While the battery cell, BMS, busbar and enclosure receive most of the attention, the cell holder is an important mechanical component inside the battery pack. For prismatic lithium cells, a properly designed cell holder can help maintain accurate cell positioning, controlled spacing, electrical insulation, mechanical stability and repeatable assembly. At Aasic Plastic, we manufacture customized prismatic cell holders for lithium battery pack manufacturers, including solutions developed around large-format LFP/prismatic cells. What Is a Prismatic Cell Holder? A prismatic cell holder is a precision-moulded plastic component designed to position and support rectangular lithium battery cells inside a battery module or pack. Instead of allowing individual cells to move freely inside the enclosure, the holder creates a defined arrangement for the cells. This becomes particularly valuable when multiple prismatic cells are assembled together. The holder can be designed according to: Cell dimensions Cell-to-cell spacing Number of cells Pack configuration Busbar arrangement Terminal location Cooling requirements Enclosure dimensions Compression/support requirements Customer-specific battery pack design Cell positioning and spacing can influence mechanical stability, insulation distances, busbar installation and cooling arrangements. Why Do Battery Pack Manufacturers Use Prismatic Cell Holders? 1. Accurate Cell Alignment One of the biggest advantages of a cell holder is repeatable cell positioning. During battery pack assembly, even small variations in cell position can make the installation of: Busbars Interconnects Insulation sheets Sensors Wiring Compression structures more difficult. A properly designed holder provides a defined position for every cell. This allows the production team to maintain a consistent battery module layout from one pack to another. Result: Better alignment → easier assembly → better production consistency 2. Maintains Consistent Cell-to-Cell Spacing Spacing between prismatic cells is an important mechanical and thermal design consideration. A cell holder can maintain a predetermined gap between cells instead of relying entirely on manual positioning. The required gap should always be determined according to the cell manufacturer's specifications and the battery pack's thermal/mechanical design. Research on prismatic battery thermal management also shows that inter-cell spacing affects cooling behaviour and module energy density. Therefore, the holder should not simply be designed to "keep the cells apart"; it should be designed around the complete battery pack architecture. 3. Provides Electrical Insulation Prismatic cells contain conductive metal surfaces and terminals. A suitable plastic holder can provide an additional electrical isolation barrier between cells and nearby structural components. This can help reduce the possibility of unintended contact during assembly and operation. However, the holder should be considered one part of the insulation system, not the only safety measure. The complete pack still requires appropriate insulation, clearances, creepage distances, busbar protection and electrical design. The material, wall thickness and geometry must be selected according to the actual electrical and environmental requirements of the battery pack. 4. Improves Mechanical Stability Battery packs used in EVs, industrial equipment and energy-storage systems can experience: Vibration Shock Transportation loads Thermal expansion Repeated charging and discharging cycles If cells are not adequately restrained, unwanted movement can place stress on the cell, terminals, busbars and interconnections. A properly engineered holder helps maintain the intended position of the cells and provides a repeatable mechanical interface within the module. This is particularly important for battery manufacturers who need consistent pack construction across production batches. 5. Makes Battery Pack Assembly Easier Imagine assembling 16, 24 or 32 prismatic cells manually without a positioning system. The operator has to repeatedly measure and maintain: Cell position → cell gap → alignment → terminal position → busbar position A properly designed cell holder reduces this dependence on manual positioning. The cells can be placed into predetermined locations, creating a more repeatable assembly process. This can help manufacturers: Reduce assembly time Reduce positioning errors Improve production consistency Simplify operator training Improve repeatability during mass production 6. Supports Better Pack Design A custom cell holder can be designed around the actual battery pack rather than forcing the pack designer to adapt to a standard holder. For example, a manufacturer may require: 100Ah LFP cells + specific spacing + specific busbar arrangement + specific enclosure dimensions The holder can be developed around these requirements. This is particularly useful for: Custom EV battery packs Solar energy storage ESS systems UPS batteries Industrial battery packs OEM battery systems Prototype battery modules 7. Helps Create Modular Battery Pack Structures Custom prismatic holders can be developed with interlocking or modular features, depending on the pack design. For example: 1 + 1 + 1 + 1 or 2 + 2 + 2 + 2 or larger cell arrangements. This allows battery manufacturers to create different module sizes without completely redesigning the mechanical structure for every project. The exact configuration depends on the cell dimensions, pack architecture and customer requirements. 8. Can Improve Production Repeatability For a battery manufacturer, consistency is extremely important. The objective is not simply to manufacture one good battery pack. The objective is to manufacture: Pack 1 = Pack 2 = Pack 3 = Pack 1000 with the same intended cell positioning and assembly geometry. A precision cell holder creates a repeatable mechanical reference for the cells. This becomes increasingly valuable as a battery manufacturer moves from: Prototype → Pilot Production → Mass Production 9. Useful for EV, ESS, Solar and UPS Applications Prismatic cell holders can be useful across several battery applications. Electric Vehicle Battery Packs Suitable for various EV battery module designs where mechanical positioning and insulation are required. Solar Energy Storage Useful for organizing multiple high-capacity LFP cells inside energy-storage systems. UPS & Inverter Batteries Helps maintain organized cell arrangements inside stationary battery systems. Industrial Energy Storage Suitable for larger battery modules requiring repeatable mechanical construction. Custom OEM Battery Packs Particularly useful when the customer requires a cell holder designed around a specific cell and enclosure. Why Custom Prismatic Cell Holders Are Better Than a Generic Holder Not every prismatic lithium cell has exactly the same dimensions. Even cells marketed with the same nominal capacity can differ in: Length Width Height Terminal location Terminal size Case geometry Required spacing For example, a 100Ah LFP cell from one manufacturer may not have exactly the same mechanical dimensions as another manufacturer's 100Ah cell. Therefore, battery pack manufacturers should not select a holder only by the cell's capacity rating. The holder should be matched to the actual cell dimensions and pack design. Aasic Plastic – Prismatic Cell Holder Manufacturing At Aasic Plastic, we manufacture customized plastic components for lithium battery applications, including prismatic cell holders. Our approach is not simply: "Tell us the cell capacity and we will supply a holder." Instead, we can work from the customer's cell dimensions, drawings, samples and pack requirements to develop the required holder geometry. Our prismatic cell holder development can consider: Cell dimensions → Cell spacing → Holder geometry → Interlocking → Assembly → Pack configuration For example, we have developed solutions for large-format prismatic cells such as 160 × 50 mm / 100Ah class cells, including Great Power-type applications. What Information Should You Send Us for a Custom Cell Holder? If you are a battery pack manufacturer and require a new cell holder, you can send us: 1. Cell Dimensions Length × Width × Height 2. Cell Brand & Model For example: EVE Great Power Highstar Ganfeng CATL Other OEM/custom cell 3. Cell Capacity For example: 50Ah / 100Ah / 105Ah / 280Ah 4. Number of Cells For example: 8S / 12S / 16S / 24S / 32S 5. Cell Arrangement Example: 1 × 4 2 × 4 4 × 4 or your custom arrangement. 6. Required Cell Gap If already defined by your battery design, provide the required spacing. 7. Busbar / Terminal Arrangement This helps us understand how the holder needs to accommodate the electrical interconnection. 8. Drawing or Existing Sample A CAD drawing, photograph, physical sample or even a dimensional sketch can be useful for development. From Cell Dimensions to Production-Ready Holder Our development process can be structured as: Customer Cell Data ↓ Engineering Review ↓ Holder Concept ↓ 3D/CAD Development ↓ Prototype / Tool Development ↓ Sample Approval ↓ Production ↓ Bulk Supply This approach allows battery manufacturers to develop a component specifically for their pack rather than compromising the pack design around an unsuitable standard holder. Important: A Cell Holder Is Not the Entire Battery Safety System A cell holder is an important mechanical component, but it should not be considered a replacement for proper battery engineering. Battery safety depends on the complete system, including: Cell quality BMS Electrical protection Busbars/interconnects Insulation Thermal management Mechanical compression Enclosure Fusing/protection Welding/interconnection quality Manufacturing process Testing and validation The holder should therefore be designed as part of the complete battery-pack architecture.
