Title: Physics Based Modeling Tools for Next-Generation Lithium Ion Battery Performance and Lifetime
Agency / Branch: DOD / MDA
Contract: HQ0147-12-C-7163
Award Amount: $993,559.00
 

Abstract:

The MDA is developing the Precision Tracking Space System and other satellite based systems that could benefit from ongoing developments in advanced materials for lithium ion batteries. Unfortunately, the applications driving much of that battery research have less abusive operational cycles than the frequent cycling, and sporadic pulse loads to deep discharge, of MDA satellite applications. Physics based models of battery performance and degradation for promising material chemistries are desired to help screen candidates that can meet calendar and active life requirements under abusive orbital mission profiles, and to support and improve accelerated life testing for earlier insertion. In Phase I, CFDRC and our partner Washington University in Saint Louis developed and validated fast, predictive electrochemical models to aid in screening next-generation lithium ion batteries for MDA applications. The models included variable lithium diffusivity in the active material particles, improving predictive capabilities for promising materials, and detailed treatment of interfacial film formation that reduces battery capacity and/or rate. During Phase II, we will incorporate additional degradation mechanisms and material property models. Model parameters will be extracted from and validated against laboratory cycling data, then the models will be applied to estimate battery life cycles and analyze/improve testing protocols.
