Holy Grail of Electric Vehicle Technology? – A Lithium Ion Battery that Charges as Fast as a Supercapacitor

Is this the “Holy Grail” Battery We’ve Been Waiting For?

Nature published a very interesting paper by MIT researchers Byoungwoo Kang & Gerbrand Ceder this week: Battery materials for ultrafast charging and discharging. In it they claim that they have discovered a way to make a lithium iron phosphate (LiFePO4) battery charge and discharge about as fast as a supercapacitor. In practice, this could make plug-in hybrids and electric cars much more practical.

The Nature article states,  “Lithium-ion batteries are commonplace in everything from mobile phones to hybrid vehicles. “They’re essentially devices that move lithium ions between electrodes,” says Ceder. The batteries generate an electric current when lithium ions flow out from a storage electrode, float through an electrolyte, and are chemically bound inside the opposing cathode. To recharge the battery, the process is reversed: lithium ions are ripped from the cathode compound and sent back to be trapped in their anode store.

The speed at which a battery can charge is limited by how fast its electrons and ions can move – particularly through its electrodes. Researchers have boosted these rates by building electrodes from nanoparticle clumps, reshaping their surfaces, and using additives such as carbon. But for most lithium-ion batteries, powering up still takes hours: in part because the lithium ions, once generated, move sluggishly from the cathode material to the electrolyte.”

Here is the abstract of their paper:

The storage of electrical energy at high charge and discharge rate is an important technology in today’s society, and can enable hybrid and plug-in hybrid electric vehicles and provide back-up for wind and solar energy. It is typically believed that in electrochemical systems very high power rates can only be achieved with supercapacitors, which trade high power for low energy density as they only store energy by surface adsorption reactions of charged species on an electrode material. Here we show that batteries which obtain high energy density by storing charge in the bulk of a material can also achieve ultrahigh discharge rates, comparable to those of supercapacitors. We realize this in LiFePO4 (ref. 6), a material with high lithium bulk mobility, by creating a fast ion-conducting surface phase through controlled off-stoichiometry. A rate capability equivalent to full battery discharge in 10–20 s can be achieved.

Put in Perspective: Amount of Space Required to Transport People by Car, Bus, or Bicycle

March 12, 2009 at 5:04 pm

This image below has been going around the internet for quite a while and is quite popular in teh urban planning circles.  Treehugger had a post today and I captured it for you all.  Here is that striking picture from Muenster, Germany.   I am sure you will think twice before you start the car tomorrow..

And That’s Just Space…
They say an image is worth a thousand words. In this case, it really is. You can write about urban planning and air pollution and traffic congestion, but the three photos above show you at a glance the difference between these three means of transportation. And space isn’t everything: Cars also cost more money, pollute more, increase risks of obesity and all kinds of diseases, etc.

Two Updates on the Automotive X-Prize

March 12, 2009 at 3:59 pm

(Source: Autobloggreen)

Autobloggreen article says ” One of the problems for some of the smaller teams that want to win part of the $10 million Automotive X Prize is that they might not have enough funds to get their cars into the streets for the competition. The X Prize team is looking out for them, though, and recently posted a notice about Startup Nation’s 2009 Elevator Pitch Contest that is offering cash to the best ideas to come across the Intertubes. Even if you’re not participating in the AXP, you can still submit a two-minute audio or video file here and tell them why you need X million dollars for your idea. The deadline is March 20. ”     Click here to read the entire article.

 

 

New car CO2 emissions drop dramatically in UK

March 12, 2009 at 3:23 pm

(Source: Autbloggreen


The Autoblogger says “2008 saw the biggest drop ever in CO2 emissions from new vehicles sold in the UK, with a year over year reduction of 4.2 percent. Wtih a fleetwide average of just 158 g/km, cars amount to just 11.5 percent of total UK carbon dioxide emissions. The combination of rapid escalation in fuel prices in 2008 and congestion charges in cities like London undoubtedly pushed many car buyers to some of the low emissions specials like the VW Polo BlueMotion, Smart ForTwo CDi and Ford Fiesta ecoNetic.”

Th!nk details U.S. manufacturing, sales plans: hopes to sell City EV for under $20,000

This morning at the Michigan Information Technology Center in Ann Arbor, Th!nk finally gave the media the details of it’s planned expansion into the U.S. market. The short version: by 2010, Th!nk North America hopes to be building electric vehicles in the U.S. These City models (seen above) will be able to go around 70 mph, pass all required safety standards and be targeted at fleet customers, initially. Th!nk NA will be submitting a loan application to the Department of Energy on March 31, and its U.S. plans are dependent on getting this money. Well, Th!nk officials were hesitant to put a firm number out, but Th!nk CEO Richard Canny said that the price to consumers, after government incentives, would probably be under $20,000, but you’ll need to figure in an $80-90 per month fee to lease the battery.

TH!NK Electric Car Maker Wants to Move to Sweden (or the U.K.)

 Norway’s electric vehicle manufacturer TH!NK has a long and troubled history – gone bankrupt twice, changed hands a couple of times (including a short stormy marriage with Ford) and stopped its production line late last year when the economic crisis hit. But TH!NK’s woes are far from over, it seems, as the company’s leaders try a novel idea: an offer to move TH!NK lock, stock and batteries to a nation willing to prop it up until propserity re-appears. The two current contenders? Battered Britain andSlumping Sweden. Sweden may be in the lead, as Saab has tanked, and Swedish King Carl Gustaf has already reportedly purchased two TH!NK electric vehicles – in blue and gold, of course.

Powercircle says move EV production to Sweden
Sweden’s Powercircle told Miljörapporten it is attempting to broker a deal in which TH!NK would move production to two former Saab sites: Trollhättan near Gothenburg and Uddevalla. Thus a EV manufacturing hub could be created, Powercircle says, with just 185 million Swedish crowns in contribution from the government, creating 500 jobs in the short term.

 After driving the Chevy Volt prototype and sitting down for a number of discussions, the members of the president’s task force on the auto industry have returned to Washington. While the team was in Michiganover the past few days, they had a chance to see GM’s latest technology, look at what Chrysler has brewing, and spent time reviewing the viability plans of the automakers.
Detroit News says  “The administration official would not comment on when the administration might pass judgment on the companies’ restructuring plans or their requests for up to $21 billion in new aid.

“We have been and will continue to work as hard and tirelessly as we can,” the official said. “This is obviously a very substantial undertaking and we want to move with all deliberate haste.”

The group spent most of the day in Detroit, visiting UAW President Ron Gettelfinger and other union officials in the morning before heading to Warren for meetings with GM and Chrysler.

Advisers to the task force visited Chrysler’s Warren truck assembly plant, meeting Chairman and CEO Robert Nardelli and other top executives, the company said in a written statement.

“In addition to meeting, the group toured the assembly plant and reviewed Chrysler current and future products, including electric and hybrid vehicles,” the company said. The meeting also included Chrysler Vice Chairmen Tom LaSorda and Jim Press and Chief Financial Officer Ron Kolka.

AT&T Inc. announced Wednesday that it will spend more than half a billion dollars over the next 10 years on alternative-fuel vehicles.

The Dallas-based telecom giant (NYSE: ATT) will invest $565 million on about 15,000 vehicles over the next decade, including $350 million on 8,000 compressed natural gas vehicles — the largest investment in that vehicle type by an American company in history.

The remaining $215 million will be spent replacing more than 7,000 passenger cars with other fuel-efficient models.

“AT&T and other U.S. corporations have a unique opportunity to partner with the new administration as it works to lead the country out of this economic downturn,” said Randall Stephenson, chairman and chief executive officer of AT&T. “This investment is a first step on our part to help boost other industries while at the same time encouraging wider use and production of efficient vehicles and domestic fuel alternatives.”

Billing it as a way to not only go green but also create infrastructure and jobs in a flagging economy, AT&T said its spending will either create or save about 1,000 jobs each year for the next five years. Both the chassis manufacturing and the conversion to CNG will take place domestically.

Ford builds 100,000th hybrid SUV, bakes a cake

March 10, 2009 at 10:56 pm

 (Source:  Autobloggreen)

Today, Ford celebrates a new milestone in the life of its hybrid SUV platform as the 100,000th vehicle rolls down the assembly line at the Blue Oval’s Assembly Plant in Kansas City. This production total includes all Ford Escape Hybrids, Mercury Mariner Hybrids and Mazda Tribute Hybrids produced since 2004, the year that Ford launched its first ever fuel-saving gas/electric model.

Perhaps now would be a good time to remind our readers that Ford hit the 60,000 hybrid mark in the 4th quarter of 2008, meaning that the automaker’s federal hybrid tax credit will be cut in half beginning in April of this year. Buyers wanting to capitalize on the full rebate will need to make their purchase before the end of this month.
