In one other current article, I explored how Ford is taking the Tesla method to EVs, not solely with its not too long ago introduced adoption of Tesla’s NACS plug, but in addition in a previously-discussed method to automobile effectivity. Ford isn’t going to waste money and time making an attempt to supply 600-mile EVs, however it will give attention to getting sufficient vary via a mixture of environment friendly autos and good charging infrastructure.
However, a gaggle of researchers on the Norwegian College of Science and Know-how suppose even this may not be sufficient to maintain the business out of bother. Within the majority of worldwide eventualities and authorities targets for decreasing carbon emissions within the transportation sector, battery-powered electrical autos are seen as a major factor of the answer. To supply adequate batteries for this transition to low-emission autos, huge portions of uncooked supplies are required.
Lithium, a vital ingredient in all EV batteries, performs an important position in making certain entry to those sources, as a result of all main battery chemistries depend on it.
“It appears very seemingly we’ll have a scarcity. The important thing lies within the demand. The demand must lower to keep away from long-term provide issues,” says Fernando Aguilar Lopez, a PhD candidate on the Norwegian College of Science and Know-how’s (NTNU) Division of Power and Course of Engineering.
Whereas there’s a variety of lithium around the globe, the researchers have found out that there simply gained’t be sufficient to go round, even when all of us selected LEAFs as an alternative of Cybertrucks.
Fernando Aguilar Lopez makes a speciality of analyzing international materials flows, inspecting uncooked supplies cycles from extraction to manufacturing, utilization, and disposal. Together with postdoc Romain Billy and Professor Daniel B. Müller, he has developed a cloth circulation evaluation mannequin known as MATILDA (MATerIaL Demand and Availability). This mannequin was not too long ago launched within the journal Sources, Conservation & Recycling.
The research explores methods for managing useful resource utilization in EV batteries. MATILDA aids in understanding the essential components influencing useful resource provide and calculates how totally different interventions may assist mitigate future demand. MATILDA stands as essentially the most complete mannequin so far for battery uncooked supplies within the international automobile fleet. In accordance with Müller, instruments like this will play a significant position in serving to business and policymakers develop methods to make sure safe and resilient essential uncooked supplies provide chains.
In case you love large battery EVs, and also you’re seeking to discover the research to nit-pick its eventualities, I’ve much more unhealthy information: the staff used over 8,000 totally different eventualities to check this, and all of it factors the identical means. The researchers recommend that in an effort to forestall extreme demand for particular person metals, investments ought to be made in a broader vary of latest battery applied sciences. Moreover, the main target shouldn’t be on producing extra, bigger, and heavier electrical vehicles. As an alternative, it could be useful for extra individuals to share smaller vehicles with lower-capacity battery packs.
“Extending the lifespan of autos and batteries by facilitating reuse and alternative may even be essential in decreasing the demand for uncooked supplies,” says Aguilar Lopez.
No Silver Bullets Are Accessible To Save The Day
Sadly, LiFePO (aka LFP) batteries aren’t a magic bullet, both. They’re nice, not as a result of they keep away from lithium use (they don’t), however as a result of they assist evade bottlenecks of different supplies. However, they exchange issues like nickel and cobalt with phosphorous, and we’d like phosphorous to develop meals! Utilizing an excessive amount of of that might actually harm farmers economically and drive up meals costs globally.
The NTNU research reveals that regardless of its significance, recycling won’t considerably alleviate the strain on uncooked supplies within the subsequent decade. It is because our present EVs are comparatively new, and a big variety of them gained’t be accessible for recycling till 10 to fifteen years from now.
However, MATILDA demonstrates that main demand could be decreased by enhancing the effectivity of recycling lithium, aluminum, manganese, and phosphorus. These supplies are presently uneconomical to recycle and are usually not encompassed within the newest EU battery rules.
Strong-state batteries are unlikely to be in the marketplace in time, and even they’ve issues if we had been to shove them into service by some miracle. “Really, solid-state batteries can worsen the state of affairs, requiring extra lithium per kilowatt hour — virtually twice as a lot in some circumstances,” Aguilar Lopez stated.
What Can We Do?
The research affords a variety of options, and I’m going to combine them with a few of my very own right here.
The plain factor is that whenever you discover the ground flooding in your lavatory, you’ve received to show the water off earlier than you attain for the mop. That signifies that something we are able to do to scale back battery sizes in EVs, and even preserve them from turning into even larger, is essential to getting via the following decade or two. That’s not sufficient, however it’s higher than making the issue worse.
We’ve additionally received to search for methods to give attention to smaller batteries extra.
For EVs, this implies making an attempt to advertise a “much less is extra” method. It will require elevated effectivity, a TON extra charging stations, and autos which are extra environment friendly on the freeway (most likely through multi-speed drive items). There’s additionally a cultural ingredient — our dependancy to bigger SUVs is simply not nice right here.
It’s additionally essential to look past vehicles, however that doesn’t essentially imply forcing individuals to trip the bus or the practice. Micromobility, particularly e-bikes, is a giant a part of getting individuals from A to B with out large batteries that the world simply can’t afford too lots of proper now. Additionally, issues like ride-share providers, the place persons are sharing these batteries, is an effective factor to encourage. In-between options, like mini-EVs, are additionally price wanting extra into.
However, doing any of this requires infrastructure, and that requires spending cash. Charging stations aren’t low cost, and we’ll seemingly must go a methods past what the NEVI (Infrastructure Invoice) funds can pay for. Bike infrastructure, no less than GOOD bike infrastructure, additionally isn’t as low cost as portray a line or stamping on “sharrows.”
However, all of this can be a lot cheaper than doing nothing. If the battery provide all goes to present rich individuals 200+ kWh batteries, all people else will preserve burning gasoline. Given the place I’m scripting this, I don’t suppose I want to enter nice element on the entire unhealthy issues that come from that end result!

Former Tesla Battery Skilled Main Lyten Into New Lithium-Sulfur Battery Period — Podcast:
I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, however it all the time felt flawed — and it was all the time robust to resolve what we must always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer individuals learn it! We simply do not like paywalls, and so we have determined to ditch ours.
Sadly, the media enterprise remains to be a tricky, cut-throat enterprise with tiny margins. It is a unending Olympic problem to remain above water and even maybe — gasp — develop. So …
