²⁻ salts. This anion can be generated electrochemically in a voltammetry experiment, or by chemically by treatment of the (2−) anions with powerful oxidants such as XeF2 or NO2(+) salts. The new compositions can be used as 1 electron chemical oxidants and in electrochemical cells such as lithium ion batteries where their formation at elevated potential can serve to limit the upper limit of voltage during the overcharge of such a cell.
