Lithium as an Anode in Concentrated Aqueous Lithium Chloride Solutions: a Feasibility Study

摘要

The anodic efficiency of lithium in the Li/LiCl(aq)/AgCl system was measured as a function of electrolyte concentration (at 5.042, 10.05, and 13.82 m) temperature (-15, -25, and -35C) and current density (5 to 35 ma/sq cm). The anodic efficiency increases sharply with increasing concentration. Small increases in the anodic efficiency can be seen with increasing current densities and decreasing temperatures. The voltage of the system is close to the theoretical voltage indicating that only small polarization effects are present. The study has demonstrated that the system would be feasible for the development of a high energy density, low temperature reserve battery. (Author)
