Applied battery and electrochemical research program report for fiscal year 1980
The Exploratory Battery R and D area provides for the study of new electrochemical couples, or of new approaches to known battery systems. High temperature systems under investigation include Ca/molten salt/FeS/sub 2/, Li/LiI-Al/sub 2/O/sub 3//TiS/sub 2/, and Na/..beta..''-Al/sub 2/O/sub 3//SCl/sub 4/-NaCl-AlCl/sub 3/. Ambient temperature systems being studied are Li/So/sub 2//C and Zn/NaOH/Fe(CN)/sub 6/. New electrode/electrolyte formulations for Zn/KOH/NiOOH and Li/organic electrolyte/TiS/sub 2/ cells are being investigated, and a status study of ambient temperature secondary lithium batteries was conducted. Projects grouped in the Engineering-Science Research area include morphological and optical studies of battery electrodes in Pb/H/sub 2/SO/sub 4//PbO/sub 2/, Zn/KOH/NiOOH, and metal/air cells; and a thermal management study of the high-temperature Li/molten salt/FeS Battery. Improvements in alkaline (Zn/NiOOH and Fe/NiOOH) battery performance are being sought. Materials Research seeks to identify, characterize, and improve the materials and components to be used in batteries and electrochemical processes. Basic investigations have led to the discovery of a novel all-solid electrode structure for possible use as negative electrodes in molten-salt cells. New ternary lithium-transition metal oxides have been identified as possible electrode reactants for use in similar systems. Projects aimed at developing improved separators for high-temperature Na/S and Li/S cells are focusing on such materials as ..beta..''-alumina, NASICON, conducting glasses, and novel superionic conductors. New polymeric separators are being studied for use in ambient-temperature Li/TiS/sub 2/ cells, and composition profiles in molten-salt electrolytes are being analyzed. Brief summaries of the separate research projects are presented. (WHK)
