Modeling of Lithium-Ion Cell Performance
Agency / Branch:
DOD / MDA
Global Technology Connection, Inc., in collaboration with academic partners, Georgia Tech"s Center for Innovative Battery and Fuel Cell Technologies, Penn State University, and industrial partner Eagle Picher propose to create a physics-based modeling for predicting the life performance of Low and Middle Earth Orbit (LEO/MEO) Lithium-ion cells. The relationships between solid-electrolyte interphase (SEI), electrolyte chemistry, Li+ or other active material loss, temperature, depth of discharge, self-discharge, discharge rate, and capacity fade will be determined through the model. Development of Li-ion performance physics-based models will assume graphite as the negative electrode material. The statistical relationships between aging cells and measurable quantities will also be analyzed through non-parametric models. Methodologies to collect accelerated test data from batteries and to assess the ability to make performance predictions from these data will also be determined. Models created during Phase I will be validated using existing Li-ion battery data sets.
