I want to prepare wt. 2% Alg as a binder for lithium battery. After stiring for 12h, the droplet will attach on the bottle wall. I think this will cause inhomogenous of binder. In addition, I used this binder to make working slarry, the droplet appear again on the bottle wall after stiring for 12h. Eventually, it's hard to obtain an uniform working electrode fim.
Can you konw how to avoild this condition, or how will this condition affect the working electrode?
That solution doesn't look very viscous for 2%, are you using deionized water alone as solvent? It looks as if the water is evaporating and condensing inside the bottle; what temperatures has it reached during stirring? If that is the case, you can simply swirl it in the capped bottle to recapture the water, and rest it to homogenize. Is that your concern, or is it causing a specific issue with your slurry?
Thanks a lot, Anne Sawhney. The solvent is only deionized water and the concentration is wt 2%. I have check it for several times. The bottle was put on the stirrer under roomtemperature. As your suggestion, I swirled it in the capped bottle to recapture the water and used it to make a slurry, but it will condense inside the bottle again, as shown in Figure 2. I used the slurry to prepare working electrode, however, the films were not always uniform after heat treatment.
