Solid state thermal method for the synthesis of lithium hexafluoro phosphate (LiPF)6 as battery electrolyte

   
   

The present invention provides a method for the preparation of LiPF.sub.6 (lithium hexafluoro phosphate) wherein equimolar quantities of pure dry AR lithium source such as Li.sub.2 O or Li.sub.2 CO.sub.3 or LiNO.sub.3 is mixed with (very pure dry and AR samples) diammonium hydrogen phosphate in solid state.

A invenção atual fornece um método para a preparação de LiPF.sub.6 (phosphate do hexafluoro do lítio) wherein as quantidades equimolar da fonte seca pura do lítio de AR tais como Li.sub.2 O ou Li.sub.2 CO.sub.3 ou LiNO.sub.3 são misturadas com (muito puro seque e amostra de AR) o phosphate do hidrogênio do diammonium no estado contínuo.
