| Abstract Scope |
Safety is critical in moving towards high energy density Lithium-ion batteries (LIBs). Incorporation of material solutions including better electrolyte additives and separators, have limited scope in response time and operating voltage window. Here, we report using internal resistance temperature detector (RTD) for sensing thermal signatures from LIBs with graphite anode and LiCoO2 cathode. The RTD is placed behind anode in 3D printed polymeric substrate with no interfere to cell performance. During short-circuit, temperature recorded with internal RTD was ~6°C higher than with external RTD, along with up to 10-times earlier detection ability to prevent thermal runaway. Additionally, internal RTD is expected to yield more endothermic peaks beyond 200 °C in multimode calorimetry due to the presence of 3D-printed polymer. Results from electrochemical impedance spectroscopy of customized LIBs were comparable to conventional LIBs. Using superior battery management system, the customized LIB will be conducive, safer powerhouse for high energy density applications. |
