Lifepo4 Deep Cycle Battery Prismatic Aluminum Shell
Products Description
Lifepo4 Deep Cycle Battery Prismatic Aluminum shells are currently the mainstream packaging solution for power batteries and high-capacity energy storage batteries worldwide.
Physical dimension: Compared to pouch cells, aluminum casings offer extremely high structural rigidity, effectively resisting external compression, punctures, and impacts.
System dimension: Their precise geometry ensures compactness during module-to-pack assembly, which is key to improving volumetric energy density.
Essentially, it is a precision structural component with high thermal conductivity and electromagnetic shielding, protecting the internal chemical system and maintaining its physical stability through thousands of charge-discharge cycles.
Main Functions: Multi-dimensional System Empowerment
Physical Encapsulation and Chemical Isolation
Completely isolates the positive and negative electrode active materials, electrolyte, and external environment (oxygen, moisture) from electrolyte leakage, preventing environmental pollution and preventing harmful external substances from invading the cell and causing side reactions.
Structural Support and Expansion Constraint
Provides tight wrapping force for the core or stacked wafers, maintaining the bonding distance between electrodes and ensuring the stability of the ion transport path; provides continuous mechanical constraint throughout the lifespan, delaying the irreversible increase in cell thickness.
Thermal Conduction Hub
Serving as a thermal bridge between the internal heat source of the cell and the external cooling system (liquid cooling plate, thermally conductive structural adhesive), the thermal resistance of the New Energy Vehicle Aluminum Battery Case directly determines the cell's ultimate heat dissipation capacity.
Electrical Insulation and Safety Grounding
The Prismatic Cell Case itself is a conductor; through external insulating films (such as blue film, PET film), electrical isolation between cells is ensured; at the system level, the aluminum shell also serves as a good grounding path, diverting system leakage current to the ground.
Detailed Display: A Focus on Engineering Quality
Explosion-proof Valve Markings
Under a microscope, uniform V-shaped or U-shaped grooves are visible, without serrations or skewing, and no protruding burrs on the back.
01
Shell Opening Chamfer
Both inner and outer edges have a chamfer of R0.2~R0.5mm to prevent scratches to operators or damage to the cover sealing ring.
02
Inner Wall Cleanliness
Wiping with a white cotton swab reveals no visible oil stains; particulate residue meets the cleanliness requirements for battery cell assembly.
03
Laser Marking Area
A flat marking area is reserved on the outer wall of the Battery Aluminum Housing, supporting QR code traceability; no protrusions or deformation after marking.
04
Bottom Inner Surface
Smooth and free of pits, ensuring uniform stress distribution at the bottom of the battery cell stack, with no localized stress concentration.
05
Design Advantages: Every detail is designed for cell safety
Explosion-proof valve pre-installed
Precise pressure-reducing and explosion-proof positions are pre-installed on the top or side of the housing to ensure directional pressure relief under extreme internal pressure, preventing the risk of explosion for the Aluminum Alloy Prismatic Battery Case.
Optimized radius
The rounded corner radius, determined through multiple simulation experiments, ensures efficient space utilization during module assembly while preventing material thinning and cracking during deep drawing.
Insulation coating compatibility
Extremely smooth outer wall, perfectly compatible with PET/PVC heat shrink tubing or epoxy coating, ensuring insulation safety between individual cells.
