High slurry viscosity creates excess pressure and limits coating speed, elasticity causes instabilities leading to coating defects and high flow causes slumping leading to thin, poorly structured coatings.
Are lithium-ion battery slurries suitable for rechargeable batteries?
Lithium-ion battery slurries are prepared for rechargeable batteries. The dispersion state of slurry constituents is identified. Thermal, morphological, rheological, and electrical properties of slurries are analyzed.
How do slurries affect the performance of lithium-ion secondary batteries?
The chemophysical properties of slurries, which are influenced by the interaction among active materials, conductive additives, and polymer binders in the slurry solvent, play a key role in determining the performance of lithium-ion secondary batteries, .
What are the rheological properties of battery slurries?
Therefore, a comprehensive understanding of the rheological properties of the battery slurry at various scales is necessary to optimize the LIB manufacturing process. LIB slurries are multi-component suspensions exhibiting various complex rheological properties, including yielding, viscoelastic, thixotropic, and shear-thinning behaviors.
Are rheological properties of lithium-ion battery anode slurries important?
This study provides a comprehensive analysis of the complex rheological properties of lithium-ion battery anode slurries, vital for optimizing the battery manufacturing process. The transient behavior of the slurry is significantly influenced by time and shear rate scales, as evidenced through a series of rheological measurements.
Which slurries are used for coating in lithium-ion battery manufacturing?
Slurries used for coating in lithium-ion battery manufacturing are highly non-Newtonian and exhibit shear thinning properties, where the viscosity of the slurry decreases with an increase in shear rate in the narrow gap between the slot-die and the moving substrate or foil.
What is a multi-component slurry for rechargeable batteries?
A multi-component slurry for rechargeable batteries is prepared by dispersing LiCoO 2, conductive additives, and polymeric binders in a solvent. The physical properties, including rheological, morphological, electrical, and spectroscopic features of battery slurries are investigated.
