Issues are solely getting hotter within the political furnaces as we get nearer to election day. Regardless of former president and present Republican nominee Donald Trump giving some concessions to Elon Musk in trade for his endorsement, EVs are extra of a hot-button concern than ever.
If something, the misinformation campaigns on the market are accelerating, so we’ll preserve doing our half by digging into what’s actual and what’s not.
Final month, we dug deep into the CO2 impression of driving EVs vs. vehicles with conventional inner combustion engines. We confirmed fairly comprehensively that, even when you issue within the CO2 output from battery manufacturing, driving EVs greater than make up the distinction. Even when you reside someplace that makes use of coal to generate electrical energy, EVs output much less CO2 than vehicles that burn gasoline or diesel. They’re already a greater, cleaner choice than burning gasoline and creating tailpipe emissions—that’s an incontrovertible fact.

This month we’re choosing up that thread and searching into the opposite environmental implications of EVs (and, by extension, hybrids). Particularly, we’ll delve into the sourcing of lots of the extra problematic supplies utilized in battery and electrical motor manufacturing.
Honest warning: The outcomes for this one will not be fairly so rosy, however we’re not right here to sugar-coat the reality. We’re right here to seek out it—together with the explanations to be optimistic as effectively about how what’s subsequent may be higher than the fossil-fuel financial system that has precipitated distress of its personal.
Battery Supplies
Nearly all of batteries present in EVs lately use a lithium-ion building. That gives the look that they are all homogenous when it comes to their composition. In actuality, you will discover countless variation in materials composition throughout the cells tucked within the modules that make up the batteries that make an EV go.
Nonetheless, there are a couple of widespread supplies used to create fashionable batteries:
- Lithium: This ingredient offers lithium-ion batteries its identify. Australia is the world’s main producer, however Chile is available in second, the place the Lithium mining trade has created what the Pure Sources Protection Council termed a “water disaster.”
- Cobalt: Used to extend a battery’s vitality density and stability. The Democratic Republic of the Congo is the world’s main producer, the place the mining has led to “grievous human rights abuses,” in accordance with Amnesty Worldwide.
- Nickel: Used to extend a battery’s vitality density. Indonesia is the world’s largest exporter, in accordance with america Worldwide Commerce Fee. The trade has been accused of inflicting mass deforestation, rising soil erosion, and water air pollution.
Mainly, it’s useful resource extraction; it’s not a fairly factor. We get oil from undersea drilling, fracking and from international locations mired in—or behind—battle all around the world. As we’ll cowl in a bit, there’s extra of a path for true sustainability with EVs that do not exist within the fossil-fuel sector, however we’re solely now beginning to stroll it.

Uncommon Earth Supplies
For those who assume the sourcing of batteries is somewhat uncomfortable, this one’s going to be even heavier.
The electrical motors utilized in EVs and hybrids once more fluctuate broadly of their building and expertise, however usually, permanent-magnet synchronous motors are thought-about essentially the most superior. They provide extra effectivity and efficiency than induction motors.
These magnets depend on a couple of key parts, like neodymium and dysprosium. These are all a part of a household of parts known as uncommon earths, together with some troubling byproduct parts like uranium.
GM Ultium Platform: GM’s 255-kW, everlasting magnet EV motor can be used for efficiency all-wheel drive and rear-wheel drive functions.
The rarity of those parts and their relative worth has resulted in some extraordinarily unsavory methods used to extract the stuff. In Myanmar, one of many world’s main sources, entire villages have been wiped off the map by mining operations, with the previous inhabitants bullied into submission.
It is a disturbing actuality you may learn extra about at World Witness.
Indicators of Hope
The troubling details above are the darkest side of EV and hybrid manufacturing, a subject that many producers are understandably quiet about.
However there’s motive for hope.
Uncommon earths are usually held to be essentially the most troubling part of EV manufacturing, however there are indicators of enchancment, beginning with new, safer sources for uncommon earths. “China is the largest producer and the key participant available in the market,” Neha Mukherjee advised me. She’s a senior analyst for uncommon earths at Benchmark Mineral Intelligence. It is her job to look at traits within the world market. “Nevertheless, we’re seeing sources of provide developing, particularly in america and Australia.”
Mukherjee talked about Elk Creek in Nebraska, plus the Bear Lodge and Halleck Creek initiatives in Wyoming, as being notably promising home sources for these supplies.
New sources in Africa, Australia, and North America have the potential to be main world producers whereas providing much better environmental, social, and governance (ESG) practices than many present mines.
“Lower than 1% of the dysprosium provide that’s all coming from Myanmar is ESG compliant, which is regarding,” she mentioned. “We undoubtedly want extra authorities assist, which they’re already doing when it comes to insurance policies and when it comes to capital assist and operational expenditure assist as effectively.”
With that assist, Mukherjee says that a few of these home provides could possibly be on-line as quickly as 2027.
What’s even higher than environmentally acutely aware sources for uncommon earths? How about not needing them? Loads of corporations are engaged on high-efficiency motors that do not use uncommon earths, together with Tesla. Nevertheless, we’re nonetheless ready to see that vaunted motor take form.
Since sourcing most of the supplies utilized in batteries and motors could be a little iffy at instances, some producers would like you did not know the place they’re sourcing these things. Fortunately, that is altering.
Battery passports will make it abundantly clear what supplies are used within the manufacturing of the battery, and the place they have been sourced. Volvo is one chief in battery passports, beginning with the long-awaited EX90 SUV. Tesla’s Cybertruck additionally contains battery passports.
These passports not solely establish the pack’s sourcing, but in addition specify its building kind and the character of cells inside, which can make eventual recycling simpler.
In terms of recycling, corporations like Redwood Supplies are placing the frameworks in place to create what sometime is likely to be a round financial system for these troubling supplies—in different phrases, constructing an ecosystem the place we have to extract far much less of them for brand spanking new vehicles and with such a far much less horrific human toll.
In the end, the supplies which might be so beneficial when popping out of the bottom are simply as beneficial when popping out of a wrecked or drained EV. The truth is, they’re probably much more beneficial, as a result of as an alternative of getting to extract them from the earth, they’re all proper there in a handy bundle, simply ready to be renewed.
Redwood, specifically, is making waves, elevating billions in investments whereas increasing its facility in Nevada and constructing a brand new one in South Carolina. Based by former Tesla Chief Technical Officer and pioneering battery engineer J.B. Straubel, the corporate has contracts with many main producers to not solely settle for batteries for recycling however to supply renewed supplies for battery manufacturing.
Redwood not too long ago started building of its first facility to create recycled cathode supplies, which can be utilized by the American battery factories from Panasonic and Toyota beginning subsequent yr.
It’s going to be a very long time—a long time, perhaps—till we are able to realistically take into consideration making a round financial system. We nonetheless have quite a lot of uncooked supplies to get out of the bottom to get that financial system shifting. However, as soon as we hit a crucial variety of electrified autos on the highway, a major proportion of recent batteries and motors may be made by the leavings of the outdated vehicles. These batteries may even be repurposed for brand spanking new vitality storage items to energy properties and buildings in the event that they aren’t appropriate for automobile responsibility. Apart from amassing scrap metallic, or perhaps repairing a junked engine, that’s simply not one thing that may occur with gas-powered vehicles.
And it’s not one thing that can ever occur if we preserve burning oil.
I do know. The entire above is somewhat exhausting to course of. Contemplating the clear and disturbing nature of the sourcing of most of the supplies used within the manufacturing of EVs and hybrids, I feel it is necessary to keep in mind that this can be a comparatively new trade. EVs have solely been mainstream for a decade. Similar to the programs wanted to make batteries, establishing a recycling infrastructure will take time.
That does not excuse these points. Removed from it.

However context is necessary. Have a look at the worldwide petrochemical financial system, which has been going sturdy for over 100 years. Regardless of countless rules and protections, that trade does incalculable hurt to the surroundings every single day. That is on high of a century of geopolitical strife brought on by black gold.
What’s taking place in Myanmar is a tragedy, however the trade is shifting in direction of higher sourcing for these supplies, many coming on-line in just some years. In the meantime, there’s nothing stopping Deepwater Horizon from taking place once more, and little hope that one other 100 years of oil drilling will enhance the character of that trade within the least.
If we decide to getting a clear, round battery financial system proper, we could get to the purpose the place we now have such horrific tradeoffs for our vitality wants.
