Electric Car Battery Problems
The International Energy Agency (IEA) tells us that an electric vehicle requires six times the mineral inputs of a gasoline-powered vehicle. EV lithium-ion battery packs are made with materials that are expensive, and in some cases, toxic and flammable. Primary materials include lithium, nickel, cobalt, and copper. The mining of these rare materials, their manufacturing processes, and their eventual disposal all pose very real environmental challenges.
While 90 percent of average gasoline-powered vehicle batteries are recycled, only five percent of EV lithium-ion batteries are recycled. While oil is exclusively mined underground in specific areas, the components for lithium-ion batteries are obtained through open pit mining that damages wide areas of the natural environment. Let’s look at how these materials are collected.
Nickel is a major component of
EV batteries and is found in the Rainforests of Indonesia. It resides just below the topsoil and is extracted using a method of horizontal surface mining.
Harmful effects include removal of topsoil, extreme environmental degradation, and deforestation. We’re not really saving the planet with this process. Since the Rainforests are the lungs of our planet, this is harming the process of removing Carbon Dioxide from the atmosphere.
Lithium mining is also a major culprit. Over half of the world’s lithium is found in Chile, Bolivia, and Argentina, known as the “Lithium Triangle.” The Institute for Energy Research tells us that lithium is found in salt flats in arid areas and the material has to be mined from under these salt flats.
Lithium extraction can take 18 months through an evaporation process that uses enormous amounts of water. Each ton of refined lithium uses up 500,000 gallons of water. The results deplete the water table and cause soil contamination.
Another major component of Electric Car batteries is cobalt and 70 percent of cobalt comes from the Democratic Republic of the Congo. While cobalt mining has a similar process as lithium mining, add to this a list of severe human rights violations for hazardous working conditions and child labor. Cobalt is a toxic metal. Prolonged exposure and inhalation of cobalt dust can lead to health issues related to the skin, eyes, and lungs.
Cobalt mining in the Congo involves workers of all ages. Of the 255,000 current workers, over 40,000 are children and some are as young as six-years-old. According to Amnesty International, “Thousands of children mine cobalt in the Democratic Republic of the Congo. Despite the potentially fatal health effects of prolonged exposure, adult and child miners work without even the most basic protective equipment.” The majority of these mines are owned by Chinese companies.
Copper is also used in EV batteries and most of it comes from open-pit strip mines in Chile. This sort of mining negatively impacts topsoil, vegetation, wildlife habitats, and groundwater.
The Impact of Lithium-Ion Batteries for Cars
According to IHS Markit, in the year 2000, nine percent of lithium produced was used for EV batteries. By 2020, this share rose to 66 percent and will reach over 90 percent by 2030. An electric vehicle such as a Tesla Model S contains 63kg of lithium.
As mentioned earlier, lithium mining uses a lot of water. Mining companies in Chile’s Salar de Atacama, one of the driest places on Earth uses 65 percent of the region’s water. Plus, the process of lithium mining uses toxic chemicals which can contaminate streams, crops, and wildlife, adding to the decline of endangered species such as flamingos.
Lithium mining also creates what researchers call “the colonial shadow of green electromobility.” This is the impact that lithium mining has on the local environment and inhabitants in Latin America. The assertion indicates that lithium mining replicates the historical inequities between the Northern and Southern hemispheres in regard to impacting indigenous Andean territories
The Downside of EV Charging
The adoption of all-electric vehicles is happening all around the world, but experts say it is happening too slow to prevent the worst of climate change. The problem is not related to consumers buying EVs, but rather to the slow roll-out of infrastructure to support charging.
According to a recent study, the current rate of EV adoption will not have a noticeable impact on climate change. In order for the benefits to become visible, we’ll need to
step up the number of charging stations that are available to consumers.
Eric Hannon, partner in McKinsey's Center for Future Mobility and co-author of Mobility's Net-Zero Transition: A Look at Opportunities and Risks tells us, “How we get there is not written in stone. Frankly, we're moving too slow. We aren't on a trajectory that gets us there yet.”
Hannon explains that in Europe, over 10,000 chargers per week would need to be added in order for the 2030 climate targets to be achieved. If carbon emissions don’t start declining by 2025, then according to his research, EVs’ impact on climate change won’t be enough to keep the temperature rise to under 1.5 degrees this century.
Currently, all-electric vehicles make up eight percent of new car sales in Europe, while the sale of Hybrids, Plug-in Hybrids, and Electric Vehicles in America has reached ten percent. Hannon has concluded that while a lot of people recognize the problem of climate change and are prepared to go electric, “If we wait 10 years or 15 years to start thinking about this and start acting in earnest, it’s too late.”
As EV adoption rapidly increases, concerns surrounding environmental impact and how we get materials for EV batteries are being addressed. Learn more here.

Mines may also contain
pools of wastewater that can potentially pour into local waterways. For example, in its
2016 report, China Water Risk highlighted an abandoned mine in Ganzhou where untreated chemicals flow from leaching ponds when it rains.
Problems in China
The pollution resulting from rare-earth mining has created soil incapable of supporting crops and water supplies have been contaminated.
Chinese officials have attempted to counteract these threats by shutting down a large number of mines, especially the smaller and the illegal ones, but there are still severe, large-scale threats that remain unresolved.
Rare-earth mining is notorious for the environmental hazards it poses but researchers in China are making breakthroughs that could turn the tide.

T
he mining and processing of Earth Elements in northern China has caused years of toxic leaking into surrounding water sources. A tailings pond lies on the west of the Chinese city Baotou, one filled with a black grey sludge of toxic and radioactive material. It is the by-product of rare earth processing - elements vital to solar energy, wind farms and other alternative energy sources. It is open to the air but worse it is seeping into the ground below, poisoning the water. Sky's China Correspondent Tom Cheshire was followed when he tried to gather more information.
