  Battery flexible connection aluminum strip is a core component for power transmission in new energy vehicle batteries, lithium-ion batteries, and power battery modules. It delivers excellent conductivity, lightweight design, and superior flexibility to ensure stable current transfer, absorb vibration impacts, and optimize battery pack performance. Henan Mingtai Aluminum Co, Ltd. (stock code: 601677), a leading aluminum processing enterprise with 26+ years of experience, specializes in producing 1060-O battery flexible connection aluminum strips. These products meet IATF 16949 and ROHS standards, making Mingtai a trusted supplier for global new energy battery manufacturers.
  
  

  1. Core Advantages of Mingtai’s Battery Flexible Connection Aluminum Strip

  Mingtai’s 1060-O aluminum strip is engineered to address key demands of battery connection applications, offering five critical benefits:

  [b]●[/b]Cost-Effective & Resource-Rich: Aluminum is 3-4 times more cost-efficient than copper (aluminum price around 18,840 yuan/ton vs. copper’s 69,690 yuan/ton). With abundant global aluminum reserves (over 10 times that of copper), it significantly reduces battery pack production costs .

  [b]●[/b]Lightweight Design for Extended Range: Aluminum has a density of 2.7g/cm³, only 1/3 of copper’s 8.9g/cm³. Using aluminum strips reduces battery pack weight, lowering vehicle energy consumption and extending new energy vehicle range .

  [b]●[/b]High Conductivity & Efficient Heat Dissipation: 1060 pure aluminum boasts a conductivity of 60% that of copper. With 2 times the conductivity per unit weight vs. copper, it ensures stable high-current transmission. Its specific heat (0.897J/gK) is higher than copper’s, enabling faster heat dissipation in limited battery pack spaces .

  [b]●[/b]Superior Flexibility & Vibration Resistance: The O-temper aluminum strip features excellent flexibility and a cupping value ≥7.5mm, absorbing vibrations during vehicle operation to prevent fastener loosening. It supports complex bending and integrated assembly, adapting to compact battery module layouts .

  [b]●[/b]Corrosion Resistance & Longevity: Aluminum forms a dense oxide film on its surface, preventing internal material oxidation. This ensures consistent conductivity and structural integrity, even in harsh operating environments, with a service life of over 10 years .
