Effect of Ink Composition on the Physical Characteristics and Performance of Aerosol Jet Printed Lithium Cobalt Oxide Cathodes
Abstract
Nine ink compositions were formulated and printed utilizing aerosol jet printing to form lithium cobalt oxide battery cathodes. This fabrication method is being investigated to determine the viability and potential benefit of aerosol jet printing for unique parts where a flat dense cathode would be undesirable. The conditions for creating the ink and printing of the tapes were held constant. The inks and resulting cathode tapes were characterized utilizing TGA, SEM, and electrochemical testing to observe the effect of ink composition on the surface roughness and electrochemical properties of the cathode tapes. The printed tapes had unique surface features that seemed to be ink dependent. This resulted in less dense tapes than the tape cast cathodes. Many of the tapes had a higher specific capacity when compared to similar tape cast materials. These results show this to be a viable fabrication method for lithium cobalt oxide cathodes and further investigation would be encouraged.
