2019/7/8· Lithium-ion batteries have become ideal energy sources in the 21st century due to their lightweight, small volume, high specific energy, small self-discharge and long cycle life 1,2,3,4.Because
AIN powders were prepared by in-situ synthesis technique. It is a reaction of binary molten Al−Mg alloys with highly pure nitrogen. It was confirmed through thermodynamics calculation that Mg element in Al−Mg alloys can decrease oxygen content in the reacting system. Thus, nitridation reaction can be performed to form AIN. Moreover, an analysis of kinetics shows that the nitridation
