In lithium-ion battery manufacturing, the fineness of the slurry (mainly referring to the electrode slurry) is a key parameter affecting electrode performance (such as capacity, rate capability, cycle life, safety) and process stability. Different battery types have significantly different fineness requirements for the slurry (usually measured by particle size distribution indicators such as D50, ...

I. Characteristics and Advantages of Polyacrylate (PAA) Binders Minimal Swelling in Electrolyte Solvents: Exhibits low swelling, maintaining structural integrity of electrode sheets during charge/discharge cycles. High Proportion of Carboxyl Groups: The high density of polar carboxyl groups forms strong hydrogen bonds with hydroxyl-containing active materials, enhancing dispersion stabil...

Self-discharge in lithium-ion batteries refers to the phenomenon where the battery's charge/voltage naturally decreases when disconnected from an external circuit (i.e., in an open-circuit state). This is an inherent characteristic of all batteries, though the degree varies. Lithium-ion batteries exhibit a relatively low self-discharge rate but are still affected. The primary causes can be categor...
