I. Analysis of Dry Electrode Preparation Technology 1. Introduction to Dry vs. Wet Processes and Material Comparison The traditional wet process involves mixing active material, conductive agent, and binder in a solvent at specific ratios, then coating the mixture onto the current collector surface via a slot-die coater followed by calendering. The dry process involves dry-mixing active particles ...read more

Reasons for Self-Discharge in Lithium-Ion BatteriesJul 15 , 2025Self-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...read more

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 stability. Conti...read more

Fineness Requirements for Lithium-Ion Battery SlurryJun 16 , 2025In 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, ...read more

In lithium battery manufacturing, the often-overlooked A/B-side coating misalignment issue during the coating process significantly affects battery capacity, safety, and cycle life. Misalignment refers to inconsistencies in the positional alignment or thickness distribution of coatings on the front and back sides of electrodes, which can lead to risks such as localized lithium plating and mechanic...read more

Non-destructive Methods to Detect Lithium PlatingMay 22 , 2025Lithium plating refers to the detrimental phenomenon where lithium ions fail to intercalate into the graphite anode during charging processes, instead undergoing electrochemical reduction to form metallic lithium deposits. This results in the formation of characteristic silver-gray lithium metal layers or dendritic lithium crystals on the anode surface. Conventionally, battery disassembly has been...read more

Lithium-Ion Battery Capacity Degradation MechanismsMay 09 , 2025A lithium-ion battery is primarily composed of a cathode, anode, electrolyte, and separator. During charging, lithium ions de-intercalate from the cathode material, migrate through the electrolyte, and intercalate into the anode material. During discharging, lithium ions move in the reverse direction, de-intercalating from the anode and returning to the cathode through the electrolyte. This repeat...read more

The voltage of a lithium battery is closely related to the electrode potentials of its cathode and anode materials. Variations in voltage among lithium batteries using different materials primarily stem from the following factors: Impact of Electrode Materials’ Chemical Properties Lithium batteries operate through the movement of lithium ions between the cathode and anode during charging and disch...read more

Analysis of Causes for Low Cells CapacityApr 15 , 2025Low cell capacity is an intuitive judgment based on comparing the post-formation discharge capacity with the design value. If the measured capacity falls below the design specification, the first step is to verify whether the formation process parameters are correctly set (e.g., discharge current, charge duration, cutoff voltage, and formation temperature). ① If the formation steps are confirmed c...read more
