The battery that powers electric vehicles is known as a power battery by domestic and international customers in the electric vehicle and new energy vehicle industries. Battery shell is the new energy vehicle’s power battery bearing component, and it is primarily used to protect the lithium battery from external collisions without causing any damage to the extrusion. Aluminum shell and steel shell are the two most common materials for power battery casings; however, aluminum alloy is more commonly used due to its lighter weight. At the same time, the use of aluminum is an essential factor in promoting the lightness of the automobile. Aluminum coil of the 3003 variety is the preferred material for the manufacture of power battery casings.
Aluminum casings for power batteries are typically fabricated from 3003 aluminum sheet in H14 condition, with a thickness of between 0.8 and 3 mm. Width and length can be tailored to meet specific user requirements. 3003 aluminum alloy can be used for deep drawing, stamping parts, models, and shells due to its good formability, good surface, and good pressure resistance. The 3003 aluminum alloy power battery shell has the characteristics of impact resistance, is not prone to cracking and leaking, and meets the requirements for strength and stiffness. The low density and light weight of aluminum alloy can reduce the weight of the battery, increase the battery’s capacity density, stabilize the battery’s operation, and indirectly reduce the vehicle’s weight and increase its range.
The aluminum-manganese alloy series of Yutwin Aluminum includes 3003 aluminum coul. It is also known as rust-proof aluminum sheet due to the manganese alloy component that gives it excellent rust-resistant properties. The strength is approximately 10% greater than that of 1100, and the formability, solubility, and corrosion resistance are all excellent. It is used for processing parts that require good forming properties, high corrosion resistance, good weldability, or both these properties and higher strength than 1XXX series alloys, including kitchenware, food and chemical product handling and storage devices, tanks and jars for transporting liquid products, various pressure vessels and pipes processed in thin sheets, general utensils, heat sinks, make-up plates, photocopier rollers, and ships.
Aluminum alloy of aluminum power battery shell (except shell cover) can be formed in one stretching, compared to stainless steel shell, can eliminate the box bottom welding process, in the case of welding will not appear because of metal elements burned and caused the decline in quality of the weld seam and other problems.
New energy electric vehicles require a large number of lithium battery combination modules. Since each module is comprised of multiple battery boxes, the quality of each battery box has a significant impact on the quality of the entire battery module. To reduce the battery’s quality, aluminum alloy must be used to create the battery shell.
In recent years, the demand for the development of clean energy in China has led to a sudden and rapid increase in the number of electric vehicles. In the production of electric vehicles, the 3003-H14 casing for its core power battery is the primary material.
For the safety and service life of power batteries, it is crucial to select a high-quality shell material and an encapsulation process based on the shell material’s specific characteristics.
The battery case must be formed by repeatedly punching an aluminum plate with good elongation 5-7 times. For the current domestic production of aluminum plate grades, the hardness of 5 series, 6 series, 2 series, and 7 series is too great for deep punching. And the 1 series and 8 series hardness is inexpensive and unsuitable for large capacity batteries, so 3003 alloy aluminum sheet from performance to composition, after many experiments, is very suitable for the shell of new power battery materials.
The 3003-H14 state of the material is better suited for automatic semi-automatic punching systems, resulting in greater production efficiency. Consequently, some domestic corporations with a strong scale strength are now primarily utilizing H14 3003 battery shell material.
3003 aluminum alloy material density is low, it is a soft material, has the advantage of being simple to form and stretch, and has been utilized by numerous companies for battery packaging. Aluminum alloy has a significantly lower density than conventional stainless steel encapsulation materials. The 3003 aluminum plate is simple to process and form, resistant to corrosion at high temperatures, heat transfer and electrically conductive. 3003 aluminum alloy power battery aluminum shell (excluding shell cover) can be formed in a single stretch, eliminating the need for box bottom welding in comparison to stainless steel shells.
3003 aluminum is one of Yutwin Aluminum’s advantageous products; the manufacturer can customize the production to the user’s specifications; the sheet’s thickness ranges from 0.1 to 500 millimeters and its width ranges from 100 to 2650 millimeters; orders of 10 to 5,000 tons are accepted; the sheet’s performance is stable and its processability is excellent, welcome to contact us for inquiry.
