Why Lithium Is Dangerous But PERFECT For Batteries

Our chemistry book has a diagram of a battery in the electrochemistry chapter, and I discuss that battery for a bit before explaining to my students that the basics of ACME (anode, cathode, metallic path, electrolyte) hold for every battery but that the engineering of modern lithium-ion batteries is far different from the diagram in the book.

This video - again leaning into the algorithm-rewarded longer and longer format - explains some battery basics involving the activity series, the history of the development of the lithium-ion battery, and the methods of fiery failure when the battery overheats.

This is, as Dr Derek says, a technology that has allowed our modern, battery-dependent world.

High demand and prices for lithium send mines into overdrive

Source - NPR article

We need lithium.

We didn't used to need nearly as much lithium as we do now, and we're going to need way more lithium going forward because lithium is used to make pretty much every high tech battery - like those in electric vehicles. Those batteries need a whole lot of lithium.

I've posted about the one lithium mine in the United States and how it's running into conflicts with environmentalists over the destruction of habitat for Tiehm's buckwheat.

Today's article from NPR - which also has a 7-minute audio story in case you'd rather just listen to the story - shows some photos from the aforementioned Silver Peak mine in Nevada and explores other possible sources of lithium including seawater and geothermal power plant brine. Sadly they don't go into the reason lithium is so useful: its position at the top of the activity series and its relative low density making it a great way to store energy in small masses.

Electric Vehicles' Battery Problem

"To replace the UK (not the UK) 31.5 million gasoline cars will require 236,000 tons of lithium carbonate." ~ quote from about 1:00 in the above video.

That would - again, according to the video - require all the world's output for 9 months.

And that metal comes from some countries with awful human rights records and workers' protections.

Then, if we mine the US's lithium, we have to use up water and leach arsenic into the water supply of Nevada...and dig into land holy to Native Americans...and destroy habitat for endangered animals.

It's the frickin' Kobayashi Maru, man.

Then we have to look at the cobalt mining.

To quote a magnet I got from the University of Utah, "what's your is mined," but clearly what's mined is bad for the planet and people.
