At the heart of these batteries lies the slurry —a critical mixture of active materials, conductive additives, and binders that directly impacts battery performance, cycle life, and safety.
As modern energy storage needs become more demanding, the manufacturing of lithium-ion batteries (LIBs) represents a sizable area of growth of the technology.
Battery materials are the components that make up a battery, each serving a specific role in storing and harnessing electrical energy. The most well-known components are the electrodes (cathode and anode). The materials used

Compared to other rechargeable batteries, lithium batteries are lightweight, have long cycle lives, and have high energy-to-weight ratios . Electrode slurries are dispersions that are typically composed of conductive additives, polymer binders, and electrochemically active material particles that serve as reservoirs for lithium.
The rheological behavior of lithium-ion battery slurries composed of LiFePO 4 and graphite with two polyvinylidene fluoride (PVDF) binders, HSV900 and KF1100, was investigated using steady-state, transient shear flow, creep, and dynamic oscillatory shear experiments.
Electrode slurries are dispersions that are typically composed of conductive additives, polymer binders, and electrochemically active material particles that serve as reservoirs for lithium. They are coated onto conductive substrates and dried to form porous electrodes.
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.
Reducing the amount of liquid solvent in the slurry can increase the concentration of active material, which is beneficial for improving the battery’s performance. However, reducing solvents also increases the viscosity of the slurry, which may require adjustments in the mixing process to prevent clumping or incomplete dispersion.
Three component quantities were varied: active material (graphite), conductive material (carbon black), and polymer binder (carboxymethyl cellulose, CMC). The slurries demonstrated shear-thinning behavior, and suspension properties stabilized after a relatively short mixing duration.
