The LiAl/FeS cell batteries currently under development at the Korea Advanced Institute of Science and Technology (KAIST), Seoul, Korea, are unique in that the cell design is cylindrical with the central LiAl negative electrode and surrounding annual FeS positive electrode, isolated with a MgO powder separator containing LiCl-KCl electrolyte. The design of the cells requires less number of components than those of the prismatic design, thus making it simple to assemble. It has been recognized, however, that the P/E ratio of a cylindrical cell in general tends to be lower than that of a prismatic cell for a given cell capacity because of relatively heavy thickness of both anode and cathode. To achieve a high P/E ratio, electrode area must be extended while reducing the electrode thickness. The formation of the reduced electrode thickness, particularly that of the positive is difficult by the common pressing technique. Therefore, new process was developed to form a layer of the positive mixture containing FeS and electrolyte as thin as 1 mm, thus greatly improving the P/E ratio of the cells.
