Computer-Aided Engineering of Batteries (CAEBAT) _ Microstructure Simulation for Virtual Electrode Design
Computer-aided engineering offers a proven pathway to shorten the design cycle and reduce the cost of electric-drive vehicle batteries. DOE's Computer-Aided Engineering of Batteries (CAEBAT) program has greatly enhanced software toolsets available to the battery and automotive industries for battery cell and pack design. Today's battery software tools, however cannot yet predict the behavior of new electrode designs without first building and experimentally characterizing prototype electrodes. The experiment-driven design process is time consuming, expensive, and results in sub-optimal battery designs. Microstructural models of electrodes in theory have capability to predict performance without a prototype. However to date, there is no validated tool that can build realistic microstructure geometry that accounts for stochastic variation in particle morphology; variation in amounts of inert binder and conductive additive; and calendaring process. Funded by DOE Office of Vehicle Technologies, the goal of this project is to create and validate software that may serve as a virtual design tool for battery electrodes.
