How to choose a nickel strip for a lithium battery?
The width and material of the nickel strip should be selected according to the current of the lithium battery pack. In terms of material, there are two commonly used nickel strips: pure nickel strips and nickel plated steel. What is the difference between their performance and actual use?
Do nickel strips affect the internal resistance of lithium-ion batteries?
For instance, Li et al. (2017) explored the resistivity of nickel strips and their impact on the internal resistance of lithium-ion battery packs, finding that thinner strips with higher resistivity contributed to increased voltage drop and energy losses.
How effective are nickel strips in a series parallel battery pack?
In a series parallel battery pack configuration, the effectiveness of coated and pure nickel strips is assessed, with particular attention paid to how they influence voltage drop, internal resistance, and overall efficiency. Each of the 24 series and 3 parallel cells that make up the battery pack has an internal resistance of 6 mΩ.
How much resistance does a battery pack have?
Each of the 24 series and 3 parallel cells that make up the battery pack has an internal resistance of 6 mΩ. Two configurations are analyzed: one utilizing pure nickel strips and another with coated nickel strips.
What is a nickel strip in a battery pack?
Nickel strips, which serve as conductors between cells in a battery pack, play a critical role in determining the internal resistance and current distribution across the pack .
How much current can a nickel strip withstand?
For nickel-plated steel, its calculation formula is usually calculated according to 7A/mm², that is to say, the maximum continuous overcurrent of nickel-plated steel with a thickness of 0.15mm*7mm is 7*0.15*7=7.35A. It can be seen that the current that a pure nickel strip can withstand is about 1.5 times that of nickel plated steel.
