Abstract
Colloidal and processing science characterization techniques provide a valuable approach to the synthesis & processing of battery electrodes. The use of tools such as zeta potential & rheology paired with other spectroscopy techniques allows for a systematic development of slurry-based electrode fabrication. These techniques will be presented as they apply to the understanding and optimization of an aqueous, Si-based anode system. The effect of particle size, surface charge, and the selection of additives and processing aids on the rheological behavior will be discussed. In addition, the use of spectroscopy methods, such as FTIR and RAMAN, to further elucidate the understanding of the Si surface during processing will be considered. This research was conducted at Oak Ridge National Laboratory, managed by UT Battelle, LLC, for the U.S. Department of Energy (DOE) under contract DE-AC05-00OR22725.
