If That Tesla Battery Could Talk

Let’s imagine what an EV battery could tell us about its reality. A short story.  H/T Graeme Weber

The packed auditorium was abuzz; nobody seemed to know what to expect. The only hint was a large aluminum block sitting on a sturdy table on the stage.

When the crowd settled down, a scholarly-looking man walked out and put his hand on the shiny block, “Good evening,” he said, “I am here to introduce NMC532-X,” and he patted the block, “we call him NM for short,” and the man smiled proudly. “NM is a typical electric vehicle (EV) car battery in every way except one; we programmed him to send signals of the internal movements of his electrons when charging, discharging, and in several other conditions. We wanted to know what it feels like to be a battery. We don’t know how it happened, but NM began to talk after we downloaded the program.

“Despite this ability, we put him in a car for a year and then asked him if he’d like to do presentations about batteries. He readily agreed on the condition he could say whatever he wanted. We thought that was fine, and so, without further ado, I’ll turn the floor over to NM;” the man turned and walked off the stage.

“Good evening,” NM said. He had a slightly affected accent, and when he spoke, he lit up in different colors.

“A few days ago, at the start of my last lecture, three people walked out. But here is what I noticed about them. One was wearing a battery-powered hearing aid, one tapped on his battery-powered cell phone as he left, and a third got into his car — which would not start without a battery. So, I’d like you to think about your day for a moment; how many batteries do you rely on?”

He paused for a full minute which gave people time to count their batteries. Then he went on, “Now, it is not elementary to ask, ‘what is a battery?’ I think Mr. Tesla said it best when they called us Energy Storage Systems. That’s important. We do not make electricity — we store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators. So, to say an EV is a zero-emission vehicle is not at all valid. Also, since 40% of the electricity generated in the U.S. is from coal-fired plants, it follows that 40% of the EVs on the road are coal-powered, n’est-ce pas?”

He flashed blue again. “Einstein’s formula, E=MC2, tells us it takes the same amount of energy to move a 5,000 lb. gasoline-driven automobile a mile as it does an electric one. The only question again is, what produces the power? To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car.”

He lit up red when he said that, and then he continued in blue and orange. “Mr. Elkay introduced me as NMC532. If I were the battery from your computer mouse, Elkay would introduce me as AA, if from your cell phone as CR2032, and so on. We batteries all have the same name depending on our design. By the way, the ‘X’ in my name stands for ‘experimental.’

“There are two orders of batteries: rechargeable and single use. The most common single-use batteries are A, AA, AAA, C, D, 9V, and lantern types. Those dry-cell species use zinc, manganese, lithium, silver oxide, or zinc and carbon to store electricity chemically. Please note they all contain toxic, heavy metals.

“Rechargeable batteries only differ in their internal materials, usually lithium-ion, nickel-metal oxide, and nickel-cadmium.

“The United States uses three billion of these two battery types a year, and most are not recycled; they end up in landfills. If you throw your small, used batteries in the trash, here is what happens to them.

“All batteries are self-discharging. That means even when not in use, they leak tiny amounts of energy. You have likely ruined a flashlight or two from an old, ruptured battery. When a battery runs down and can no longer power a toy or light, you think of it as dead; well, it is not. It continues to leak small amounts of electricity. As the chemicals inside it run out, pressure builds inside the battery’s metal casing, and eventually, it cracks. The metals left inside then ooze out. The ooze in your ruined flashlight is toxic, and so is the ooze that will inevitably leak from every battery in a landfill. All batteries eventually rupture; it just takes rechargeable batteries longer to end up in the landfill.

“In addition to dry-cell batteries, there are also wet-cell ones used in automobiles, boats, and motorcycles. The good thing about those is, 90% of them are recycled. Unfortunately, the cost of recycling EV batteries is more expensive than the cost of mining and creating a new battery. EV batteries that don’t have enough potency to power a vehicle can sometimes be used to power home appliances, street lights or solar panel backup until they finally lose all their energy.

“But that is not half of it. For those of you excited about electric cars and a green revolution, I want you to take a closer look at batteries and windmills and solar panels. These three technologies share what we call environmentally destructive embedded costs.”

NM got redder as he spoke. “Everything manufactured has two costs associated with it: embedded costs and operating costs. I will explain embedded costs using a can of baked beans as my subject.

“In this scenario, baked beans are on sale for $1.75 a can. As you head to the checkout, you begin to think about the embedded costs in the can of beans.

“The first cost is the diesel fuel the farmer used to plow the field, till the ground, harvest the beans, and transport them to the food processor. Not only is his diesel fuel an embedded cost, so are the costs to build the tractors, combines, and trucks. In addition, the farmer might use a nitrogen fertilizer made from natural gas.

“Next is the energy costs of cooking the beans, heating the building, transporting the workers, and paying for the vast amounts of electricity used to run the plant. The steel can holding the beans is also an embedded cost. Making the steel can requires mining taconite, shipping it by boat, extracting the iron, placing it in a coal-fired blast furnace, and adding carbon. Then it’s back on another truck to take the beans to the grocery store. Finally, add in the cost of the gasoline for your car.

“But wait — can you guess one of the highest but rarely acknowledged embedded costs? It’s the depreciation on the 5000-lb. car you used to transport one pound of canned beans!”

“But that can of beans is nothing compared to me! I am hundreds of times more complicated. My embedded costs not only come in the form of energy use; they come as environmental destruction, pollution, disease, child labor, and the cost to be recycled.”

He paused, “I weigh 1,000 pounds, and as you see, I am about the size of a travel trunk. I contain 25 pounds of lithium, 60 pounds of nickel, 44 pounds of manganese, 30 pounds cobalt, 200 pounds of copper, and 400 pounds of aluminum, steel, and plastic. Inside me are 6,831 individual lithium-ion cells.

“It should concern you that all those toxic components come from mining. For instance, to manufacture EACH auto battery like me, you must process 25,000 pounds of brine for the lithium, 30,000 pounds of ore for the cobalt, 5,000 pounds of ore for the nickel, and 25,000 pounds of ore for copper. All told, you dig up 500,000 pounds of the earth’s crust for just. one. battery.

“I mentioned disease and child labor a moment ago. Here’s why. Sixty-eight percent of the world’s cobalt, a significant part of a battery, comes from the Congo. Their mines have no pollution controls, and they employ children who die from handling this toxic material. Should we factor in these diseased kids as part of the cost of driving an electric car?”

“Finally, “I’d like to leave you with these thoughts. California is building the largest battery in the world near San Francisco, and they intend to power it from solar panels and windmills. They claim this is the ultimate in being ‘green,’ but it is not! This construction project is creating an environmental disaster. Let me tell you why.

“The main problem with solar arrays is the chemicals needed to process silicate into the silicon used in the panels. To make pure enough silicon requires processing it with hydrochloric acid, sulfuric acid, nitric acid, hydrogen fluoride, trichloroethane, and acetone. In addition, they also need gallium, arsenide, copper-indium-gallium-diselenide, and cadmium-telluride, which also are highly toxic. Silicon dust is a hazard to the workers, and the panels cannot be recycled.

“Windmills are the ultimate in embedded costs and environmental destruction. Each weighs 1688 tons (the equivalent of 23 houses) and contains 1300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass, and the hard to extract rare earths neodymium, praseodymium, and dysprosium. Each blade weighs 81,000 pounds and will last 15 to 20 years, at which time it must be replaced. We cannot recycle used blades. Sadly, both solar arrays and windmills kill birds, bats, sea life, and migratory insects.

“There may be a place for these technologies, but you must look beyond the myth of zero emissions. I predict EVs and windmills will be abandoned once the embedded environmental costs of making and replacing them become apparent. I’m trying to do my part with these lectures.”

    Replacing combustion with combustibility doesn’t make EV batteries as clean or green as is claimed.

    The Moss Landing facility has been in the news a few times this year-
    1) The CPUC just approved an addition at the facility:

    2) The facility was shut down due to fires earlier in the year-

    A few years ago PG&E upgraded the transmission infrastructure at the site. A report on the failure of a transmission tower was published:

    The facilities failures aren’t going to help the Bay Area cites score well on their “affordable renewable energy goals”-

    Really great post Ron

    have you ever thought of publishing a collection of your posts
    similar to what Antony has just done with Climate at a Glance

    I think you should
    if nothing else you could turn them into a pdf

    If you are interested you could email me and I will give you some tips about using python to fit co2 v temp
    or perhaps you already know

      Thanks Jeremy. I am just a spreadsheet jockey with no Python experience, and too old a dog to learn more than a few tricks. I have previously thought about an anthology collection. It led to a directory of the content, but the thought of compiling into a single volume is intimidating. It is also the case that most readers respond to a pointed post rather than a comprehensive lengthy discussion. I will think some more about this.

    @ Ron:
    I prefer to buy a real book whenever possible. Even a collection of booklets or magazines appeals to me more than a web page (even if I print it out and put it in a binder). Web pages seem so temporary. All kinds of things have to be in place and operating for any given web page to be available for a long period of time. But a book can still be read and studied even if your battery dies, the power goes out, an EMP knocks out the internet, devices and operating systems become incompatible, or tyrants decide the masses don’t need to inform themselves of alternative viewpoints anymore.

    Books often contain an index, which helps a reader to return to something significant, even years later than the first reading.

    Books hold a place in time and space that web pages can only dream of. Censors can quickly and easily eliminate web-based commentary that they dislike, but books take a lot more effort to eliminate.

    At any rate, thanks for putting this article out there. I’ve already printed it. 😉

    Very good post. Thank you. I would, for completeness, also note that solar and wind have enormous land requirements compared to fossil fuels and nuclear.

    Great and comprehensive, clear post.
    I now imagine a congress where the NM gives that presentation, but also Dr PV panel, Mr Data Centre MBA, and many other talk about how the help and contribute to destroy humans’ way of life and environment
