Excellent Electrical ConductivityThe nickel strips here can be welded directly to 18650, NiCd, NiMH and any other rechargeable batteries. Perfect for building or repairing an electric tool battery pack. | SolderingSome users prefer to build lithium battery packs by soldering. To make the soldering point more reliable, please rough the battery ends with sandpaper first, clean the ends then, and apply soldering flux at last. | Resistant to Rusting and CorrosionThe pure nickel strips from us consist of 99.6% nickel or higher, rust will not happen and affect the life of lithium-ion battery pack, as well as the current conduction between the battery cells. | Nickel ElectroplatingNickel electroplating can provide your project with a nickel layer, to serves the dual purpose of providing a bright, attractive finish as well as improved corrosion resistance or durability. |
To make the selected nickel strips work properly while avoiding waste, please check the "acceptable current" in the comparison chart below.
Users can increase the series connections between each parallel group or by stacking more than one layer of pure nickel strips to increase the current rating.
The hardness of pure nickel is controllable in the annealed process. Pure nickel can be very hard or soft, so the hardness cannot be used to distinguish whether strips are pure or not. All the 0.15mm and 0.2mm pure nickel strips from us are softer than 0.1mm.
1. How to distinguish between pure nickel and nickel-plated strips?
The main differences between pure nickel and nickel-plated steel are the ability of corrosion resistance and electrical conductivity. Most users choose the first method, such as placing a scratched nickel sheet in a corrosive liquid. (The element nickel is ferromagnetic at or near room temperature, you can find this basic information on Wikipedia.)
2. For different batteries, the poles' materials would be different. Most of them are made of stainless steel, iron-plated nickel or iron. In terms of the degree of weldability, stainless steel > iron-plated nickel > iron, which means a 0.15 mm pure nickel sheet can be welded to a battery’s pole made of stainless steel easier than a pole made of iron.
3. Lithium-ion cells are made in various sizes, often assembled into packs for portable electrical tools. Most battery packs also include a BMS to prevent over-charge, over-discharge and short-circuit damage. You also need to prepare a specific charger for your lithium-ion battery pack.
