Following several years of swift progress, China now stands as a major global player in the production and sales of new energy vehicles. With the rollout of the national subsidy policy for new energy vehicles in 2019 and the subsequent rise in range demands, there is an increased focus on enhancing the energy density of battery systems. Enhancing the specific energy of individual battery cells proves to be technically challenging, requiring extended R&D phases and substantial capital investment; in contrast, achieving a lighter weight structure for battery packs is more straightforward. Therefore, the lightweighting of battery pack casings holds significant importance in boosting the energy density of battery packs.

Aluminum alloy boasts a range of advantages including low density, high specific strength, thermal stability, corrosion resistance, and superior thermal conductivity. It is non-magnetic, easily moldable, and possesses a high recycling value. Consequently, aluminum alloy is an ideal material for lightweight design in battery packs.

The battery aluminum tray primarily employs 3-series and 6-series aluminum alloys, with the 6061 grade being the most widely used. The 6061 aluminum alloy plate, an Al-Mg-Si alloy, is characterized by its light weight, low melting point, corrosion resistance, and ease of processing. Its overall strength satisfies the load-bearing requirements for batteries.

OES utilizes the principle of atomic emission spectroscopy to excite the surface of metal materials, producing light of specific wavelengths. By measuring the intensity of this light, the content of various elements in the material can be determined. This method can analyze multiple elements simultaneously and has the advantages of fast speed and high accuracy. Ensure consistency in product quality during production control and avoid quality issues caused by ingredient fluctuations. In addition, by analyzing the waste materials in the production process, the production process can be optimized and costs can be reduced.

Bruker OES is currently widely used in the production of aluminum battery trays by enterprises. Its excellent performance and good service have been recognized and recommended by our customers.
