Eberhart, J

Eberhart (1979) has found that the wetting behavior of a battery electrolyte can have a dramatic effect on the internal resistance of the battery as well as its cycle life. Good wetting of battery separators by electrolyte is essential for the easy passage of ions through the separator pores, while porous, gas diffusion electrodes require a lesser degree of wetting. For several years, a room temperature molten salt system has been under study. This system is composed of 1-methyl-3-ethylimidazolium chloride (C6N2H11Cl or MeEtImCl) plus aluminum chloride. The application of this novel liquid solution as a battery electrolyte appears to be promising. Available data suggest that likely candidates include cells with a chlorine positive electrode reactant and a magnesium, aluminum, or zinc negative electrode material. The present investigation is concerned with an assessment of the wetting behavior in the considered system, taking into account a study of the contact angles of various room temperature molten salts on candidate battery separator and porous electrode materials. 10 references.
