Therefore, low flow rates and high screw speeds should be used to improve dispersion for the extrusion of battery slurries. The presented dimensionless correlation allows the estimation of the dispersion degree of conductive material in the slurries directly from the process parameters for the evaluated extruder.
Both effects were summarized using the dimensionless flow number or specific feed load (SFL). It was shown that a high flow number induces a lower degree of dispersion. Therefore, low flow rates and high screw speeds should be used to improve dispersion for the extrusion of battery slurries.
Lithium-ion battery (LIB) slurry, which only referred to cathode slurry at the present paper, includes both active material and inactive materials.
Further, extrusion of battery slurries compared to other mixing techniques has shown promising advantages in terms of flexibility, reducing operating costs, and the ability to process slurries with low solvent content .
Furthermore, three different dispersants which are polyethylene glycol octylphenyl ether (Triton X-100, T-100), polyethylene pyrrolidone (PVP) and carboxymethyl cellulose (CMC) are considered to explore how dispersants disperse particles within LIB slurry.
Hydrostatic pressure change of slurry linked to cathode density/volume resistivity. Hypothesis: It is important to elucidate the effect of the particle dispersion/aggregation state of electrode slurries on resulting electrodes for the development of superior lithium-ion batteries.
