Temperature, Ageing and Thermal Management of Lithium-Ion Batteries

Heat generation and therefore thermal transport plays a critical role in ensuring performance, ageing safety for lithium-ion batteries (LIB). Increased battery temperature is the most important accelerator. Understanding managing operation thus multiscale challenge, ranging from micro/nanoscale within single material layers to large, integrated LIB packs. This paper includes an extended literature survey of experimental studies on commercial cells investigating capacity performance degradation LIB. It compares behavior terms influence operating conditions different chemistries cell sizes. A simple model linking some these parameters together presented as well. While appears have large impact acceleration above room during cycling all studied cells, effect SOC C rate appear be rather dependent.Through application new simulations, it shown that testing, actual can deviate severely reported depending management testing rate. shown, lifetime reduction at high rates parts due increase especially energy poor cooling studies. Measuring reporting (surface) allow proper interpretation results transferring laboratory experiments real applications.
