Customized Prismatic Battery Cell Casings
Products Description
This Customized Prismatic Battery Cell Casings is a customized square aluminum-cased lithium battery shell. Its core function is to provide sealed protection, structural support, and a heat conduction channel for square lithium battery cells, while adapting to the personalized needs of different cell sizes, capacities, and operating environments. The product is integrally molded from high-purity aluminum alloy, possessing core characteristics such as lightweight, high strength, and corrosion resistance. We can provide full-process customization services, from material selection and structural design to manufacturing processes, based on customer engineering drawings, performance parameters, and application scenarios. It is widely used in B2B fields with stringent requirements for lithium battery safety and compatibility, such as energy storage systems, industrial automation equipment, new energy commercial vehicles, and special vehicles.
Compared to general-purpose shells, our customized square aluminum shells focus more on deep matching with customer cell solutions. Through meticulous design and precision manufacturing, we effectively solve the pain points of traditional shells, such as poor compatibility, uneven heat dissipation, and insufficient structural strength, providing core assurance for the stable operation of lithium battery modules.
Design Advantages: Engineering-Driven Perfection for Ultimate Adaptability
Customized Structural Design
We deeply understand customer cell parameters, module assembly methods, and installation space requirements, optimizing shell dimensions, wall thickness distribution, and internal support structures to ensure a perfect fit between the shell and the cell. We also provide precise positioning holes and wiring ports for module assembly, improving assembly efficiency.
Optimized Heat Dissipation Design
Based on cell power and heat dissipation requirements, we employ a reasonable heat dissipation fin layout and heat conduction channel design, combined with the high thermal conductivity of aluminum alloy, to achieve rapid heat dissipation and prevent localized overheating of the cell. For high-temperature applications, we can design additional heat insulation layers or reinforced heat dissipation structures.
Safety Protection Design
Integrates multiple safety designs, including short-circuit protection, overvoltage protection, and impact protection. Rounded corners on the casing prevent sharp edges from damaging battery cells or module components. Sealed interfaces enhance waterproof and dustproof performance while providing pressure release channels to mitigate the risk of battery thermal runaway.
Lightweight Design
While ensuring structural strength, topology optimization, and appropriate material selection minimize casing weight, contributing to lightweight upgrades in end products, particularly suitable for weight-sensitive applications such as new energy vehicles and portable energy storage.
Key Product Functions: Beyond the Container Itself
Physical Protection and Structural Support
As the first line of defense for the battery cell, it resists external impacts, compression, and vibration, protecting the internal core/laminated cells from mechanical damage.
01
Heat Dissipation Channel
The excellent thermal conductivity of aluminum alloy makes it part of the battery's thermal management system. The casing quickly conducts heat from inside the cell to the coolant channels or the external environment, preventing thermal runaway.
02
Chemical Stabilization Container
It provides a sealed space isolated from the outside environment, preventing electrolyte leakage while blocking external moisture and oxygen, maintaining a stable environment for chemical reactions inside the cell.
03
Electrical Insulation (Matching System)
Although aluminum is a conductor, our casing design allows space for insulating coating or the installation of insulating films, ensuring the high-voltage insulation safety of the battery pack.
