Lithiated metallic molybdenum disulfide nanosheets for high-performance lithium-sulfur batteries

Zhuangnan Li et al.

Summary: This study presents the use of pre-lithiated metallic 1T phase two-dimensional molybdenum disulfide (LixMoS2) as a sulfur host material for high-performance lithium-sulfur batteries.

An encapsulating lithium-polysulfide electrolyte for lithium-sulfur batteries

Li-Peng Hou et al.

Summary: This study proposes an encapsulating LiPS electrolyte (EPSE) to suppress parasitic reactions between lithium metal anodes and soluble LiPS based on a nano-heterogeneous solvation structure design. The addition of reduction-stable DIPS in the outer solvent shell significantly inhibits the parasitic reactions between encapsulated LiPS and lithium metal. Experimental results show that a lithium-sulfur battery with EPSE can undergo 103 cycles under demanding conditions.

Surface Film Formation from Sodium Polysulfide Decomposition on Sodium-Metal Anode Surface

Sirisak Singsen et al.

Summary: This study investigates the adsorption behavior of sodium polysulfides on the sodium metal surface and reveals the mechanism of soluble sodium polysulfides decomposition and formation of sodium sulfide film in the presence of different electrolyte solvents. It is found that sodium polysulfide molecules strongly interact with the sodium metal surface via Na-S bonds, leading to the formation of an amorphous sodium sulfide film through spontaneous electron-transfer decomposition of sodium polysulfides.

Insights on the work function of the current collector surface in anode-free lithium metal batteries

Jinkwan Jung et al.

Summary: This study explores the role of the work function of metallic current collectors in anode-free lithium metal batteries (LMBs). It was found that higher index surface facets lead to lower work functions and higher surface energies. A lower work function favors binding with lithium, but it also leads to electrolyte decomposition and the formation of a thick solid electrolyte interphase layer. Increasing the work function can reduce the irreversible capacity and capacity fade rate of anode-free LMBs.
