Lithium produced for Tesla’s batteries is less polluting than 31 cups of coffee: researcher

There are many criticisms of electric vehicles like Teslas, and one of them involves the notion that EVs require massive amounts of water to produce the lithium in their batteries. This idea, according to Dr. Maximilian Fichtner, who serves as the Director at the Helmholtz Institute for Electrochemical Energy Storage in Germany, is not accurate at all. 

In a recent conversation with Tagesspiegel Background, the battery researcher stated that the production of electric car batteries is not as extreme as what EV critics would suggest. To produce the lithium needed for a 64 kWh battery pack, for example, Fichtner stated that about 3840 liters of water are evaporated according to usual calculation methods. This is roughly comparable to the production of 250 grams of beef, 30 cups of coffee, or half a pair of jeans, according to the researcher. 

Explaining further, Fichtner stated that even before electric cars like Teslas became popular, lithium was already being used in large quantities in many industrial and chemical processes. Lithium-ion batteries are also widely used in mobile devices, which are universally accepted today. “I’m always surprised that the public never talks about lithium in laptops or mobile phones – but suddenly it’s a problem with the e-car,” the battery researcher said. 

But the water consumption involved in the production of lithium for electric car batteries is just the tip of the iceberg. Fichtner estimates that a 64 kWh pack is likely in the middle of various variants of the Tesla Model 3 sedan, whose long-range versions can easily go beyond 450 km (280 miles) of range per charge. If one were to infer that an electric car battery pack can remain optimal with 2,000 full charging cycles, this could equate to a total distance of about 900,000 km. And that’s with estimates on existing battery technology

With this in mind, it appears that Tesla’s lithium-ion batteries are actually less polluting than otherwise everyday items such as steak or the aforementioned 30 cups of coffee, since they have the potential to remain in service for a very long time. About 2,000 charging cycles, after all, would likely equate to years of average EV use.

Companies like Tesla are hard at work in improving their battery cells. This much is hinted at by Tesla executives such as CEO Elon Musk and President of Automotive Jerome Guillen, both of whom have noted that Tesla’s batteries are always evolving. Fichtner expects electric car batteries to have an average lifespan of 3,000 cycles by 2025, which would make EV batteries even more environmentally-friendly. 

In his recent conversation with the publication, the researcher discussed one of the most sensitive topics surrounding battery production: cobalt. Cobalt has developed a very negative reputation due to the abhorrent conditions in cobalt mines in areas such as Congo. Fortunately, many automakers have since pledged to source the cobalt used in their EVs from areas that meet stringent standards. Tesla does this and more, with the electric car maker attempting to develop cobalt-free batteries in the near future. 

For now, electric car makers are in a game of cobalt reduction, and in this sense, Tesla has a notable lead. The batteries used in Volkswagen’s well-received ID.3 hatchback, for example, contain about 12-14% cobalt. The Tesla Model 3, on the other hand, only contains about 2.9% cobalt as of 2018. Fichtner predicts that if things go well, cobalt-free batteries could enter the market as early as 2025. 

Maximilian Fichtner received his Ph.D. in Chemistry/Surface Science with distinction and the Hermann Billing Award for his thesis in 1992. He currently serves as the professor for Solid State Chemistry at the Ulm University and Executive Director of the Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU). He has also worked in collaboration with the German ministries of Economy and Research and Education, and has served as the Chair of the 1st International Symposium on Magnesium Batteries in 2016.

Tesla lands approval for Robotaxi operation in third U.S. state

On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in.

Tesla has officially landed approval to operate its Robotaxi ride-hailing service in its third U.S. state, as it has landed a regulatory green light from the State of Arizona’s Department of Transportation.

Tesla has been working to expand to new U.S. states after launching in Texas and California earlier this year. Recently, it said it was hoping to land in Nevada, Arizona, and Florida, expanding to five new cities in those three states.

On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in:

Tesla has also been working on approvals in Nevada and Florida, and it has also had Robotaxi test mules spotted in Pennsylvania.

The interesting thing about the Arizona approval is the fact that Tesla has not received an approval for any specific city; it appears that it can operate statewide. However, early on, Tesla will likely confine its operation to just one or two cities to keep things safe and controlled.

Over the past few months, Robotaxi mules have been spotted in portions of Phoenix and surrounding cities, such as Scottsdale, as the company has been attempting to cross off all the regulatory Ts that it is confronted with as it attempts to expand the ride-hailing service.

It appears the company will be operating it similarly to how it does in Texas, which differs from its California program. In Austin, there is no Safety Monitor in the driver’s seat, unless the route requires freeway travel. In California, there is always a Safety Monitor in the driver’s seat. However, this is unconfirmed.

Earlier today, Tesla enabled its Robotaxi app to be utilized for ride-hailing for anyone using the iOS platform.

Tesla ride-hailing Safety Monitor dozes off during Bay Area ride

We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.

A Tesla Robotaxi Safety Monitor appeared to doze off during a ride in the California Bay Area, almost ironically proving the need for autonomous vehicles.

The instance was captured on camera and posted to Reddit in the r/sanfrancisco subreddit by u/ohmichael. They wrote that they have used Tesla’s ride-hailing service in the Bay Area in the past and had pleasant experiences.

However, this one was slightly different. They wrote:

“I took a Tesla Robotaxi in SF just over a week ago. I have used the service a few times before and it has always been great. I actually felt safer than in a regular rideshare.

This time was different. The safety driver literally fell asleep at least three times during the ride. Each time the car’s pay attention safety alert went off and the beeping is what woke him back up.

I reported it through the app to the Robotaxi support team and told them I had videos, but I never got a response.

I held off on posting anything because I wanted to give Tesla a chance to respond privately. It has been more than a week now and this feels like a serious issue for other riders too.

Has anyone else seen this happen?”

My Tesla Robotaxi “safety” driver fell asleep
byu/ohmichael insanfrancisco

The driver eventually woke up after prompts from the vehicle, but it is pretty alarming to see someone like this while they’re ultimately responsible for what happens with the ride.

We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.

They should have probably left the vehicle immediately.

Tesla’s ride-hailing service in the Bay Area differs from the one that is currently active in Austin, Texas, due to local regulations. In Austin, there is no Safety Monitor in the driver’s seat unless the route requires the highway.

Tesla plans to remove the Safety Monitors in Austin by the end of the year.

Tesla opens Robotaxi access to everyone — but there’s one catch

Tesla has officially opened Robotaxi access to everyone and everyone, but there is one catch: you have to have an iPhone.

Tesla’s Robotaxi service in Austin and its ride-hailing service in the Bay Area were both officially launched to the public today, giving anyone using the iOS platform the ability to simply download the app and utilize it for a ride in either of those locations.

It has been in operation for several months: it launched in Austin in late June and in the Bay Area about a month later. In Austin, there is nobody in the driver’s seat unless the route takes you on the freeway.

In the Bay Area, there is someone in the driver’s seat at all times.

The platform was initially launched to those who were specifically invited to Austin to try it out.

Tesla confirms Robotaxi is heading to five new cities in the U.S.

Slowly, Tesla launched the platform to more people, hoping to expand the number of rides and get more valuable data on its performance in both regions to help local regulatory agencies relax some of the constraints that were placed on it.

Additionally, Tesla had its own in-house restrictions, like the presence of Safety Monitors in the vehicles. However, CEO Elon Musk has maintained that these monitors were present for safety reasons specifically, but revealed the plan was to remove them by the end of the year.

Now, Tesla is opening up Robotaxi to anyone who wants to try it, as many people reported today that they were able to access the app and immediately fetch a ride if they were in the area.

We also confirmed it ourselves, as it was shown that we could grab a ride in the Bay Area if we wanted to:

The launch of a more public Robotaxi network that allows anyone to access it seems to be a serious move of confidence by Tesla, as it is no longer confining the service to influencers who are handpicked by the company.

In the coming weeks, we expect Tesla to then rid these vehicles of the Safety Monitors as Musk predicted. If it can come through on that by the end of the year, the six-month period where Tesla went from launching Robotaxi to enabling driverless rides is incredibly impressive.
