Novel ALD Chemistry Enabled Low-Temperature Synthesis of Lithium Fluoride Coatings for Durable Lithium Anodes
The team developed an atomic layer deposition (ALD) method to deposit lithium fluoride (LiF) films on lithium metal anodes. These LiF films enable a stable Coulombic efficiency as high as 99.5% for over 170 cycles, about 4 times longer than that of bare lithium anodes. Read More

ZnNixMnxCo2–2xO4 Spinel as a High-Capacity Cathode Material for Nonaqueous Zn-Ion Batteries
A new series of spinels, ZnNixMnxCo2-2xO4, are reported as a high-voltage and high-capacity cathode material for non-aqueous Zn-ion batteries. Mn, Ni co-substitution for Co in ZnCo2O4 is demonstrated to be an efficient method to facilitate Zn-deintercalation and enhance discharge capacity, which provides guidelines for designing more attractive multivalent cathodes materials.

Tailored Reaction Route by Micropore Confinement for Li-S Batteries under Lean Electrolyte Conditions
Li2S2 is experimentally verified by ex-situ S K‐edge X‐ray absorption spectroscopy to be stable in the micropores during discharging in Li-S cells. A new reversible electrochemical pathway is thus proposed, based on the inherent self‐healing capacity for Li2S2, under lean electrolyte conditions. Read More

Reaction Pathways for Solvent Decomposition on Magnesium Anodes
Dimethoxyethane (DME) is predicted to rapidly decompose to ethylene gas and other products on the metallic Mg surface, whereas the presence of an oxide or chloride surface film on a Mg anode is predicted to limit solvent decomposition. Read More

Substituted Thiadiazoles as Energy-rich Anolytes for Nonaqueous Redox Flow Cells
2,1,3-benzothiadiazole (BzNSN) base molecules were derivatized with various electronic groups to achieve the optimal properties as the anolytes in nonaqueous redox flow batteries. It has been observed that the half-life times of those molecules are nicely correlated with redox potentials. Higher redox potentials lead to long life time or calendar life. The relationship of the molecular stability and the corresponding cycling performance was also investigated. Read More
