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 challenge 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. automobiles with conventional inner combustion engines. We confirmed fairly comprehensively that, even for those who issue within the CO2 output from battery manufacturing, driving EVs greater than make up the distinction. Even for those who reside someplace that makes use of coal to generate electrical energy, EVs output much less CO2 than automobiles that burn gasoline or diesel. They’re already a greater, cleaner choice than burning fuel and creating tailpipe emissions—that’s an incontrovertible fact.

This month we’re selecting up that thread and looking out 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 could be higher than the fossil-fuel economic system that has triggered distress of its personal.
Battery Supplies
Nearly all of batteries present in EVs as of late use a lithium-ion building. That gives the look that they are all homogenous by way of their composition. In actuality, you may discover infinite 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 number of frequent supplies used to create trendy batteries:
- Lithium: This aspect provides lithium-ion batteries its title. Australia is the world’s main producer, however Chile is available in second, the place the Lithium mining business has created what the Pure Assets Protection Council termed a “water disaster.”
- Cobalt: Used to extend a battery’s power 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 response to Amnesty Worldwide.
- Nickel: Used to extend a battery’s power density. Indonesia is the world’s largest exporter, in response to the USA Worldwide Commerce Fee. The business has been accused of inflicting mass deforestation, rising soil erosion, and water air pollution.
Principally, it’s useful resource extraction; it’s not a reasonably 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
When you 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 range broadly of their building and know-how, however typically, permanent-magnet synchronous motors are thought of probably the most superior. They provide extra effectivity and efficiency than induction motors.
These magnets depend on a number of key parts, like neodymium and dysprosium. These are all a part of a household of parts referred to as uncommon earths, together with some troubling byproduct parts like uranium.
GM Ultium Platform: GM’s 255-kW, everlasting magnet EV motor will likely 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, complete 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 International Witness.
Indicators of Hope
The troubling information above are the darkest side of EV and hybrid manufacturing, a subject that many producers are understandably quiet about.
However there’s cause for hope.
Uncommon earths are typically held to be probably the most troubling part of EV manufacturing, however there are indicators of enchancment, beginning with new, safer sources for uncommon earths. “China is the most important producer and the main participant out there,” Neha Mukherjee instructed me. She’s a senior analyst for uncommon earths at Benchmark Mineral Intelligence. It is her job to look at tendencies within the world market. “Nevertheless, we’re seeing sources of provide developing, particularly in the USA and Australia.”
Mukherjee talked about Elk Creek in Nebraska, plus the Bear Lodge and Halleck Creek initiatives in Wyoming, as being significantly 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 stated. “We positively want extra authorities assist, which they’re already doing by way of insurance policies and by way of capital assist and operational expenditure assist as effectively.”
With that assist, Mukherjee says that a few of these home provides may very well 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 lots of the supplies utilized in batteries and motors is usually a little iffy at occasions, some producers would like you did not know the place they’re sourcing these items. 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 consists of battery passports.
These passports not solely determine the pack’s sourcing, but additionally specify its building sort and the character of cells inside, which is able to make eventual recycling simpler.
In the case of recycling, corporations like Redwood Supplies are placing the frameworks in place to create what sometime is perhaps a round economic 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 automobiles and with such a far much less horrific human toll.
Finally, the supplies which can be so worthwhile when popping out of the bottom are simply as worthwhile when popping out of a wrecked or drained EV. In truth, they’re doubtlessly much more worthwhile, 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, particularly, 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 offer renewed supplies for battery manufacturing.
Redwood not too long ago started building of its first facility to create recycled cathode supplies, which will likely be utilized by the American battery factories from Panasonic and Toyota beginning subsequent yr.
It’s going to be a very long time—many years, possibly—till we will realistically take into consideration making a round economic system. We nonetheless have a number of uncooked supplies to get out of the bottom to get that economic system shifting. However, as soon as we hit a vital variety of electrified automobiles on the street, a big share of recent batteries and motors could be made by the leavings of the outdated automobiles. These batteries may even be repurposed for brand spanking new power storage models to energy properties and buildings in the event that they aren’t appropriate for automobile responsibility. Apart from gathering scrap steel, or possibly repairing a junked engine, that’s simply not one thing that may occur with gas-powered automobiles.
And it’s not one thing that may ever occur if we preserve burning oil.
I do know. All the above is somewhat laborious to course of. Contemplating the clear and disturbing nature of the sourcing of lots of the supplies used within the manufacturing of EVs and hybrids, I feel it is vital to keep in mind that this can be a comparatively new business. 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 vital. Take a look at the worldwide petrochemical economic system, which has been going sturdy for over 100 years. Regardless of infinite laws and protections, that business does incalculable hurt to the atmosphere on daily basis. That is on high of a century of geopolitical strife brought on by black gold.
What’s occurring in Myanmar is a tragedy, however the business 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 occurring once more, and little hope that one other 100 years of oil drilling will enhance the character of that business within the least.
If we decide to getting a clear, round battery economic system proper, we could get to the purpose the place now we have such horrific tradeoffs for our power wants.
