Product Details

Hot Press and Formation Equipment for Lithium Pouch Battery

I. Equipment Overview

1. Function (Principle)

This equipment is primarily used for the formation of polymer battery cells under high-temperature and pressure conditions. It helps to form a denser SEI film, enhance capacity utilization, and improve capacity consistency. The system supports large current charging, which shortens formation time and reduces the battery production cycle.

The machine integrates the hot press fixture and formation system into one unit. It consists of a 128-channel formation power supply and one set of fixture.

2. Main Functions

The equipment is composed of six major systems: temperature control, over/under-temperature alarm, over/under-voltage alarm, pressure control, formation cabinet system, and fixture mechanism.

It features: Independent temperature control for each board layer, pressure control, charge/discharge functions, overcharge/discharge protection, reliable contact between battery tabs and contact points, data connectivity, data storage upon process completion, voltage sorting after charging, capacity sorting after discharging, and smoke alarm system.

6. Operating Procedure

Power On → Manually open cabinet door → Insert batteries into fixture A → Set parameters for fixture A → Fixture A presses down and starts process → Remove batteries manually after fixture A finishes...

7. Equipment Features

1. Compatible with cell thicknesses from 2.5–9 mm without needing fixture adjustments or tab block replacement

2. Fixture aluminum plates are 17 mm thick grid-structured lightweight aluminum, offering good strength and no deformation

III. Main Software Functions

1. Working modes include: constant current charging, constant current/constant voltage charging, constant current discharging, resting, and cycling;
Charge/discharge cut-off conditions: voltage, time, end current, and end capacity.

2. Formation steps support power-off resume, manual pause/resume, software shutdown resume, communication interruption resume, and abnormal stop resume.

3. Stores all step curves for each battery. Test data is stored and can be viewed at any time for both current and historical data of each channel.
Data and curve are presented correspondingly in two formats, and support exporting to Excel individually or in batches.
Additionally, automatic data export can be configured upon test completion.

4. Multiple battery inspection interfaces available: graphical display, comprehensive data, categorized data, and error display.

5. Supports protection and alarm functions for all steps, including voltage, current, temperature, and pressure anomalies.
