4680 Cylindrical Battery Detachable Split Test Kit

Product Overview

This detachable split test kit is designed for laboratory handling and testing workflows involving 4680 cylindrical battery cells. Its separated upper and lower end-cap structure provides a practical enclosure format around the cell, while the internal cylindrical component establishes a defined holding space. The configuration supports repeatable cell positioning during research, evaluation, and related assembly procedures.

The kit is suitable for battery R&D laboratories, cell development teams, university research groups, and advanced materials facilities working with cylindrical cell formats. It can be integrated into physical testing setups where controlled cell retention, electrolyte-resistant sealing, and access to the cell are important. The detachable design also supports inspection, cleaning, configuration changes, and repeated experimental use.

Construction details are selected for demanding laboratory conditions. The end caps use 304 stainless steel, the standard cylindrical body uses PTFE, and the O-ring uses fluoro rubber for resistance to electrolyte corrosion. A spring inside the top cover helps maintain fastening pressure on the cell, while M4 fixing screws provide a defined mechanical connection between the kit components.

Key Features

• 4680 Cylindrical Cell Compatibility: The internal cylindrical space is dimensioned for the specified 4680 battery format, with an inner diameter of 46 mm and an internal height of 80 mm. This geometry gives users a clearly defined cell-holding area for laboratory workflows.

• Detachable Split Construction: The separated upper and lower end caps make the fixture practical to open, remove, inspect, and reassemble. This design is useful when researchers need access to the cell between test stages or want to change experimental configurations efficiently.

• 304 Stainless Steel End Caps: The upper and lower covers are manufactured from 304 stainless steel and have an outside diameter of 68 mm. This material provides a robust structural interface for repeated laboratory handling and fastening operations.

• Electrolyte-Resistant Sealing: The O-ring is made from fluoro rubber, selected for resistance to electrolyte corrosion. The sealing element helps support a more controlled interface around the enclosed cell during battery research procedures.

• PTFE Cylindrical Component: The standard middle cylindrical component uses PTFE, providing a chemically resistant material for the cell-holding section. A PEEK version can be customized when the application requires a different material configuration.

• Spring-Assisted Cell Retention: A spring is built into the top cover to help secure the cell inside the fixture. This integrated fastening feature supports consistent positioning without requiring a separate external retention component.

• Defined Mechanical Fixing: M4 fixing screws connect the assembly components using a specified thread size. The standardized screw specification simplifies identification and helps maintain a repeatable assembly procedure.

• Compact Laboratory Envelope: The assembled external dimensions are Φ68 mm × H106 mm. The compact cylindrical envelope is suitable for test benches and laboratory setups where fixture dimensions must be managed carefully.

• Configuration Flexibility: The detachable structure and optional PEEK cylindrical material allow the equipment to be adapted to different research requirements. Customization can be discussed when the standard PTFE configuration does not match the intended test environment.

Applications

Technical Specifications

The specification set is centered on the physical interfaces that determine compatibility and practical use. The 46 mm inner diameter and 80 mm cylindrical height define the internal holding area, while the 55 mm outer diameter and 80 mm component height describe the middle cylindrical section itself. The 68 mm end-cap diameter and Φ68 mm × H106 mm overall envelope provide the external dimensional references required for fixture planning.

Material selection is equally important when the equipment is used in battery research. The 304 stainless steel upper and lower covers provide the primary structural components. PTFE is used for the standard middle section, and PEEK is available as a customization option. The fluoro rubber O-ring is specified for electrolyte-corrosion resistance, making the sealing material a key consideration when selecting the kit for electrolyte-related workflows.

The top-cover spring is integrated into the fastening arrangement and is intended to help secure the cell. M4 screws provide the defined fixing interface for assembly. Together, these details give laboratory users a clear basis for reviewing mechanical compatibility before integrating the unit into a test platform.

Why Choose This Product

• Purpose-Built Format: The dimensions are defined around 4680 cylindrical battery cell research, giving procurement and engineering teams a clear compatibility reference before equipment integration.

• Robust Material Combination: 304 stainless steel end caps, a PTFE cylindrical section, and a fluoro rubber O-ring address structural handling, chemical resistance, and sealing considerations within one compact fixture.

• Efficient Reconfiguration: The detachable split construction supports cell access, inspection, cleaning, and repeated assembly during development work, reducing unnecessary disruption between experimental stages.

• Practical Retention Design: The built-in top-cover spring and M4 fixing screws provide a specified mechanical fastening arrangement for consistent cell positioning during laboratory setup.

• Customization Potential: The standard PTFE cylindrical component can be customized to PEEK when application requirements call for an alternative material configuration. Contact KINTEK for a quotation or a customized solution matched to your battery research workflow.
