Abstract
In this study, trimethylsilyl azide (C3H9N3Si, hereafter denoted as TSA) is used as an efficient electrolyte additive in Li-metal batteries. Along with a LiF-rich compound, the addition of 0.1 M TSA to fluoroethylene carbonate (FEC)-based electrolytes not only induces the formation of a conductive solid-electrolyte interphase layer on the Li-metal surface but also allows the formation of a dense Li-deposit morphology; hence, it greatly enhances the Li plating-stripping reaction kinetics. Upon using the 0.1 M TSA additive, a practical Li/full concentration gradient Li[Ni0.73Co0.10Mn0.15Al0.02]O-2 (FCG73) battery exhibits outstanding long-term cycling stability over 300 cycles and fast charge-discharge capability at a practical level.
