Abstract

The conductivity and chemical stability with lithium of various electrolytes containing propylene carbonate (PC) and acetonitrile (AN) were determined. Addition of AN improved the conductivity of LiClO4/PC and LiAsF6/PC electrolytes, and the LiAsF6/PC-AN electrolyte showed remarkable chemical stability in contact with lithium. The lithium cycling efficiency was determined on nickel and aluminium substrates in the various electrolytes over a range of current density. While the efficiencies observed on nickel substrates were very poor for all AN-containing electrolytes, efficiencies approaching those for electrolytes containing only PC were obtained with the LiAsF6/PC-AN electrolyte at low current densities (∼1 mA cm−2) on aluminium substrates. It was concluded that the LiAsF6/PC-AN electrolyte had generally favourable characteristics and may prove suitable for primary battery applications.
