Lithium Battery Safety/Cell-to-Cell Failure Project FY14 Progress Report
Abstract
The Navy Technology Center for Safety and Survivability of the Naval Research Laboratory is investigating lithium-ion battery cell-to-cell failure modes through development of predictive modeling capabilities and experimental measurements. Recent progress in this project has included determination of critical thermophysical properties of commercial 18650 lithium-ion batteries, such as thermal conductivity, heat capacity and density, non-invasive internal temperature monitoring using electrochemical impedance spectroscopy (EIS), novel surrogate cell design mimicking real battery anisotropic thermal properties, and thermal modeling up to the point of cell failure. Model predictions compared well with experimental data, and this report demonstrates significant progress towards understanding and predicting cell-to-cell failure
