Dispersion hydrophobic electrolyte enables lithium-oxygen battery enduring saturated water vapor

Yinan Zhang et al.

Summary: The introduction of hexamethyldisilazane (HMDS) into the electrolyte of aprotic Li-O-2 batteries has shown to eliminate water-related parasitic reactions, increase discharge capacity, and improve cyclability. The hydrophobic HMDS forms a dispersion electrolyte that captures water on the cathode side, triggering a solution-based pathway and enhancing discharge performance.
