400 Sets of Nickel Boxes Fabrication for Lithium Battery Production

400 sets of nickel boxes have been successfully delivered after 4 days of intense work.
The boxes have extremely high welding requirements, as it requires high-temperature sintering, the weld seams must be fused through and they are subjected to 300 times high-temperature sintering tests. We used advanced automatic laser welding equipment, and the boxes have passed many tests by the customer and have been well received by them.

nickel box fabrication for Lithium battery production

This batch of nickel boxes is made of pure nickel, which is used in the production line of positive electrode materials for lithium batteries.

Introduction of Pure Nickel

Nickel (Ni) was discovered in 1751 in Stockholm, Sweden by A.F. Cronstedt. It is a silver-white metal which mainly occurs in arsenic and sulfide ores. It is extracted by roasting to NiO and then reducing with carbon. The Mond process is used to manufacture pure nickel, where impure nickel reacts with carbon monoxide (CO) to produce Ni(CO)4, which is decomposed at 200 °C to yield 99.99% Ni. Nickel has an abundance of 80 ppm in the earth's crust.

Pure nickel is resistant to corrosion in water or air,  therefore it is used as a protective coating. It is malleable and ductile and readily soluble in dilute acids but is not affected by alkalis.

When it comes to applications, nickel is used as a constituent of different types of alloys; for instance, Monel (corrosion-resistant material), Nichrome (an alloy used for resistance heating elements), Permalloy (an alloy with high magnetic permeability at low field strength and low hysteresis loss), cupro-nickel, stainless steel, nickel silver, etc.

In addition, nickel is used as a protective coating within the food and chemical handling plants and in coinage.

Nickel is classified as a carcinogen and is also an allergen to certain individuals. However, it is found in many dietary constituents, and hence cannot be avoided easily.

Applications of Nickel

The major use of nickel is in the preparation of alloys. Nickel alloys are characterized by strength, ductility, and resistance to corrosion and heat. About 65 % of the nickel consumed in the Western World is used to make stainless steel, whose composition can vary but is typically iron with around 18% chromium and 8% nickel. 12 % of all the nickel consumed goes into superalloys. The remaining 23% of the consumption is divided between alloy steels, rechargeable batteries, catalysts, and other chemicals, coinage, foundry products, and plating.
Nickel is easy to work with and can be drawn into wire. It resists corrosion even at high temperatures and for this reason, it is used in gas turbines and rocket engines. Monel is an alloy of nickel and copper (e.g. 70% nickel, 30% copper with traces of iron, manganese, and silicon), which is not only hard but can resist corrosion by seawater, so it is ideal for propeller shafts in boats and desalination plants.
