Abstract

The alkali metals were electrodeposited from various solutions in propylene carbonate (PC). Li, Na, K, Rb and Cs were electrodeposited from solutions of their chlorides and AlCl3 in propylene carbonate (PC) at ambient temperature. In addition, lithium was deposited from LiCl, LiBr, LiClO4, LiPF6, and LiBF4 solutions in PC. Sodium was reduced from NaClO4, NaPF6, and NaBF4 solutions. Potassium was obtained from KPF6 solution.

A new process is proposed for the production and electrorefining of the alkali metals at ambient temperature. Alkali metal amalgam from the commercial mercury-chlorine cell is transferred into an AlCl3-PC electrorefining cell, where the alkali metal is dissolved anodically from the amalgam, and deposited in a pure form at the cathode.
