Search is on For Cobalt-Free Batteries As Metal Gets Increasingly Rare and Expensive (technologyreview.com)
An anonymous reader writes: Conamix, a little-known startup based in Ithaca, New York, has raised several million dollars to accelerate its development of cobalt-free materials for lithium-ion batteries, the latest sign that companies are eager to find alternatives to the increasingly rare and expensive metal. The problem: The price of cobalt has more than doubled in recent months, as global demand skyrockets for the lithium-ion batteries that power electric vehicles and smartphones. It's also being driven up by the fact that the metal is mined primarily in the Democratic Republic of Congo, where labor and corruption issues are rife. Earlier this year, the nation decided to raise royalties on cobalt and other metals.
Given the ambitious expansion plans of lithium-ion producers, the world will face cobalt shortages by the early 2020s, according to Bloomberg New Energy Finance. This is keeping prices of lithium-ion batteries high and preventing major automakers from lining up long-term supply deals on favorable terms. The mounting threat to electric-vehicle growth has prompted a growing number of companies to explore other solutions.

i've mentioned this before, on other articles that mention lithium batteries and electric vehicles. cobalt is not the only element involved that's in short supply: there isn't enough copper, there isn't enough neodymium, and lithium is a material that explodes when brought into contact with air and water. copper piping and wiring is already stolen from buildings and from church roofs.
neodymium, i don't know if you've ever investigated how it's refined, but it's a radioactive-decay byproduct, meaning that it's only found in amongst *radioactive* deposits (where do you think those are dumped?) and the actual refining itself requires a THOUSAND LITRES of boiling sulphuric acid per 1kg of neodymium. the black market factory photos from remote places in china are shocking... chimney stacks just dumping sulphuric acid fumes directly into the air, and the waste dumped in the nearest river, poisoning the local environment for hundreds of miles downstream.
and we have western governments, whose populations of course do not live anywhere near these mines and factories in Congo or China, banning diesel cars on the basis that they "create pollution", i mean.. .i'm really shocked by the total lack of understanding and appreciation of the true consequences of tthese "environmentally-friendly" decisions.
i've been trying for many years now, but i honestly have absolutely no idea how to get this across to people that we need to trim down the *amount* of materials needed in vehicles. Category L7e "Heavy Quadricycles" such as Riversimple's design concept, the Renault Twizzy and so on, these are perfect: tuned up these small sub-350kg vehicles can go nearly110km/h (70mph), just like some quad-bikes, and that's with only 25HP!
the concept is called "Mass Decompounding", you don't need power-assisted brakes, you don't need power-steering, you can use cross-radial hard silicon compound tires which will last 80,000 miles and have a rolling resistance coeffficient three times less than a standard tire... *all because of the dramatically-reduced weight*. and that reduced weight means a smaller engine, and if it's hybrid or electric it means a smaller battery.
This is why I always wondered why electric car enthusiasts just automatically assumed that battery prices would just keep dropping and dropping. Sometimes as you use more and more of a material or resource, it may begin to become scarcer, thus actually RAISING the price.
Just so people know:
1) The "whistleblower" he refers to is the confessed sabateur.
2) The 9% was a mix of middle management and the being-phased-out Solar City sales division (Tesla's solar division is switching to an exclusive focus on solar roofing products). Tesla has long been criticized for spending too much on SG&A. But of course, expect the shorts to make a fuss when they make SG&A cuts too.
3) The "fire" was something suspicious smouldering in a vent. No impact to production. BTW, I love how you guys focus on every incident, no matter how minor, at Tesla, and completely ignore every issue at every other place, no matter how major. For example, at BMW's SC plant, a worker died from having his head crunched up by a lift. Did you even hear about it?
4) The "tent" is a Sprung building. Cheap, fast, and can last for decades. They're popular for athletic buildings, warehouses, hangars, military applications, mining, etc. There was even one at "Ground Zero" in New York after the terrorist attacks. Reno Tahoe Airport used one for ticketing / checkin / baggage for years.
Re, #2 and #4: please decide on whether you think Tesla is spending too much money or too little so that your arguments can be consistent. Thanks!
I was watching this thing on TV about some guy named Hitler. Someone should stop him!
Indeed, their cathodes tested in at only 3% cobalt by weight, which is mind-bogglingly little. They've stated that they're quickly en route to using no or nearly-no cobalt. Based on the test results so far, I believe it.
