Nickel strips play a critical role in lithium battery packs by serving as conductive pathways between individual cells. These strips ensure that energy flows efficiently from one cell to another, enabling the battery pack to deliver consistent power output.
A standard size, such as 4 mm, is often used to optimize conductivity and minimize overheating risks. Without the correct dimensions, energy loss and thermal issues may compromise your battery pack's reliability. Correct nickel strip size improves battery safety and performance.
The thickness and width of nickel strips are critical for ensuring the efficiency and safety of your battery pack. These dimensions directly influence the strip's ability to carry current without overheating or causing energy loss.
Welding, particularly spot welding, is the most common method for attaching nickel strips in lithium-ion battery packs. It uses high-current pulses to fuse the strip to the battery terminal, creating a strong and durable bond. This technique minimizes heat transfer to the battery cell, reducing the risk of thermal damage.
