Abstract

Abstract : Lithium metal anodes are challenged by the inherent chemical and electrochemical reactivity of lithium metal, which is further exacerbated by non-uniform high surface area deposition. Recently, lithium difluoro(oxalato)borate (LiDFOB) salt coupled with a fluorinated solvent has been demonstrated to result in densely deposited lithium morphology along with high Coulombic efficiencies due to a stable solidelectrolyte-interphase. Along with other newly discovered electrolyte compositions for stable lithium deposition, these studies typically utilize high stack pressures and elevated temperatures. These developments are promising, and would further benefit from a study that maps out the effects of varying stack pressure and temperature on lithium anode mechanics, chemistry, and electrochemistry.
