The industrial recycling of lithium-ion batteries (LIBs) is based on pyrometallurgical and hydrometallurgical methods.a, In pyrometallurgical recycling, whole LIBs or black mass are first smelted to produce metal alloys and slag, which are subsequently refined by hydrometallurgical methods to produce met...
1 mole of any element contains the same number of atoms as 1 mole of any other element. The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. Themolar massof an element (or compound) is the mass in grams ...
The enzymatic reaction was stopped by adding a 1:1 volume of 0.5 M Na2CO3 (pH 10.5). The absorbance of free 4-NP was measured at 405 nm, and enzyme activity was calculated for each sample (µM × min−1 × mg−1). In addition to the 4-NP-linked substrates, ...
In calcium alginate process, CaCl2 is added to the sodium alginate solution to form insoluble calcium alginate, which is converted into insoluble alginic acid by the addition of dilute mineral acid (e.g., HCl). Alginic acid is finally converted to sodium alginate by the addition of Na2CO3 or...
The effects of NaOH concentration, leaching time, temperature, Na molar ratio of NaOH and Na2CO3 and liquid to solid mass ratio on vanadium removal, and physical chemical properties of leachate were investigated. The optimum conditions were 10 g of petroleum coke, 20 mL of oxidation, 6:1 ...
Sodium carbonate (Na2CO3) was produced as a transition phase between sodium silicate and carbon matrix due to high temperature. According to differential charge density a significant charge accumulation found between the interfacial of Na2CO3 and carbon layer is helpful to polarization. The synergistic ...
