Summary of Pack Aluminum Housing industry knowledge

With the advancement of the global "double carbon" goal, the new energy vehicle industry has ushered in explosive growth, and the demand for power batteries, which are core components, has also exploded. In the cost structure of new energy vehicles, the battery system accounts for a very high proportion, and the New Energy Vehicle Aluminum Battery Case, as a key structural component of the battery system, undertakes the important functions of protecting the internal cells, dissipating heat, and supporting the overall structure. Compared with traditional steel shells, aluminum alloy shells have become the mainstream choice for current power battery and energy storage battery shells due to their lightweight, high specific strength, excellent corrosion resistance and good thermal and electrical conductivity. In addition, the recyclability of aluminum is also in line with the industry development trends of green manufacturing and the circular economy.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Because aluminum alloy materials are relatively soft, they are prone to scratches during stamping and handling. In order to meet the weather resistance and aesthetic requirements in different application scenarios, surface treatment processes are crucial. Currently, there are four main categories of surface treatment technologies used in the industry:

Powder electrostatic spraying: Use the principle of electrostatic adsorption to attach the powder coating to the surface of the shell and heat to solidify. This process can significantly improve the corrosion resistance of the shell, making its resistance to acid, alkali and salt spray much better than ordinary oxidized profiles, and it has a wide range of color options, such as dark gray, black, military green, etc.

Electrophoretic coating: the directional migration and deposition of pigments and resin particles through an external electric field. The surface of the electrophoresed Aluminum Battery Case has a soft luster, is non-toxic, easy to automatically control, and can effectively resist the erosion of acid rain, cement and mortar.

Plasma-enhanced electrochemical surface ceramization (micro-arc oxidation): This is a technology that uses micro-arc instant high-temperature sintering in a high-pressure area to generate a ceramic film. Compared with traditional anodizing, its film layer is more uniform and dense, and its comprehensive mechanical properties are high. Aluminum Metal Stamping can prepare ceramic film layers with excellent wear resistance, corrosion resistance and decorative properties, but the cost is relatively high.

Sanding process (chemical sanding): In order to solve the pain point of mechanical sandblasting being difficult to achieve uniformity when processing thin walls or small parts, chemical sanding technology came into being. Aluminum Stamping uses chemical reagents to smooth and sand the surface of the workpiece to obtain a delicate and soft damask-like sand surface effect, avoiding light interference from the bright surface and improving the visual texture of the product.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

New Energy Vehicle Aluminum Battery Cases are mainly used in two major areas: power batteries and energy storage batteries. In the field of power batteries, in addition to new energy vehicles, it also covers the light power market such as electric bicycles and power tools; in the field of energy storage, it is widely used in the power generation side (wind and solar storage), grid side, communication base station backup power supply and household energy storage. As the energy storage industry enters the fast lane, the demand for Lithium-ion Battery Aluminum Shell will continue to rise.

From the perspective of the industrial chain, China's power battery and aluminum case manufacturing industries are highly concentrated and have an obvious head effect. Although the domestic market is currently facing intensified competition brought about by production capacity expansion, technological progress and cost control are still the core of corporate competition. As global demand for electric vehicles increases, Europe and the United States are facing battery supply shortages, which provide opportunities for Chinese companies to build factories overseas and export manufacturing capabilities. Future competition will no longer rely solely on Lithium Cell Aluminum Can capacity scale, but will shift to technology iteration and globalization.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The development of new energy vehicles and power batteries has become the consensus of global automotive industry countries. China's industrial chain has established a solid foundation in terms of technology accumulation and scale effect. However, in the face of catching up with Europe, the United States, Japan and South Korea, it is necessary to maintain a sense of urgency in technological iteration and global layout. Aluminum Metal Stamping and Custom Aluminum Stamping are the core processes of battery case manufacturing, and their accuracy and efficiency directly determine the market competitiveness of the product.
