As a cornerstone in the initial stages of a sophisticated lithium ion battery production line, our 900*1200 Positive Electrode Roll Pressing and Slitting Integrated Machine exemplifies precision engineering. This machine plays a dual role in preparing the positive electrode material: it precisely presses the electrode to a uniform thickness, crucial for energy density and performance, and then accurately slits it into desired widths for subsequent cell assembly. This integrated approach significantly enhances efficiency and reduces potential defects that can arise from separate processing steps.
This machine is specifically designed for high-volume, high-precision manufacturing environments, ensuring uniform density and precise dimensions of electrode sheets. These characteristics are paramount for the overall performance, safety, and longevity of the final lithium-ion battery.

Our 900*1200 machine is engineered to excel within the high-performance segment of these ranges.
The manufacturing of a lithium-ion battery cell is a complex multi-stage process, demanding extreme precision at every step. The lithium ion battery assembly machine, especially components like our integrated press and slitter, plays a pivotal role in the initial, critical phase of electrode preparation. Here's a simplified overview of a typical lithium battery production line, highlighting key stages:
Active materials (e.g., LiNMC, LiFePO4 for cathodes; graphite for anodes), conductive additives, and binders are precisely mixed with solvents to create a uniform slurry. This step demands accurate weighing and mixing to ensure electrochemical performance.
The prepared slurry is uniformly coated onto a metal current collector foil (e.g., aluminum for cathode, copper for anode). Coating thickness and consistency are critical for battery capacity and safety. Precision coating machines ensure even distribution.
The coated electrodes are dried in high-temperature ovens to evaporate the solvent, leaving a solid active material layer. This process must be carefully controlled to prevent cracking or delamination.
The dried electrode sheets are then passed through high-precision roll presses. Our **900*1200 Positive Electrode Roll Pressing and Slitting Integrated Machine** excels here. This step compacts the active material, increasing its density and improving electrical contact between particles and the current collector. Optimized pressing enhances volumetric energy density and cycle life. The precise gap control, often down to microns, is paramount.
Immediately after pressing, the wide electrode rolls are precisely cut into narrower strips (slitting) to the exact dimensions required for individual battery cells. The integrated slitting function of our machine ensures seamless transition, preventing material damage and maintaining precise width tolerances. This reduces material handling and potential contamination, improving overall line efficiency.
The processed positive and negative electrode strips, along with separator films, are precisely stacked (for pouch/prismatic cells) or wound (for cylindrical cells). Automated stacking/winding machines are highly advanced, ensuring perfect alignment to prevent internal short circuits.
Tabs from the electrodes are welded, and the cell assembly is placed into its casing (pouch, prismatic can, cylindrical can). This requires high-precision laser welding or ultrasonic welding technologies.
The assembled cell is vacuum-filled with electrolyte. This is a critical step, often performed in a dry room environment, as the electrolyte activates the cell's electrochemical reactions.
Cells undergo initial charging/discharging cycles (formation) to form the Solid Electrolyte Interphase (SEI) layer, which is crucial for battery performance and longevity. Degassing removes any gases produced during formation. This is followed by an aging period to stabilize the cell.
Finished cells are rigorously tested for capacity, internal resistance, voltage, and other performance metrics. Automated sorting machines classify cells based on these parameters for consistent battery packs.
Our **900*1200 Positive Electrode Roll Pressing and Slitting Integrated Machine** streamlines steps 4 and 5, providing a foundational layer of precision and quality that propagates throughout the entire battery manufacturing ecosystem. Its contribution directly impacts the yield, efficiency, and ultimate performance of the final lithium-ion battery.
