But while lithium and cobalt deservedly get a lot of the press, there is another metal that will also be changed forever by increasing penetration rates of EVs in the automobile market: nickel. Today’s infographic comes to us from North American Nickel and it dives into nickel’s rapidly increasing role in lithium-ion battery chemistries, as well as interesting developments on the supply end of the spectrum.

Nickel’s Vital Role

Nickel’s role in lithium-ion batteries may still be underappreciated for now, but certainly one person familiar with the situation has been vocal about the metal’s importance. – Elon Musk, Tesla CEO and co-founder Indeed, nickel is the most important metal by mass in the lithium-ion battery cathodes used by EV manufacturers – it makes up about 80% of an NCA cathode, and about one-third of NMC or LMO-NMC cathodes. More importantly, as battery formulations evolve, it’s expected that we’ll use more nickel, not less. According to UBS, in their recent report on tearing down a Chevy Bolt, here is how NMC cathodes are expected to evolve: The end result? In time, nickel will make up 80% of the mass in both NCA and NMC cathodes, used by companies like Tesla and Chevrolet.

Impact on the Nickel Market

Nickel, which is primarily used for the production of stainless steel, is already one of the world’s most important metal markets at over $20 billion in size. For this reason, how much the nickel market is affected by battery demand depends largely on EV penetration. EVs currently constitute about 1% of auto demand – this translates to 70,000 tonnes of nickel demand, about 3% of the total market. However, as EV penetration goes up, nickel demand increases rapidly as well. – Ivan Glasenberg, Glencore CEO

The Supply Kicker

Even though much more nickel will be needed for lithium-ion batteries, there is an interesting wrinkle in that equation: most nickel in the global supply chain is not actually suited for battery production. Today’s nickel supply comes from two very different types of deposits:

Nickel Laterites: Low grade, bulk-tonnage deposits that make up 62.4% of current production. Nickel Sulfides: Higher grade, but rarer deposits that make up 37.5% of current production.

Many laterite deposits are used to produce nickel pig iron and ferronickel, which are cheap inputs to make Chinese stainless steel. Meanwhile, nickel sulfide deposits are used to make nickel metal as well as nickel sulfate. The latter salt, nickel sulfate, is what’s used primarily for electroplating and lithium-ion cathode material, and less than 10% of nickel supply is in sulfate form. Not surprisingly, major mining companies see this as an opportunity. In August 2017, mining giant BHP Billiton announced it would invest $43.2 million to build the world’s biggest nickel sulfate plant in Australia. But even investments like this may not be enough to capture rising demand for nickel sulfate. – Wood Mackenzie on

#1: High Reliability

Nuclear power plants run 24/7 and are the most reliable source of sustainable energy.  Nuclear electricity generation remains steady around the clock throughout the day, week, and year. Meanwhile, daily solar generation peaks in the afternoon when electricity demand is usually lower, and wind generation depends on wind speeds.As the use of variable solar and wind power increases globally, nuclear offers a stable and reliable backbone for a clean electricity grid.

#2: Clean Electricity

Nuclear reactors use fission to generate electricity without any greenhouse gas (GHG) emissions.Consequently, nuclear power is the cleanest energy source on a lifecycle basis, measured in CO2-equivalent emissions per gigawatt-hour (GWh) of electricity produced by a power plant over its lifetime. The lifecycle emissions from a typical nuclear power plant are 273 times lower than coal and 163 times lower than natural gas. Furthermore, nuclear is relatively less resource-intensive, allowing for lower supply chain emissions than wind and solar plants.

#3: Stable Affordability

Although nuclear plants can be expensive to build, they are cost-competitive in the long run. Most nuclear plants have an initial lifetime of around 40 years, after which they can continue operating with approved lifetime extensions. Nuclear plants with lifetime extensions are the cheapest sources of electricity in the United States, and 88 of the country’s 92 reactors have received approvals for 20-year extensions. Additionally, according to the World Nuclear Association, nuclear plants are relatively less susceptible to fuel price volatility than natural gas plants, allowing for stable costs of electricity generation.

#4: Energy Efficiency

Nuclear’s high energy return on investment (EROI) exemplifies its exceptional efficiency. EROI measures how many units of energy are returned for every unit invested in building and running a power plant, over its lifetime. According to a 2018 study by Weissbach et al., nuclear’s EROI is 75 units, making it the most efficient energy source by some distance, with hydropower ranking second at 35 units.

#5: Sustainable Innovation

New, advanced reactor designs are bypassing many of the difficulties faced by traditional nuclear plants, making nuclear power more accessible. 

Small Modular Reactors (SMRs) are much smaller than conventional reactors and are modular—meaning that their components can be transported and assembled in different locations. Microreactors are smaller than SMRs and are designed to provide electricity in remote and small market areas. They can also serve as backup power sources during emergencies. 

These reactor designs offer several advantages, including lower initial capital costs, portability, and increased scalability. 

A Nuclear-Powered Future

Nuclear power is making a remarkable comeback as countries work to achieve climate goals and ultimately, a state of energy utopia. Besides the 423 reactors in operation worldwide, another 56 reactors are under construction, and at least 69 more are planned for construction. Some nations, like Japan, have also reversed their attitudes toward nuclear power, embracing it as a clean and reliable energy source for the future.  CanAlaska is a leading exploration company in the Athabasca Basin, the Earth’s richest uranium depository.
