2019 has been declared by UNESCO as the Year of the Periodic Table. To celebrate, we are releasing a series of blogs about our favourite elements and their importance to the chemical industry. Today’s blog focuses on Nickel.
Nickel, a silvery-white lustrous metal with a slight golden tinge may be commonly known as a US five cent coin, however, today nickel is one of the most widely used metals. According to the Nickel Institute, the metal is used in over 300,000 various products. It is also commonly used as a catalyst for hydrogeneration, cathodes for batteries and metal surface treatments.
Nickel in batteries:
Historically, nickel has been widely used in batteries; nickel cadmium (NiCd) and in nickel metal hydride (NiMH) rechargeable batteries. These batteries were used in power tools and early digital cameras. Their success as batteries in portable devices became a stepping stone that led to the significant use of NiMH batteries in car vehicles, such as the Toyota Prius.
The demand for nickel will increase even further as we move away from fossil fuel energy. More energy wll need to be stored in the cathode part of lithium-ion batteries as a result.
Socio-economic data on nickel demonstrates the importance the nickel value chain has on industries, which includes mining through end use to recycling.
The data reflects that globally, the nickel value chain supports a large number of jobs, primarily ones in manufacturing and chemical engineering. The output generated by nickel related industries is approximately €130bn, providing around 750,000 jobs.
Nickel is fully recyclable without its qualities being downgraded, making it very sustainable. It is difficult to destroy and its qualities – corrosion resistance, high-temperature stability, strength, recyclability, and catalytic and electromagnetic properties are enabling qualities required for sustainability.
