Summary: This study investigates the effects of Zr doping on the ionic conductivity and electrochemical stability window of Li3-xEr1-xZrxCl6 halide solid electrolytes. The results show that Zr doping can increase the ionic conductivity but narrows the electrochemical stability window. Furthermore, carbon additives are beneficial for achieving high discharge capacity, better cycling stability, and rate performance in halide-based all-solid-state lithium-ion batteries.

Summary: Currently, there is significant interest in sulfide-based solid electrolytes, particularly the argyrodite-type solid electrolyte Li6PS5X (X = Cl, Br, I), due to its decent mechanical strength and high ionic conductivity (>10-3 S/cm). However, it still lags behind liquid electrolytes in terms of ionic conductivity and is unstable in moist air. In this study, SeS2-doped Li6PS5Cl electrolyte was prepared through high-energy ball milling and heat treatment. The synthesized electrolyte exhibited improved ionic conductivity, stability against Li metal, and electrochemical performance compared to the pristine Li6PS5Cl electrolyte. Furthermore, it demonstrated good air stability properties, making it a promising candidate for solid-state lithium batteries.

Summary: To address the issues of lithium dendrite growth and incompatibility with high cell voltage cathode materials in solid-state batteries, a blending approach of Li3N/Li3YCl6 and Li6PS5Cl (LPSCl) is proposed. The (10 0-x) LPSCl:x(Li3N/Li3YCl6) (x = 0, 2, 5 and 10) solid electrolyte composition is synthesized using ball milling, and phase purity analysis shows that the composition maintains argyrodite structure. Electrochemical impedance measurement reveals that the composition with lower concentrations of Li3N/Li3YCl6 (x = 2 and 5) exhibits an ionic conductivity over 1 mS cm-1. Critical current density measurement demonstrates that the composition of 98LPSCl: 2Li3N has a higher critical current density of 0.55 mA cm-2 compared to other compositions. The assembled battery using 98LPSCl: 2Li3N shows a discharge capacity of 179.1 mAh g-1 with a capacity retention of 92.3% over 100 cycles, and maintains a high reversible capacity of 131 mAh g-1 at 2 C rate. Finally, the use of 95LPSCl:5Li3YCl6 composition as an interlayer between the electrode and the electrolyte interface increases the coulombic efficiency of the solid-state battery to 74.9%.

Summary: Chloride electrolytes have regained attention in recent years due to their stability at high potential. Y-based chlorides, such as Li3YCl6, have a significant ionic conductivity of around 10(-4) S/cm. The crystal structure of solid-state electrolytes (SSE) plays a crucial role in their ionic conductivity. A low lithium concentration composition and cation doping can improve the ion diffusion in the crystal structure. By performing ab initio molecular dynamics (AIMD) simulations, it was found that lithium-deficient state composition and Nb5+ doping can enhance the ion conduction of LiaYClb electrolytes. Experimental synthesis of lithium-deficient state compositions and Nb-doped chlorides resulted in Li2.31Y0.98Nb0.02Cl5.31, which exhibited high ionic conductivity and electrochemical stability in solid sintering preparation. The full cell of Li(2.31)Y(0.9)8Nb(0.02)Cl(5.31) matched with bare LiCoO2 showed stability over 100 cycles.

Summary: This study designs and synthesizes dual-metal Fe/Co-N/S-x-C catalysts with different doping amounts of sulfur and investigates the influence of N/S local coordination on the electrochemical catalytic oxygen reaction. It is found that the doping of S atoms changes the active center structure, resulting in localized strain and electron rearrangement. Furthermore, S atoms modulate the orbital hybridization and accelerate the ORR. Theoretical and experimental results demonstrate the bifunctional electrocatalytic performance of Fe-Co-N/S-2-C, making it promising for zinc-air batteries.

Summary: Modifying sulfur cathodes with Chevrel phase Mo6S8 nanosheets can effectively address the challenging problems in Li-S batteries. Unlike previous inactive hosts, the Mo6S8 reaction is intercalative and can dynamically enhance the adsorbability for LiPSs and ionic conductivity through reversible electrochemical lithiation. As a result, Mo6S8 nanosheets act as a dynamic-phase promoter and exhibit superior cycling stability, high-rate capability, and low-temperature performance in Li-S batteries. This study opens a new avenue for the development of high-performance Li-S batteries with dynamic regulation activity.

Summary: Based on theoretical predictions of the oxygen reduction reaction mechanism, dual-atomic-site catalysts Fe/Mn-N-C were constructed for catalyzing oxygen electrochemiluminescence. Computational simulation showed a synergic dual-site cascade mechanism that overcame the weak adsorption of OH* on single Fe site by introducing Mn as the secondary metallic active site. Fe/Mn-N-C DACs exhibited superior catalytic activity for oxygen reduction, surpassing the performance of single-site catalysts Fe-N-C and Mn-N-C.

Summary: Solid electrolytes are important materials for energy storage and conversion applications, and the coexistence of the paddle-wheel effect and vacancy diffusion mechanism is commonly observed. However, the mechanism contributing to this coexistence remains unknown. In this study, the phase stability and conduction properties of Na3SO4F (NSOF) and magnesium-doped NSOF (Na2.98Mg0.01SO4F, NMSOF) were evaluated. It was found that incorporating Na vacancies in NSOF significantly increased the ionic conductivity, with a 2 order of magnitude difference compared to NSOF. The vacancies also lowered the phase transition temperature, indicating their role in enhancing Na cation mobility.
