Product Introduction
Products Description
Our Prismatic Cell Aluminum Battery Case uses 6063 aluminum alloy as the base material, which has a tensile strength of more than 260MPa and a density of only 2.7g/cm³, ensuring high strength of the shell while achieving extreme lightweight. The products are divided into standard and customized models: the standard model is suitable for mainstream prismatic cell sizes, with an inner wall flatness error of ≤0.05mm, ensuring close fit between the cell and the shell and reducing PACK assembly gaps; the customized model can adjust the size (length 50-300mm, width 30-150mm, height 10-80mm) according to customer needs, and supports processing heat dissipation holes, pole interfaces and other structures on the shell surface to meet personalized application requirements.
In terms of surface treatment, the Lithium Batteries Square Aluminum Shell adopts trivalent chromium passivation + electrophoretic coating process, with a coating thickness of 5-8μm, and the salt spray test can reach more than 1000 hours, which can effectively resist rain and dust erosion and avoid shell oxidation and rust. The bottom reinforcing rib design increases the product's extrusion resistance by 30%, and even in the case of vehicle bumps or slight collisions, it can protect the internal cells from damage. At the same time, all Aluminum Battery Case have passed IP67 waterproof certification and can work stably in the temperature range of -40℃ to 85℃, adapting to complex environments such as outdoor energy storage and electric vehicles.
Product Advantages
Superior Lightweight & Energy Efficiency
Compared with steel shells of the same specification, the Lithium Batteries Square Aluminum Shell reduces weight by over 40%. When applied to electric vehicles, this lightweight advantage can lower the overall vehicle weight, directly increasing the cruising range by 5-8% without changing the battery capacity. For portable energy storage devices, it also makes the end products easier to carry, enhancing user experience.
Cost-Effective Total Ownership
Relying on large-scale production and integrated forming technology, the production cost of our New Energy Aluminum Battery Cases is 15% lower than the industry average. Moreover, the shell's long service life and low maintenance requirements reduce the total cost of ownership for customers by nearly 20% compared to plastic shells that need frequent replacement.
Fast Customization Response
We have a professional R&D team and flexible production lines. For customers' special needs, we can complete the design and sample production of lithium prismatic cells Aluminum shell within 7 days, and realize small-batch delivery in 20 days-far shorter than the 30-day average cycle in the industry-helping customers quickly launch new products and seize market opportunities.
Strong Environmental Compatibility
Our Aluminum Battery Case has a recycling rate of over 95%, and the production process uses water-based environmentally friendly coatings, which reduces carbon emissions by 30% compared to traditional processes. This not only helps customers meet global environmental regulations but also enhances their brand image in the low-carbon market.
Products Workshop
To ensure the quality of Power Battery Cover Plate and production capacity, the workshop layout strictly follows the lean production concept and is divided into four functional areas: material pretreatment area, precision processing area, surface treatment area, and assembly inspection area, realizing the whole process of standardized operations.
The material pretreatment area is equipped with automatic aluminum leveling machines and shears, which can accurately process aluminum alloy coils with a width of 100-1200mm, ensuring the raw material size error is ≤0.1mm; the precision processing area has introduced 20 five-axis CNC machining centers with a positioning accuracy of ±0.005mm, which can efficiently complete the shell milling, drilling, tapping and other processes, with a daily processing capacity of 2,000 sets; the surface treatment area adopts an automatic electrophoretic coating line to realize the fully unmanned operation of passivation, spraying and curing processes, with a coating uniformity error of ≤0.5μm; conducting 100% full inspection on each Battery Aluminum Case to ensure the unqualified rate is controlled below 0.1%.
Professional Certifications
With strict quality control systems and technological innovation capabilities, we have obtained a number of domestic and foreign authoritative certifications, providing strong guarantees for product quality. In terms of domestic certification, we have passed GB/T 19001-2016 quality management system certification, GB/T 24001-2016 environmental management system certification, and GB/T 38052-2020 "Power Battery Shell for Electric Vehicles" standard certification, ensuring that products comply with the relevant regulatory requirements of the domestic new energy industry.
In terms of international certification, the Prismatic Cell Aluminum Battery Case series has passed UL 94 flame retardant certification, IEC 62133 battery safety certification, and environmental certifications such as RoHS 2.0 and REACH. The content of harmful substances is far lower than international limits, and it can be directly exported to European and American markets; the New Energy Aluminum Battery Cases series has also obtained ISO 14064 low-carbon product certification, demonstrating our leading position in the field of green production.
