Cobalt is a popular metal

“Red Cobalt” is an engrossing piece of writing that was penned by Siddharth Kara, an American researcher who was born in India. Cobalt is an essential component in the industrial production of consumer electronics and electric vehicles.

It will be necessary for batteries to become more affordable and capable of traveling greater distances between charges in order to realize the goal of universal adoption of electric vehicles on the scale that is envisioned. As manufacturers of electric vehicles work to bring their pricing closer to those of internal combustion engines, the prices of lithium-ion batteries have continued to plummet.

I have taken this particular passage from the collection of essays titled “Red Cobalt.” The frightening work “The Congo is bleeding so that you can connect” was written by Siddharth Kara, an American researcher of Indian heritage. Kara’s work was published in 2016. The majority of the content of this book is devoted to describing the challenges that are encountered by those who are employed in artisanal mining activities in the Democratic Republic of the Congo (DRC), which is the source of nearly 70 percent of the world’s cobalt production.

The living and working conditions of people in the Democratic Republic of the Congo who are completely devoted to the extraction of cobalt will be the subject of an upcoming piece that we will explore. The purpose of this report, on the other hand, is to investigate the reasons for the significance of this chemical element in the fields of consumer electronics and electric vehicles. The current state of affairs is extremely important, and there is no indication that its significance will decrease in the years to come.

The fact that cobalt is a ferromagnetic metal suggests that it possesses magnetic properties that are comparable to those of iron. This is the first thing that we are interested in learning about this material. In point of fact, if we take a look at the periodic table of elements, we will notice that it is situated between iron and nickel. This indicates that the atomic structure of these elements, and consequently, their chemical properties, are comparable to one another. An atom of cobalt contains only one more proton in its nucleus and also one more electron orbiting around it than an atom of iron. This is because cobalt is so much more abundant than iron.

These elements are connected in a way that extends beyond their atomic structure and the chemical properties they possess. In point of fact, cobalt is frequently discovered in conjunction with nickel, despite the fact that it is an element that is found in lower quantities than nickel (it is estimated that the crust of the earth contains 0.02% nickel, while only 0.001% cobalt is present). It is also very fascinating to note that cobalt and the alloys in which it is employed are extremely resistant to wear and corrosion, even when subjected to extremely high temperatures. This is something that is incredibly remarkable.

In addition, its hardness and tensile strength are extremely comparable to those of iron and nickel, which would make it an excellent candidate for usage in alloys that are utilized in industrial machinery. It is interesting to note that cobalt is also a component of cobalamin, which is the same thing as vitamin B12. Because of this, it is necessary for cobalt to be present in the bodies of all animals, including humans, albeit in trace amounts.

Nevertheless, this is hardly the end of its applications. To the contrary. One of its isotopes, cobalt-60, is a radioactive metal that is used in radiation to treat certain types of cancer. It contains the same amount of protons and electrons as cobalt (27), but it also has one additional neutron in the nucleus than those found in naturally occurring cobalt. The difficulty is that its half-life, which is the amount of time it takes for half of the nuclei in a sample to disintegrate, is slightly more than five years, and after that point, it continues to be extremely radioactive. As a consequence of this, its utilization in medical applications is decreasing in Western countries.

Now, that’s not all. The use of cobalt in the production of electrodes for batteries, which are used to power many of the electronic gadgets that we use on a daily basis, such as our laptops, tablets, and smartphones, is the application that most piques our curiosity. Cobalt has other applications that we have not yet investigated. It has even come to play an important part in the creation of batteries for electric vehicles, which is why the consumer electronics and automotive industries are currently engaged in a fierce competition over it with the purpose of safeguarding their production for the foreseeable future.

In order to construct a substrate, cobalt oxide is utilized. This substrate is then used to deposit small patches of lithium oxide.
If that is the case, what function does this chemical component serve in the production of lithium-ion batteries? In this context, it is utilized to greatly enhance their performance, which in turn makes it feasible to extend the autonomy of our devices, which is something that each and every one of us truly desires. In point of fact, this application of cobalt has only recently started to be exploited on a massive scale over the course of the past decade. Consequently, up until that point, this metal was primarily acquired from those responsible for its extraction, which are not always companies, but rather companies that are dedicated to the manufacturing of alloys for industrial applications.

In light of the fact that we have reached this point, it is worthwhile to proceed one step further and pause for a brief period of time in order to investigate the specific battery ingredient that cobalt constitutes. Locating it is a straightforward process: it is in the positive electrode. In order to construct a matrix or substrate, cobalt oxide is utilized. This matrix or substrate is then used to deposit small patches of lithium oxide. It is feasible to achieve a storage capacity that is nearly three times more than that of lithium-ion batteries that do not make use of cobalt by employing this method. Not only that, but after around 130 charge cycles, its capacity is reduced by only 1.8%, which is not a bad thing at all.
