Project Description
Storing the highest energy densities in solid state Li batteries requires the use of metallic Li as the anode, but Li metal is very soft, extraordinarily reactive and difficult to use in practical devices. One idea that is being explored to improve the performance is the formation of high Li content alloys. The simple Li-Mg binary system has been studied extensively and has a wide solid solution range, but does not offer the solution to all the practical difficulties. This project will make and test novel eutectic alloys (with Ca, Sr, and or Ba) with the aim of controlling the microstructure/mechanical properties to improve the electrochemical performance. Samples will be examined using optical and scanning electron microscopy, EDX and XRD techniques to establish the as-cast microstructure, to measure the mechanical properties, and the more promising materials will be selected for electrochemical testing in coin cells.
