Lithium Ion Cell Aluminum Case
The Lithium Ion Cell Aluminum Case of a prismatic lithium-ion cell serves not only to encapsulate and mechanically protect internal components—such as electrodes and electrolyte—but also plays a direct role in dimensional control, thermal management, sealing integrity, and subsequent module assembly. Consequently, for power batteries in new energy vehicles, energy storage batteries, and industrial lithium batteries, the aluminum casing is far more than a simple metal container; it is a critical structural component that influences manufacturing consistency and the efficiency of pack integration. Xiamen Apollo specializes in the precision machining of metal structural components for new energy batteries, offering customers prismatic aluminum alloy casings and tailored manufacturing solutions based on specific cell dimensions, structural designs, and assembly requirements.

Product Introduction
Product Definition: A prismatic battery cell casing manufactured from battery-grade aluminum alloy using precision cold-forming processes; it serves as a fundamental component providing airtight protection, structural support, and thermal management for the cell.
Product Features:
Comprehensive Structural Range: Accommodates standard prismatic casings, long/thin casings, and custom-shaped designs; depth, opening configuration, and bottom structure are tailored to the customer's specific cell design.
Flexible Delivery States: Offers various delivery options-such as formed-and-cleaned, surface-treated, or ready-for-production-line-to align with the customer's inbound material handling capabilities.
Key Characteristic Tracking: A "Key Characteristic List" is established during the development phase for every casing model; attributes directly impacting customer processes-such as opening dimensions, wall thickness limits, and end-face conditions-are individually numbered, controlled, and tracked.
Manufacturing Advantage: Transparency Breeds Trust for Polymer Lithium Battery Case
| Production Floor with Full Data Traceability | Process parameters, inspection results, and equipment status are recorded in real-time for every stage, enabling complete traceability of the data chain for any product batch during customer audits. |
| Automation to Mitigate Human Variability | Automated equipment is deployed in critical molding and inspection processes, minimizing the impact of personnel or shift differences on quality. |
| Redundancy in Tooling and Production Lines | Backup molds and alternative production routes are established for critical housing components, ensuring uninterrupted supply to customers even during equipment maintenance-supply chain resilience is a dimension often overlooked by buyers until a crisis occurs. |
| Independent Quality Veto Power | The quality department operates independently of production performance metrics and holds veto power over product release, effectively eliminating the industry-wide issue of rushing shipments through despite quality concerns. |
Application advantages for Lithium Ion Battery Pack: one set of processes covers multiple product lines
Power battery cells
Large number of groups, sensitive to cumulative errors, emphasis on wall thickness uniformity, diagonal control, and batch consistency
01
Energy storage cells (household, industrial, and commercial)

Frequently Asked Questions for Customized Prismatic Battery Cell Casings
Q1: Which cells are suitable for Lithium Ion Cell Aluminum Case?
-
Mainly used in square lithium-ion batteries, including new energy vehicle power batteries, LFP batteries, and industrial and commercial energy storage batteries. The specific size and structure need to be confirmed according to the customer's cell design.
Q2: Can the square lithium battery aluminum case be customized?
-
Can. The length, width, height, wall thickness, fillet, shell opening, interface position,and some functional structures can all be customized according to customer drawings.
Q3: Why is aluminum alloy shell suitable for prismatic lithium batteries?
-
Aluminum alloy has lower density, good thermal conductivity,ty and good formability. At the same time, it can form a rigid shell structure, which is suitable for battery cell designs that require weight, space utilization,tion and mechanical protection.
Q4: Can Apollo develop battery aluminum shells based on 3D drawings?
-
Can. Customers can provide 2D engineering drawings, 3D models,odels or physical samples, and the engineering team evaluates materials,molds and molding processes based on the product structure, and develops samples.
Q5: How to confirm whether the aluminum shell is suitable for my battery project?
-
It is recommended to provide cell size, material requirements, annual demand, case structure diagram, and subsequent welding/packaging method when enquiring; Apollo can conduct a manufacturing feasibility assessment and confirm the specific plan based on this.
