Horizontal Hot Press Formation Machine for Pouch Lithium Ion Batteries

Product Overview

This horizontal hot press formation system is engineered for the formation process of single-tab pouch lithium-ion batteries. It applies controlled heat through aluminum plate clamping while pneumatic cylinders hold the cell in compression, supporting rapid heat transfer during activation. By combining heating and pressure in one controlled process, the equipment helps stabilize battery performance, increase physical strength, reduce cell thickness, and produce a firmer finished cell structure.

The equipment is intended for polymer lithium battery manufacturing, particularly production lines handling pouch cells after initial cell assembly. It supports a process in which a suitable low current is applied to activate internal active materials at the electrode terminals. Heat and pressure also promote the melting of binder coated on the separator, helping the separator bond closely with positive and negative electrode materials.

Built around a horizontal configuration, this unit provides 32 operating points in one fixture group and supports a maximum charge-discharge current of 6A. Its controlled temperature, pressure, and pneumatic operating conditions provide a repeatable platform for demanding pouch-cell formation work, while the integrated process can remove the separate baking and shaping step used in conventional formation workflows.

Key Features

• Horizontal Heat-Press Formation Design: The equipment uses a horizontal layout specifically for single-tab pouch lithium-ion battery formation. This arrangement provides a dedicated processing platform for cells placed and clamped between heated pressure plates.

• Integrated Heating and Compression: Heated aluminum plates clamp the cell during formation, combining thermal input with mechanical pressure in the same operation. The process supports fast heat conduction to the cell while maintaining compression through the formation cycle.

• 32-Point Processing Capacity: This system provides 32 points in a single fixture group. The multi-point configuration supports organized handling of multiple cells within one equipment platform.

• 6A Maximum Charge-Discharge Current: The equipment supports a maximum charge-discharge current of 6A. This capability serves the low-current activation process used to activate the internal active materials of newly formed batteries.

• Controlled Temperature Performance: The operating temperature range extends from room temperature to 90 degrees C, with a temperature accuracy of plus or minus 3 degrees C. Initial heating to a target temperature of 80 degrees C is specified at 30 minutes or less.

• Silicone Heating Plate Method: Silicone heating plates provide the heating method for the system. The arrangement works with the aluminum clamping plates to transfer heat rapidly to the cell during formation.

• Pneumatic Clamping Mechanism: Cylinders provide the clamping action between the pressure plates. The specified working air pressure range is 5.0 to 7.0 kgf/cm2, equivalent to 0.5 to 0.7 MPa, using dried, filtered, and pressure-stabilized compressed air.

• High Pressure Operating Range: The pressure range is 300 to 1800 kg, with pressure accuracy of plus or minus 20 kg. This range supports controlled compression for pouch cells with thicknesses from 4 to 12 mm.

• Process Consolidation: Hot press formation can eliminate the baking and shaping operation in an existing battery formation process. This shortens formation time and the overall battery manufacturing cycle while reducing manual work.

• Cell Flatness and Structural Improvement: The combined thermal and pressure process helps the separator and electrode materials form close contact. After degassing and sealing, the resulting pouch battery can be flatter, with increased hardness, improved physical strength, and reduced thickness.

Applications

Technical Specifications

The specified cell envelope is designed for pouch lithium-ion batteries that require controlled hot press formation after initial assembly. Before procurement, buyers should compare their actual pouch dimensions, tab arrangement, current requirements, utility supply, and compressed-air preparation against the stated requirements. This is particularly important where cells approach the maximum 150 mm length, 100 mm width, 12 mm thickness, or 25 mm tab-width limits.

The thermal specification should also be matched to the required formation recipe. The unit operates from room temperature to 90 degrees C and reaches the stated 80 degrees C target in 30 minutes or less during initial heating. The temperature accuracy of plus or minus 3 degrees C and pressure accuracy of plus or minus 20 kg define the stated operating-control performance, while the 300 to 1800 kg pressure range gives the process a substantial compression window for applicable pouch cells.

Installation planning should account for the approximately 1650 x 700 x 1800 mm equipment footprint and approximately 500 kg machine weight. Electrical infrastructure must support the stated AC220V/380V and 50Hz/60Hz supply options. Pneumatic infrastructure must provide dried, filtered, pressure-stabilized air within the stated 5.0 to 7.0 kgf/cm2 range. The rated power is approximately 5 kW, excluding the power cabinet, and final power requirements should be confirmed against the actual supplied equipment.
