Description
Lithium-ion batteries used in smart phones last several years. However, they must last at least a decade in electric vehicles and many decades in electrical energy storage systems. In this lecture I will explain why Li-ion batteries eventually fail and introduce simple methods we have invented to rank lithium-ion cell lifetime in experiments that only take a few weeks. These simple methods are crucial for researchers, battery manufacturers and users who cannot test new battery chemistries for years and years to identify better batteries.
