Solid Interfaces in Lithium Ion Batteries

Abstract

It is difficult to imagine modern life without batteries: they are present in our mobile phones, laptop computers, automotive vehicles, and even more vital devices, such as pacemakers. Most of these gadgets are powered by lithium (Li) ion batteries, in part due to their high voltage window and relative longevity. While this technology has had major successes, at the current rate of progress, it is unlikely to meet the mid-century global demands related to full de-carbonization and interruption of use of fossil fuels for transportation and energy generation. The replacement of currently used anodes by Li metal is one of the most promising puzzle pieces involved in the solution to this problem. However, a myriad of obstacles hinders its commercialization, many of which are related to phenomena happening at the interface between the anode and the electrolyte.
