Nickel is commonly used as a lithium ionBattery Tab<\/a>Nickel is often used in battery packs because it has a sufficient combination of conductivity, weldability, strength, plasticity, and corrosion resistance. But as the number of individual cells in a battery pack increases, one problem with nickel is heat generation (especially on the busbars), which reduces the efficiency of the battery and poses a risk of overheating.<\/p>

Nickel's limited thermal and electrical conductivity leads to some unfavorable consequences. First, high amperes contribute to Joule heating on the busbars and cause the battery temperature to rise, which is detrimental to the performance and life of the battery.<\/p>

The performance and life of the battery are compromised. Second, the impedance of the connector material is higher, resulting in more IR drop, so the voltage in the battery is significantly reduced. Third, hot spots will occur due to insufficient thermal conductivity and poor thermal diffusion. Cladding metal connectors have electrical and thermal conductivity advantages to solve these problems and will be characterized below.<\/p>
