Tesla Factory May Get Greener Raw Materials For Its Batteries From Arizona

Southwestern States like Texas and New Mexico aren’t the only ones vying for a piece of the Tesla Gigafactory pie. Last week American Manganese Inc., a new Arizona company with the only domestic supply of electrolytic manganese metals (EMM), announced its interest in supplying the Tesla Factory with raw materials for its lithium ion batteries.

“It is my belief that Tesla’s project is concrete evidence of the growth and viability of the electric car market, resulting in greater demand for lithium ion batteries,” said Larry W. Reaugh, president and chief executive officer of American Manganese Inc. “The need for secure metal feed stocks used to make these batteries; such as Manganese, Cobalt, Lithium, Carbon, and others; will correspondingly increase to meet the soaring electric vehicle demand.” Of course, a deal with Tesla for supplies would obviously mean great things for any company- especially a new and growing American mine company. Still, American Manganese offers a low-cost, more environmentally-friendly product that Tesla shouldn’t pass up.

In 2011, over 97% of global EMM production was sourced from China with South Africa accounting for the remaining 2.1% of global supply. The lack of a domestic supply worried those who wanted to see the EV market succeed in the United States because prices for EMM were just too high for U.S. companies. At that time China and South Africa produced EMM at $1.30/lb, but the price in the U.S. was $1.80/lb with the 14% import duty. American Manganese’s recent entry onto the scene of EMM suppliers is great news for companies like Tesla and GM. The mining company describes itselfas focused on becoming the lowest cost producer of EMM.

They might meet that goal, too- since a Preliminary Economic Assessment 2009 study completed for American Manganese estimated cost per pound of EMM production at just $0.44!

The American mining company also provides a product with a reduced environmental impact. Just last year, the company received a patent for its manganese recovery process. With this unique process, the company is able to recover manganese from a low-grade resource with significantly less energy and lower water use than conventional processing methods. The mining process also ends up with benign toxicity in tailings, which can be replaced immediately into reclamation areas. Because American Manganese can supply Tesla with a low-cost, greener, and objectively cheaper EMM supply, it would be surprising if the company didn’t become Tesla’s raw materials supplier, and this may make Arizona even more attractive to the car manufacturer, despite the State’s political leanings.

Arizona already proposed a bill to legalize direct sales of Tesla electric cars and the City of Tuscon has submitted a formal proposal to Tesla to become the host site. What more can Arizona do to win Elon Musk’s love?

Maybe its time for Musk to let his other courters — Nevada, New Mexico, and Texas — down easy.

    There are about seven pounds of manganese in a typical American car, so if the cost could be dropped to 44 cents a pound it would save on average over $9 per vehicle. Of course getting the price down to 44 cents a pound might be optimistic, but any decrease would be welcome.

      Ron: I’m not sure the amount of Manganese in a “Typical American car” is that significant. Tesla is anything but the “typical American car” and their battery packs are one of the key cost factors influencing current retail costs. If American Manganese produces not only Manganese but the other EMMs (Cobalt, Lithium, etc.) it will have a definite advantage for Tesla vehicles even if it doesn’t hit it’s admirable production target cost.

        Unfortunately I have no idea how much manganese is in a Tesla, or rather, will be. At the moment it may be a lot as they use commercial cells to make their battery packs and manganese dioxide is typically used for the cathode, but I don’t know what type of batteries the new factory will produce. But they definitely could require large amounts of manganese and thank you for pointing that out.
