Lithium-Ion Batteries Could be Too Expensive, MIT Team Says - buy lithium ion battery

On the surface, the battery
Electric vehicles are ready for prime time.
List of companies planning to introduce new plugins
Hybrid and electric battery cars are long term in the coming years, including General Motors (Volt and a separate plug)
Ford, Toyota, Nissan, Chrysler, Infiniti, aptro, Tesla (Model S sedan), Fisk (Karma plug)
In hybrid), BMW, bright (plug
In mixed commercial vans), Coda, Huige and more.
Almost all of these vehicles will be driven by lithium.
Lithium ion batteries, because lithium has the best available energy density at very low weight.
But a team in the Department of Materials Science and Engineering at MIT, led by Donald Sadoway, I believe there is a problem with lithium for many reasons, it is unlikely that electric vehicles will be widely accepted by consumers.
According to Louis.
Ortiz, research director of the Sadoway Group at MIT, said, "it's all about time frames.
In general, there is a lot of lithium in China and South America, but in order to reach the expansion target, we have to significantly expand the mining speed, and I have not seen the ramp rate that can keep the coal mine up to date with the demand.
Maybe 10 to 15 years from now.
"Another big problem is the cost of lithium," Ortiz said.
"There is no open market for lithium, and demand is very volatile," he said . ". The U. S.
US advanced battery Alliance (USABC) will continue to grow high
Power battery technology that cuts costs to $20 per kilowatt
Extended life to 15 years.
"Such cost and life cycle metrics will make the massive penetration of battery cars an almost predictable conclusion.
But Ortiz saw $20 per kilowatt.
An hour from the future.

Tornadoes threaten more homes to start "the cost has to drop to the point where electric cars can reach the majority of the population," ortiz said: "I think the challenge for lithium is to keep the price of the battery at least twice the price that ABC allows for mass adoption. ".
He added that the containment structure (to ensure safety) and the high achievement of volatile organic carbonated roots used as electrolyte are "fixed excesses" that are difficult to reduce over time ", it's hard to reach $100 to $150 per kilowatt. hour.
Ortiz said the current assessment of lithium is optimistic
Ion Battery Technology $400 to $600 per kilowatthour.
These factors do not inhibit the propagation of the plug.
In hybrid cars, Ortiz says, because they use a much smaller battery pack than a fully electric car.
A recent survey by the University of Michigan of residents of the state shows that there is a general interest in purchasing plugs
Hybrid cars: 46% said they might buy one if the price is $2,500 more expensive than a traditional car.
5,000 of respondents said they would consider buying if they added another $ 30%.
Ortiz's team is working on so-
A class known as "transition metals", including iron, titanium, chromium and manganese, avoids the problem of "hidden resources" because they are easy to mine and are widely distributed.
On last February, Professor Sadoway said to me, "Of course, we can make a lithium --
Ion battery with 200-
Sadoway said, "but it's a problem to be able to make it at the price point of GM or Chrysler.
The whole system must be crash-able, which adds a huge cost to the enterprise.
Professor Sadoway talked about the battery challenge with a class in the video: Sadoway also said, "instead of looking for the most powerful chemical reaction and then considering the cost, I turned the problem around, said, "Let's build a battery based on the elements on the ball --
There is a rich and extensive supply here in the United States.
The cost will be much lower, which means the battery may end up getting so cheap that people won't mind buying a new one every three years.
