Strength of Mingtai Aluminum Plate for Lithium Battery Shell

  • 1 We strictly control the production process and provide standardized products

    Battery shell material refers to high-purity aluminum alloy products formed through processes such as hot rolling, cold rolling, annealing, stretching, straightening, and aluminum foil rolling. The production process strictly follows industry-standard regulations. Currently, the company has passed the "ISO9001:2008" quality management system certification and established a strict quality standard system to ensure excellent product performance.

  • 2 The product has a low defect rate and excellent performance. The thickness of the battery shell material product is 0.40-0.60mm, with the advantages of a low defect rate, good deep drawing performance, welding performance, etc. Adding a small amount of manganese to the alloy makes the product strong, corrosion-resistant, high-temperature resistant, and radiation-resistant, and has fast heat dissipation, fully meeting the requirements of cell phone battery case covers.;
  • 3 With a high reputation, it is a supplier for international companies such as Samsung and LG. In the field of cell phone battery shell materials, the company has long-term cooperation with many international companies, including domestic large-scale lithium-ion battery aluminum shell production companies such as Shenzhen Tongli High-tech Co., Ltd. and Shenzhen Youbang Tongbao Industrial Co., Ltd. At the same time, the company is also a supplier of battery accessory products for enterprises such as Samsung Group and LG Group
  • 4 Comprehensive R&D capabilities, ranging from materials to products. We are engaged in total R&D, from basic aluminum technology to products and utilization technologies;

Q & A

  • Q:Is it better to use an aluminum shell or a plastic shell for the lithium battery shell?;
  • A:The aluminum and plastic cases of lithium batteries have their own advantages and disadvantages, which cannot be simply judged. It depends on the use situation and the judgment standard.

    The energy density of the aluminum shell battery is higher than that of the plastic shell, and the aluminum shell itself needs to be insulated because it is a metal shell;

    The plastic case itself has insulating properties, and the handling of the end cap pole is simple, and it is also more convenient to pack, but its energy density is lower than that of the aluminum case.
