#QTNano: Copper (Cu) electrocatalysts are known as the only single-metal catalysts able to reduce carbon dioxide CO2 further than products such as CO and HCOOH with considerable efficiency. However, the product distribution varies depending on the type of Cu surface employed, and reaction mechanisms for such wide product distributions remain open discussions. Here, we have employed density functional theory (DFT) calculations to study the interaction between Cu surfaces presenting different levels of adsorption site coordination and several intermediates that could be present in CO2 reduction towards CO, HCOOH, CH4 , and CH3 OH. https://lnkd.in/ddVNB2za

Schematic plot of the Borophene-MoS2 hetostructure gas sensor with Gold electrode. Using DFT combined with NEGF, borophene-based sensors can be used to detect and distinguish CO, NO, NO2 and NH3 gas molecules, MoS2 substrate leads to a non-linear behavior on the current-voltage characteristic, and gold electrodes provide charges to borophene and form a potential barrier, which reduces the current values compared to the current of the systems without gold electrodes.

Just published in acs energy letters, we have shown the importance of chemical compatibility between halide and sulphide solid electrolytes while fabricating bilayer all solid state battery. We have also designed a descriptor based on ionococalency of the central metal atom to quantify the reaction kinetics. We have used Sphere Energy solid-state cells for in-situ monitoring of the impedance at high temperatures to monitor the reactivity between two different SEs. Thanks Daniel Alves Dalla Corte for the support . Also Thanks to Physical Electronics and Icon Analytical for supply and support XPS in RISE. We have measured in-situ XPS with heating inside XPS chamber to probe the reactivity between SEs.

This is an excellent summary diagram of the current advancements in electrolyte development. It is also gratifying to see that the polymer single-ion conductor (1.1×10-3 S/cm at 30C) we investigated remains among the top-tier polymer electrolytes. Our findings indicate that there is still room to further push the conductivity of polymer electrolyte systems toward 10-2 S/cm.

Lithium precipitation caused by poor electrolyte infiltration. #batterytechnology #batterymanufacturing #batterymaterials #electrolytes #electrolyteinjecting #cathode #anode #energystorage #energyefficiency #lithiumprecipitation Electrolyte serves as a channel for lithium ion conduction. If the amount of electrolyte is small or fails to fully saturate the electrodes, lithium plating will occur. This issue is relevant to the public account of battery management system (BMS) for power batteries. Principle: When the amount of electrolyte is small, the migration path of lithium ions between the anode and cathode is obstructed, resulting in grained unlithiated areas or lithium precipitation areas. Characteristics: If lithium ions cannot migrate to the anode, grained unlithiated areas will form at that location. If lithium ions migrate to the anode but fail to embed into the anode, lithium precipitation will occur. Improvement: Calculate the amount of electrolyte to be injected based on the porosity of the electrode films, separator, and the density of the electrolyte. The principle of "more rather than less" should be adopted in designing the electrolyte injection amount.

The conductivity of separators and membranes is perhaps the most important parameter for these electrochemical device components. The MacMullin number is a convenient metric showing how much the conductivity is impeded by the tortuous pores in the separator. Have a look at this post to learn more about the MacMullin number and different ways to measure it: https://lnkd.in/eBsZhhWY In addition, this post explains how to perform two- and four-electrode measurements of the through-plane conductivity of separators and membranes: https://lnkd.in/efSpXa7G #lithiumion #battery #separators #membranes #ionic #conductivity #porosity #tortuosity #chargetransport #electrochemistry

Advanced Electrode Materials for Sodium-ion Batteries with Christopher Johnson from Argonne National Laboratory. The improvement in electrode performance properties of layered sodium transition metal oxide cathodes from baseline NaNi1/3Mn1/3Fe1/3O2 (NMF) to advanced materials will be reported. Through a combination of layer stacking P-type perturbations, precise Na/Mn ratios, selected dopings, and intergrowths, a new class of stable high-SOC materials with layered orientation relationships has been produced. These advanced cathodes are slated towards increasing sodium-ion battery energy densities to >160 Wh/kg in pouch cells. https://lnkd.in/ePkyWT8Y #CET4SodiumIon
