Lithium-metal batteries

Extending both cycling and calendar life


The solvation structure of an electrolyte and the resulting interphase are crucial for lithium-metal battery performance. Now, an electrochemically inert diluent, designed to selectively interact with electrolyte anions, aids in the formation of an inorganic-rich bilayer interphase, thereby improving cyclability and extending calendar life.
