Pouch Cell Aluminum Laminated Film Short Circuit Tester Lithium Battery Testing Equipment

Product Overview

This high-throughput short circuit testing system delivers precision non-destructive electrical inspection for pouch cell lithium-ion battery manufacturing. Engineered specifically for the critical phase following cell top-and-side sealing and prior to electrolyte injection, the equipment performs rapid insulation integrity verification across electrode tabs and the outer aluminum-plastic laminated film. By identifying micro-shorts, burr contacts, and insulation breakdown early in the production line, the system safeguards subsequent formation cycles, prevents costly electrolyte contamination, and optimizes overall manufacturing yield.

Designed for modern pilot lines, quality control stations, and high-volume cell fabrication facilities, this testing apparatus accommodates a wide range of pouch cell form factors. The instrument accurately tests positive tab to negative tab insulation, positive tab to aluminum-plastic film resistance, and negative tab to aluminum-plastic film integrity. Its intuitive operation and rapid cycle time allow seamless integration into high-cadence battery assembly workflows.

Built with industrial-grade mechanical components and a high-stability pneumatic driving system, this equipment ensures repeatable contact pressure and reliable electrical measurements across continuous operating shifts. The unit eliminates operator-induced variance through standardized pneumatic actuation, giving battery manufacturers the confidence to meet rigorous electrochemical safety and quality assurance standards under high-speed manufacturing conditions.

Key Features

• Comprehensive Three-Point Short Circuit Detection: Simultaneously tests insulation resistance between the positive tab, negative tab, and aluminum-laminated composite film to capture internal short circuits, tab alignment defects, and packaging seal punctures before electrolyte filling.
• High-Throughput Operational Speed: Delivers an impressive production throughput exceeding 900 pieces per hour, enabling rapid, non-bottleneck quality screening suitable for automated high-volume lines and fast-paced pilot manufacturing.
• Precision Pneumatic Clamping Mechanism: Operates within a standard pneumatic pressure range of 0.4 to 0.8 MPa, providing consistent, repeatable contact pressure that protects delicate tab surfaces and pouch seals from mechanical deformation during measurement.
• Fully Adjustable Multi-Axis Probe Assembly: Features highly adaptable probe fixtures that can be adjusted quickly across multiple axes to match specific tab spacings, tab widths, and cell thicknesses without requiring specialized tooling.
• Broad Pouch Form Factor Accommodation: Supports pouch cells with body dimensions up to 150 mm by 80 mm by 12 mm and maximum planar dimensions up to 150 mm by 150 mm, offering maximum flexibility for diverse commercial cell designs.
• Safe Low-Voltage Control System: Powered by a standard single-phase 220V AC input converted internally to a 24V DC operating system, ensuring enhanced operator electrical safety, reduced energy consumption, and high signal-to-noise ratio during testing.
• Rugged Benchtop Industrial Construction: Built into a compact 530 mm by 400 mm by 350 mm footprint weighing 30 kg, the rigid metal chassis minimizes vibration and resists wear in continuous manufacturing environments.
• Immediate Pass/Fail Signal Output: Incorporates clear visual and audible status indicators alongside auxiliary electrical output signals, enabling seamless synchronization with downstream sorting bins or automated pick-and-place robotics.
