Predicting the performance of batteries having paste additives

Abstract

This paper discusses how models previously developed at the University of Idaho can be used to design high performance batteries containing paste additives. One model characterizes the conductivity of the active material. With this model, the influence of different additives, both conductive and nonconductive, on the capacity of paste containing these additives can be evaluated. The results of this analysis is then used in a second model to characterize the performance of cells. The models are used in the paper to help design and evaluate a battery for a hybrid electric vehicle. This design example illustrates how the, models can be used to investigate unique designs for electric and hybrid electric vehicles.
