Abstract
Solid-state lithium sulfur batteries constantly suffer from a poor interfacial compatibility between solid-state cathode/anode and electrolyte, and low critical current density of Li metal anode (< 3 mA cm−2). Here, a concept of a liquid cathode/anode based, room-temperature, solid-state lithium sulfur battery with low impedance electrode/electrolyte interfaces is presented. Due to an extremely stable liquid-solid interface with a high compatibility and unique properties of liquid alloy, the liquid Li-amalgam anode based symmetric cells show a superior electrochemical performance, and no internal short circuit occurs as they run at 55.6 mA cm−2 for 10,000 cycles. Liquid Li2S8 polysulfide catholyte can afford a high active material loading (≥135.2 mg mL−1) and has a good contact with the solid-sate electrolyte. The cathode/anode and electrolyte are tightly welded together by the liquid-solid interfaces, and the resulting cells show high performance and good structural stability during cycling.
