What effect does the specific surface area of lithium ferrous phosphate have on the slurry?
Effect of specific surface area of lithium ferrous phosphate on slurry; Lithium ferrous phosphate has a small particle size and a large specific surface area, which will absorb more NMP solvent during slurry mixing, resulting in a decrease in the solid content of slurry. In the production process of lithium ion battery, the preparation of slurry is the first process, and the technological applicability of slurry after stirring directly affects the subsequent coating and the final battery performance. Compared with other cathode materials, lithium ferrous phosphate has a small particle size and a large specific surface area, which will absorb more NMP solvent during the mixing process of the slurry, resulting in a decrease in the solid content of the slurry. The slurry with low solid content needs to evaporate more NMP during the drying process of coated pole pieces, which leads to the decrease of coating speed and the increase of equipment energy consumption.
