Automatic Vacuum Sealing Machine for EV Battery Cells

USE CASES

Applies multi-stage vacuum compression and sealing for large cells to control swelling risk and internal pressure balance.

Why this machine: Its multi-stage deep-vacuum process is specifically calibrated for thick EV electrodes, achieving a final moisture content of <20ppm. This is critical to pass automotive safety standards and prevent swelling over thousands of cycles.

Ideal User: EV pouch cell manufacturers and automotive battery pilot or production lines.

When to choose: When sealing large-format cells where incomplete degassing can lead to swelling, safety risks, or early pack failure.

Core Advantages vs Conventional Vacuum Sealing Models

Large-format EV battery cells generate significantly higher gas volumes during formation compared to small consumer cells. Deep-vacuum sealing systems are specifically designed to address this challenge through multi-stage degassing strategies and stable pressure control.

By thoroughly removing trapped gases from thick electrodes and high-capacity cells, these systems mitigate swelling risks, improve mechanical stability, and enhance long-term safety. This capability is a decisive factor in ensuring durability and reliability across extended EV duty cycles.
