Nonfluorinated Antisolvents for Ultrastable Potassium-Ion Batteries
ACS Nano, 2023A robust interface between the electrode and electrolyte is essential for the long-term cyclability of potassium-ion batteries (PIBs). An effective strategy for achieving this objective is to enhance the formation of an anion-derived, robust, and stable solid-electrolyte interphase (SEI) via electrolyte structure engineering.
