When It Comes to Car Batteries, Moore’s Law Does Not Compute - lithium air battery

Silicon Valley may be the center of the emerging electric vehicle industry, but don't expect the battery revolution to mimic the computer revolution, which is one of my ideas. B. M.
Energy storage scientists suggest.
Forget the law of Morey-
My senior manager, Winfried Wilk, said it's not like that at all. B. M.
Referring to the motto put forward by Intel founder Gordon Moore, the computer processing power of the Intel Battery 500 project is about double every two years.
Lithium ion is clearly the best battery technology of the day, and it has been flat and completely flat since 2003
Wilcke said at a party in San Francisco last week that executives from I attended the meeting. B. M.
Better Place, an electric vehicle infrastructure company in Silicon Valley. Mr.
Wilcke discovery team at I Almaden Research CenterB. M.
San Jose, California
, Is trying to develop a new battery technology called lithium air, which allows cars to drive 500 miles on a single charge.
Most of the electric vehicles listed this year travel about 100 miles.
This battery can theoretically be packed 10 times the energy density of the lithium ion batteries used in electric vehicles today, because they use air sucked from the outside of the battery as reactants.
That means lithium.
The weight of air storage equipment is less than lithium-
Ion batteries, which is also a factor in improving the performance of electric vehicles.
I always compare it to climbing Mount Everest. Wilcke said.
We have just left base camp in the last two months.
This means that we have actually made some major breakthroughs.
He declined to give details, but said his team had shown lithium-
The air battery can be charged, something that has not been done before.
If there is one, it will take many years to be useful, he said.
This is a very high-high-risk project.
He talks about the challenge of building a battery with the energy density of gasoline, and it takes 47 seconds to invest 13 seconds.
When he stopped on his way to San Francisco to refuel, there were 6 gallons of gas in the car.
This will provide electricity at a speed of 36,000 KW, he said.
During this period, an electric car needs to pump 6,000 KW to charge the battery.
Our dream today is to charge the same car in a few minutes and drive away hundreds of miles, which is impossible, SirWilcke said.
Not for at least 50 years. âx80x9dMr.
Wilcke and Lawrence Seve, head of the global alliance, denied the idea of rapid growth.
Charging stations that are being tested in California and elsewhere have solved the battery problem.
Depending on the battery, high
The voltage station can charge the battery to 80% capacity in 20 to 30 minutes instead of charging 8 to 10 hours with a more traditional charging station. I'm Alan Shure. B. M.
The vice president of strategy, energy and utilities noted that the cost of inserting a fast charging station could be prohibitive given the equipment's requirements for the grid.
There is a physical possibility of a fast
Charging mechanism and fast
Charging socket, but can the power network support? âx80x9d Mr. Seeff said.
What do we define with fast? charging?
Is it 20 minutes, 10 minutes, 30 minutes?
Because if you have two people waiting to fast
Charge, you may have to wait an hour.
The business model for better places is based on the deployment of traditional charging stations in urban areas, as well as the construction of stations where drivers can trade in batteries for new ones if they need longer. In the end, Mr.
A breakthrough in batteries and electric vehicles could happen elsewhere, Wilcke said.
What do we do in America? S.
That is not important, he said.
What is important is what China has done.
The Chinese government has a goal that 50% of all new cars sold in China will be batteries by 2020 --powered.
This will change the game.
