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...
