Our paper in collaboration with the Juchen Guo group (UC Riverside): “Performance Leap of Lithium Metal Batteries in LiPF6 Carbonate Electrolyte by a Phosphorus Pentoxide Acid Scavenger” was published in ACS Applied Materials & Interfaces today. This work is a culmination of excellent performance of lithium metal batteries and deep, mechanistic understanding. We go beyond just showing the long cycle lifetimes achieved by the addition of P2O5 and show the SEI composition, the electrolyte species present, and develop a feasible reaction mechanism to describe the pathway to producing the moieties responsible for the performance enhancement.
