Tesla Motors, a high-tech maker, last month
Announced plans to open the world's largest battery factory in 2017.
The goal is to overcome what it calls the biggest obstacle to meeting the growing demand for its vehicles: a reliable supply of advanced batteries that power it.
To do this, Tesla needs a lot of batterygrade lithium.
The Simbol material came in from here.
Headquartered in Simbo, Pleasanton, California
, Is preparing to break ground at its own commercial plant in August, which will allow it to start production at the same time as the Tesla plant is scheduled to open.
The Simbol plant will be the first to extract lithium from new sources using a unique process: waste from geothermal power plants.
Due to the growing demand for lithium, the demand for lithium is growing rapidly
Ion batteries in electric vehicles, consumer electronics and energy storage.
From 2000 to 2012, total lithium consumption increased by an average of 6.
According to the U. S. Geological Survey, 4% per year.
About 35% of the lithium chemicals sold are used for batteries, and Tesla's plant will almost certainly add that number.
The goal of the automaker is to produce 30 gigawatts.
According to data from Cosmin Laslau, energy storage research analyst at Lux research, the battery capacity in one year exceeded the total global output in 2013.
"When there was rapid growth in 2017 and beyond, supporting another lithium supplier in the market, there was a real inflection point in 2020, which is no better," Josh Green said, he is a general partner of Mohr Davidow, a venture capital firm in Menlo Park, California.
This is the biggest shareholder of Sinbo.
Historically, lithium is mined from hard rock, or condensed into brine by evaporation of a few months of salt water, and then converted into usable forms through chemical processes.
Both production methods are time.
Consumption, messy, relatively expensive.
Since the 2011 incident, Simbol has been at the pilot plant in Khalifa, California.
About 100 metric tons of lithium have been extracted from 49 brine. 9-
Megawatt-grade feather stone geothermal plant in Imperial Valley, California.
Salt water is a mixture of salt and water that can contain different amounts of dissolved solids, including lithium.
After the geothermal plant generates energy, but before injecting the waste salt water into the ground, Simbol uses the hot salt water as a raw material for its chemical process.
"The salt water comes out of the ground, generates electricity, the elements are taken out of the stream, and the salt water goes back to the ground," said Joseph Lowry, vice president of sales and marketing at simbol.
Compared to the traditional lithium production method, the fact of pre-heating salt water reduces the cost and energy footprint, Mr. Lowry said.
Because geothermal companies are exempt from water laws, which allows them to pump salt water back to the ground, the process also avoids Simbol's potential cost of cleaning up or environmental mitigation.
"We don't want this thing to appear on the ground because it will affect the water level," Simbol's chief executive John Burba said since April 2013 . ".
"But this is back where it came from. ”Mr. Burba is a co-
The inventor and chief developer of the basic lithium extraction technology that Simbol is using, he helped develop the technology while working for chemical manufacturers Dow and FMC.
Simbol now has patents and pending applications to improve the filtration process.
Brian Jaskula is a lithium expert at the US Geological Survey in Va Reston.
He said that the process was good.
Confidential Secrets make it difficult to evaluate the technical advantages.
"If it does what they say, it seems promising . "Jaskula said.
To be sure, there are a lot of resources to extract.
Salt water from geothermal plants in Southern California is rich in lithium, as well as manganese, zinc and potassium, according to a water writer who specializes in minerals contracted by Simbol.
Geothermal energy production in the region is expanding. Mr.
Jaskula is optimistic about the opportunity of Simbol, although several other emerging competitors want to start producing lithium as soon as possible and possibly beat Simbol in price, as the company has not yet revealed a breakdown of its production costs.
This is because a stable supply rather than a price is a key factor for battery manufacturersJaskula said.
"Lithium accounts for only 2-3% of the battery content and 2-of the battery price," he said -. ".
"But it's very important that prices are not as important as having a variety of sources to make sure they don't run out.
Simbol said the plant will have the capacity to produce 15,000 metric tons of lithium per year.
The permit is ready, sir.
Burba said Simbol has obtained the water needed to operate the plant
No small feat in dry California
From the Royal Irrigation District, which has reserved water to attract industry.
Mr. Simbol is raising the last 10% of the money needed for plant construction
Burba said he was working hard to complete the project plan and equipment selection.
Simbol will initially produce lithium carbonate and lithium hydroxide, both of which are used for lithium-
Ion cell division.
These products are likely to be sold to lithium battery producers and then to battery producers.
But Tesla's factory is about to go into production.
Bolba said he hopes that Simbo will be ready for supply when the opportunity comes.
