Composição, eletrólito, dispositivo eletroquímico e método para produzir um sal dodecarbonato monovalente

摘要

The disclosure relates to new compositions comprising an, B12FxH12-x- anion that may be prepared chemically or electrochemically by oxidation of B12FxH12-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 fomation at elevated potential can serve to limit the upper limit of voltage during the overcharge of such a cell.
