Cobalt’s presence in the cathodes of lithium-ion batteries has been instrumental in enhancing the efficiency, energy density, and overall performance of electric car batteries. However, this reliance on cobalt has raised questions regarding the sustainability and ethical sourcing of this critical element. With a substantial portion of global cobalt production originating from regions associated with social and environmental challenges, the pursuit of a more ethical and environmentally friendly electric vehicle ecosystem becomes paramount.
Join us on a journey into the heart of electric mobility as we explore the multifaceted relationship between cobalt and electric cars. From its role in advancing battery technology to the growing efforts to reduce or eliminate its use, this exploration will illuminate the complexities surrounding cobalt’s necessity in the electrification of transportation and the ongoing quest for a more sustainable and responsible future.
Do all electric vehicles use cobalt?
Currently, several EV manufacturers like Tesla are making batteries without cobalt. These batteries are called iron-phosphate, and they don’t use nickel or cobalt and are often cheaper to produce. However, they are less energy dense, which means they are not as efficient for long-range electric vehicles.
Not all electric vehicles (EVs) use cobalt in their batteries, as the composition of batteries can vary. However, a significant number of EVs rely on lithium-ion batteries that typically contain cobalt in their cathodes. Cobalt enhances the energy density and stability of the battery, contributing to overall performance. Yet, the industry is actively exploring alternative chemistries and formulations that either minimize or eliminate the use of cobalt to address ethical and environmental concerns associated with its mining.

How much cobalt is needed for an electric car?
A typical EV battery has about 8 kilograms of lithium, 14 kilograms of cobalt, and 20 kilograms of manganese, although this can often be much more depending on the battery size – a Tesla Model S’ battery, for example, contains around 62.6 kg (138 pounds) of lithium.
The amount of cobalt needed for an electric car depends on the battery’s specific chemistry and capacity. On average, a mid-sized electric car might contain several kilograms of cobalt in its battery.
What can replace cobalt in EV batteries?
One such material is lithium-iron-phosphate (LFP), which some car manufacturers are beginning to use in electric vehicles. Although still practically useful, LFP has only about half the energy density of cobalt and nickel batteries.
Researchers and manufacturers are actively exploring alternatives to cobalt in electric vehicle batteries to address concerns related to its supply chain, environmental impact, and ethical sourcing. Nickel is a prominent contender for cobalt replacement, and various nickel-rich cathodes are being developed to enhance energy density and reduce reliance on cobalt. Additionally, battery chemistries like lithium iron phosphate (LFP) and solid-state batteries are gaining attention, as they do not contain cobalt and offer promising alternatives. These innovations signal a transformative shift in the industry, aiming to create more sustainable and environmentally friendly electric vehicles.
Why is cobalt bad in batteries?
Environmental Impact: A significant portion of the world’s cobalt supply is mined in regions with lax environmental regulations, leading to habitat destruction and pollution. Cobalt mining is associated with adverse ecological impacts, including soil and water contamination.
While cobalt has been crucial for enhancing the performance of lithium-ion batteries in electric vehicles, its use comes with ethical and environmental challenges. The majority of global cobalt production occurs in the Democratic Republic of Congo, where concerns about child labor, unsafe working conditions, and environmental damage are prevalent.
The mining and extraction of cobalt have raised ethical questions about the human rights and environmental impact associated with its production. Additionally, the geopolitical and supply chain risks linked to cobalt sourcing have prompted the industry to seek alternatives or reduce cobalt content in batteries. Efforts are underway to develop battery technologies that minimize or eliminate the need for cobalt, reflecting a broader commitment to creating more sustainable and responsibly sourced electric vehicles.
Is cobalt costly?
Is cobalt more expensive than nickel? It is priced at about US $ 28,500 per tonne, which is more expensive than the sum of nickel, manganese and aluminum, and accounts for 10-30% of most lithium-ion battery cathodes. “Cobalt is the least contained and most expensive component of the battery cathode.
Cobalt is indeed a relatively expensive metal, and its cost has been a significant factor influencing the economics of lithium-ion batteries, which are commonly used in electric vehicles. The price of cobalt is subject to market forces, including supply and demand dynamics, geopolitical factors, and fluctuations in mining and production. Additionally, the limited geographical distribution of cobalt deposits, with a substantial portion coming from the Democratic Republic of Congo, adds to the complexity of its supply chain, influencing its market price.
Why is cobalt free?
Next-generation batteries could go organic, cobalt-free for long-lasting power. Swapping out cobalt for an organic compound in lithium-ion battery cathodes could help speed the global conversion to electric vehicles. In the switch to “greener” energy sources, the demand for rechargeable lithium-ion batteries is surging.
The term “cobalt-free” in the context of batteries typically refers to efforts within the industry to reduce or eliminate the use of cobalt in battery formulations. Researchers and manufacturers are actively exploring alternative battery chemistries that use less cobalt or substitute it with other materials, such as nickel or manganese.
Can we run out of cobalt?
This tells us how many years of production they could meet with their current reserves. One point to make clear: the world will not run out of cobalt. The world has about 46 years’ worth of known reserves.
The potential for running out of cobalt is a concern, especially considering the growing demand for electric vehicles and energy storage systems that rely on lithium-ion batteries. Geopolitical uncertainties, ethical concerns related to mining practices, and the potential for supply chain disruptions all contribute to the question of whether there will be enough cobalt to meet future demand. To address this, researchers and manufacturers are actively working on developing battery technologies with reduced or no cobalt content, ensuring a more sustainable and resilient energy storage future.
Is it safe to touch cobalt?
Cobalt should be handled as a CARCINOGEN–WITH EXTREME CAUTION. Cobalt may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. Exposure to Cobalt dust can irritate the skin, eyes, nose and throat.
Cobalt exposure can occur in industrial settings, particularly during the mining and processing of the metal. Prolonged exposure to high levels of cobalt dust or fumes may lead to health issues, including respiratory and dermatological problems. It’s crucial to handle cobalt and its compounds with care, following safety guidelines and using appropriate protective measures when necessary. As with any material, proper handling, awareness of potential risks, and adherence to safety protocols are essential to ensure safe interactions with cobalt.
