Prismatic Battery Aluminum Extrusion End Plate with Various Width Custom Height

Prismatic Battery Aluminum Extrusion End Plate with Various Width Custom Height Multi Cell Compatible

Product Overview

Our prismatic battery aluminum end plate is manufactured through a precision aluminum extrusion process, offering exceptional dimensional consistency along the extrusion axis. Available in multiple width options with fully customizable height to suit diverse cell formats and pack designs.

Aluminum Extrusion Process Advantage

• Superior Grain Structure: The extrusion process produces a uniform, elongated grain structure in 6061-T6 or 6063-T5 aluminum, delivering higher strength-to-weight ratio compared to cast alternatives. Ideal for structural end plates that must withstand cell expansion forces during charge-discharge cycling.
• Width Flexibility on One Axis: Extrusion tooling allows multiple width options from a single die family. Standard widths available for common cell formats, with the ability to create custom width profiles for unique pack designs.
• CNC Finish Machining: Cut-to-length from extruded profiles, then CNC machined for precise mounting hole positions, terminal interfaces, and flatness within +/- 0.05mm tolerance.

Key Features

• Various Width Options: Choose from a range of standard widths optimized for popular cell sizes, or supply your drawing for custom width profiles. The extrusion process makes width variation cost-effective without requiring new casting tooling.
• Customizable Height: Height is fully customizable to your specification. Whether you need compact end plates for small-format modules or tall plates for large-capacity stacks, we cut to your exact dimension from extruded profiles.
• Multi-Cell Compatibility: Engineered for 100Ah, 280Ah, 314Ah and other mainstream square aluminum shell LiFePO4 prismatic cells. End plate geometry can be optimized for any prismatic cell format.
• Flexible Terminal Mounting: Available with precision through-hole or tapped hole configurations for terminal installation, matched to your electrical connection requirements.
• Enhanced Thermal Conductivity: The dense, void-free extrusion structure provides superior thermal dissipation, helping manage cell temperature in high-power charge-discharge applications.
