DURIP QUANTIFYING LI-ION BATTERY SAFETY AND THERMAL CHARACTERISTICS USING ACCELERATING RATE CALORIMETRY
Abstract
The Department of Defense (DoD) is currently pursuing a range of systems that could leverage the unique capabilities of batteries. However, battery safety is the most critical challenge limiting the integration of batteries into DoD platforms. While the impact ofmaterials, design, and operational and thermal conditions on the electrochemical performance of batteries has increased significantly in recent years, the impact on battery safety remains relatively unknown. This is primarily because of the hazardous conditions that accompany evaluating battery safety and the need for specifically designed equipment and facilities.This equipment acquisition proposal aims to acquire an accelerating rate calorimeter (ARC) system to enable us to quantify the safety and thermal characteristics of Li-ion batteries during normal and abusive conditions. The ARC system#which would establish a first-of-its-kind battery safety testing capability at Iowa State University (ISU)#includes a standard and extended volume calorimeter, gas sampling unit, pressure and temperature sensing, and thermal, mechanical, and electrical abuse capabilities. The ARC will be used by numerous investigators, postdocs, and graduate and undergraduate students on DoD projects to make new fundamental battery safety science discoveries, integrated with existing battery facilities and equipment, and bring new research-related education opportunities to ISU. The probability and severity of battery failure will be realized through quantifiable metrics of interest, such as the onset and severity of thermalrunaway, cell self-heating and heat release characteristics, and the collection and subsequent identification of hazardous gas emissions.The entirely new research capabilities for quantifying battery safety and thermal characteristics at ISU made possible by thisproject will have a long-ranging impact on ongoing and future DoD-supported projects; research-related education at ISU, including our ability to educate/train future scientists and engineers in DoD relevant disciplines; and projects in areas of interest to the DoD.
