The Limited Effect of VC in Graphite/NMC Cells

2019/11/30We investigate the effect of VC additive in a graphite/NMC333 (lithium-nickel-manganese-cobalt oxide) cell. The addition of VC improves the rate performance, especially, at moderately high rates. A new three-electrode cell design with Li reference electrode was particularly useful in studying the rate performance of each electrode.

Nickel, zinc and nickel-rich NiZn alloys were formed on platinum by galvanostatic pulse plating from aqueous sulfate baths. The alloys were formed in three steps, first in anomalous deposition by a current pulse, secondly by dissolution and oxidation during the open circuit potential in each cycle and finally by anodic stripping of the fully plated sample.

Minerals

The annual global volume of waste lithium-ion batteries (LIBs) has been increasing over years. Although solvent extraction method seems well developed, the separation factor between cobalt and nickel is still relatively lowmdash;only 72 when applying conventional continuous-countercurrent extraction. In this study, we improved the separation factor of cobalt and nickel by complexation

Effects of Sulfidation and Nitrate on the Reduction of N

Instead, the effect of sulfidation on selectivity between nitrate and NDMA of ZVI is more likely to arise indirectly, through differences in reactivity of nitrate with S-ZVI and uS-ZVI. For the appearance of Fe 2+ ( Figure 5 b, blue markers), k obs increased ∼50-fold with nitrate concentration using uS-ZVI, but there was little effect of nitrate when using S-ZVI (marker fill).

Boudouard reaction

The Boudouard reaction to form carbon dioxide and carbon is exothermic at all temperatures. However, the standard enthalpy of the Boudouard reaction becomes less negative with increasing temperature, as shown to the side.While the formation enthalpy of CO2 is higher than that of CO, the formation entropy is much lower.

Effect of electrode material and supporting electrolyte

2014/5/15In order to determine the most favorable condition for the treatment, the effect of various supporting electrolytes including, sodium chloride, sodium sulfate and sodium nitrate, was scrutinized. E. coli is inactivated by 5 log units for a charge loading of 37.30 F/m 3 for sodium sulfate, 24.87 F/m 3 for sodium nitrate and 12.43 F/m 3 for sodium chloride.

Nails in Copper (II) Chloride

2006/4/21The effect of chloride I already got aquainted with, I've seen that before many times, but the effect of the nitrate really puzzles me. As you see, the highschool text books oversimplify things. Even with seemingly simple things like displacement reactions there is a lot more to tell about this than what the school books suggest.
