Abstract : Work continued on this battery on a number of critical areas. The electrolyte/solvent material is very expensive and is typically supplied in small quantities. The requirement for water content is very strict as well as for the presence of any organic impurities. A technique of purifying low cost technical grade electrolyte materials was developed by using zeolites. The water was analyzed by Karl Fisher titration, and the first treatment removed the water content to 50 ppm. A second treatment lowered the water content to below 10 ppm. These purified materials will be tested by using them in button cells.
