Potassium Difluorophosphate as an Electrolyte Additive for Potassium-Ion Batteries [PDF]

ACS Applied Materials & Interfaces, 2020
The limited cyclability and inferior Coulombic efficiency of graphite negative electrodes have been major impediments to their practical utilization in potassium-ion batteries (PIBs). Herein, for the first time, potassium difluorophosphate (KDFP) electrolyte additive is demonstrated as a viable solution to these bottlenecks by facilitating the ...
