Furthering Technology for using Lithium Ion Batteries
Abstract
"Approved for Public Release"Lithium ion batteries are well suited for a wide range of applications Because of their high specific energy and high energy density. Recently lithium ion cells which also have high specific power and high power density have been developed. Some types of lithium ion cells especially lithium iron phosphate and lithium titanate can provide high service life of thousands of cycles.The goal of the proposed research is to develop an experimental and modeling program with emphasis on developing electrical equivalent circuit models to support the study of complex and interactive effects of combined mechanical and electrical loading on safety and integrity of lithium-ion cells, modules, and battery packs. In addition, cell comparison methods will be developed to help the Navy select cells for various applications.Many components of an equivalent circuit model are found using multiple Electrochemical Impedance Spectroscopy EIS experiments at multiple temperatures and many states of charge. A cell test procedure including on the order of 100 cycles is still requires to determine a nonlinear impedance component of the model. These procedures will be used to evaluate a number of candidate cells for use by the Navy in pulsed power and reserve power applications. The end result of this work will be to enable the US Navy and other military organizations to select components and to design energy storage systems forpulsed power and reserve applications.
