If you don't want to lose your spare lithium batteries for your camera, notebook or cell phone, you might want to pack carefully for your next flight.
New rules from the Transportation and Security Administration that take effect on January 1 ban travelers from carrying loose lithium batteries in checked baggage. Passengers are allowed to pack two spare batteries in their carry-on bag, as long as they're in clear plastic baggies.
Fortunately, you don't have to worry about the batteries that are already installed in the devices you're bringing. The TSA has said it's safe to check in items like a laptop or iPhone that already have the batteries in place.
The agency said that loose lithium batteries not installed in devices pose a fire risk to passenger planes. Recently, the National Transportation Safety Board could not rule out the possibility that lithium batteries started a fire in a plane at the Philadelphia National Airport last year, according to the Associated Press.
If you do plan on bringing spare batteries in your carry-on bag, be aware of some other rules: You can only bring batteries with an equivalent of up to 8 grams of lithium content. (Most batteries for cell phones and laptops meet this requirement.) And for lithium metal batteries, whether carried as a spare or installed in a device, batteries are limited to 2 grams of lithium metal.
As part of its effort to get its first cars out of the door, Tesla Motors is putting its battery business on ice for a bit.

The electric car company back in January said it was going to sell its battery pack--composed of thousands of lithium-ion battery cells--to third party manufacturers. Interim CEO Michael Marks, however, made the decision to suspend the program in September when he also decided to push out the release of the car and scale back production a bit. Although a few Tesla Roadsters may come out this year, the bulk of the first cars will come out next year. Fifty are due in the first quarter. The delays in the battery program, however, were not flagged then.
Tesla's first and so far only announced customer was going to be Think Global, which is trying to come out with an electric town car.
"We delayed the program with Think until we had roadsters on the road," said Darryl Siry, vice president of sales and marketing at Tesla.
As a result, Think has been lining up alternative battery suppliers. A deal with EnerDel was announced yesterday. EnerDel will be the "supplier of choice" for Think.
It is unclear if the switch in battery providers will delay Think's car, but it could. It's a major change. In September, the company told The Norway Post that it wanted to get the initial cars out in November. Think has made cars with other types of batteries--the company grew out of a dying electric car project from Ford. EnerDel won't deliver prototypes until next March and preproduction batteries until July 2008. Still, Think is not aiming to get large numbers out of the factory at first anyway. The company in July, a few months before Tesla changed management, said it only planned to start producing 250 cars a month by mid-2008.
On a happier note for Tesla, it has also started to let customers who have put down deposits on the $98,000 Tesla Roadster take test drives with the latest prototype. They are doing 12 a week and many of the drivers are posting blogs about the experience (see link above). The test drives are taking place in the Skyline Drive and Highway 84 area. You know, the Alice's Restaurant intersection in the Bay Area.
Despite a few nitpicks here and there, the reviews are all fairly positive. (I've ridden in one and they are a lot of fun, particularly the subtle "whoosh" sound the electric engine makes.)
"I've certainly faced some raised eyebrows at my decision to write a check for $100,000 to purchase a car I've never driven, so if nothing else my thrilling test drive of VP10 was worth it just to explain that I have been behind the wheel, and come away impressed," wrote Josh Hannah.
Hannah, though, did get passed by a Subaru Roadster. He wanted to be cautious.
No entries yet from Sergey, Larry, George Clooney or San Francisco Mayor Gavin Newsom yet, who have all allegedly put down deposits.
Phoenix Motorcars, the guys who want to bring you all-electric SUVs and trucks, won't be coming out with their cars this year after all.
CEO Dan Elliot posted this note on the company's site late Thursday night:

(Credit: Phoenix Motorcars)"We must also thank you for your patience in our development progress as we have worked to bring our product to market. We recognize that our product rollout has taken longer than originally expected as we continue to work through certification with the California Air Resources Board (ARB), finalize our financing package, and set up our production facility that will allow us to deliver at the sales volumes we are targeting.
"While Phoenix Motorcars had hoped to begin initial deliveries of its vehicles by this fall, we have decided to delay deliveries until early 2008," the note stated.
Getting cars through the certification process isn't easy and costs a lot of money. Testing--along with the millions of dollars required for design and manufacturing and advertising--is one of the many reasons why you don't see a lot of successful auto start-ups. Tesla Motors is still finalizing testing on its roadster, which it hopes to get out before the end of the year.
Phoenix has more than 500 orders for cars. Pacific Gas and Electric is one customer, Phoenix says. The company has shown its cars at the White House and the Lake Tahoe Summit.
The company's SUVs run on the lithium titanate batteries from Altair Nanotechnologies. The cars are expected to run for about 130 miles on a single charge and hit about 100 miles per hour. The key to the battery, says Altair CEO Alan Gotcher, is that it can be recharged quickly.
The SUVs will first be sold to utility companies and municipalities. These companies buy large fleets of cars and often they don't leave town. Thus, the 100-mile range isn't as big a problem as it is for the consumer market. Later, it will hit up consumers. (Here is an article on Phoenix CNET News.com wrote last year.)
Phoenix is one of a number of companies pumping electric cars. There is also Miles Automotive in Southern California.
General Motors may lease the battery packs for its Chevy Volt electric car to make it more affordable, according to a news report.
The Volt is unveiled at the 2007 Detroit auto show.
(Credit: CNET Networks)GM's electric car will take lithium-ion batteries which are known to be expensive and have a limited lifespan compared with the life of a car.
Bob Lutz, GM's global product chief, has said that the company hopes to make the car available in the $30,000 price range.
While GM has several leading battery technology developers and manufacturers onboard in its effort to build an affordable, long-range rechargeable battery for the car, critics have pointed out that the price point could be a challenge given the technology needed to go into it.
To achieve that price point, GM may rent the battery packs needed to run the Chevy Volt, The Financial Times has reported.
GM announced in early August that the company will be ready to test the Chevy Volt in spring 2008 and is still on track for a late 2010 sales availability.
The lithium ion car battery created by Tesla Motors has passed a battery of certification tests that effectively remove another hurdle in the path toward selling products.
Because they can burst into flames, lithium ion batteries are classified as dangerous goods, according to Erik Toomre, Director of Manufacturing Programs. "Before we ship it to the public, we have to demonstrate that it is safe," he said.
The United Nations has issued specifications on what tests lithium batteries have to pass and these regulations have been adopted and/or tweaked by various governments. In third party tests, both the individual lithium ion cells and the entire battery, which consists of 6,831 cells, passed the UN criteria.
It is something other electric car companies will have to do to.
What's involved? The batteries are deliberately short-circuited and placed on shaking tables. The company also did some puncture testing. Even if one cell blows, the battery pack is designed so that it won't burst into what the lithium ion industry quaintly calls "a runaway thermal reaction." That exploding Dell notebook? That was a runaway reaction.
The entire battery pack weighs about 1,000 pounds, Toomre added.
The company will include the battery packs in its cars as well as ship them to third parties.
Tesla Motors, the guys with the all-electric sports car, have set a goal of manufacturing 800 cars in their first production year.

(Credit: Stefanie Olsen/CNET News.com)The company has already taken deposits for more than 560 2008 Tesla Roadsters, according to a spokesman. The cars sell for $98,000 after a recent price hike from $92,000. If they sell all 800, that will lead to revenue of around $76 million, by my math (average price of 95K x 800).
The company has raised more than $40 million in venture funding.
The Roadster runs on lithium ion batteries and can go from zero to 60 in about 4 seconds. Tesla showed off the car for the first time about a year ago. Since then, it has been building operations. The first cars will go to customers in the Fall. Although some cars will come out this year, these will be considered 2008 models.
The battery in the car is made up of a few thousand conventional lithium ion battery cells. Other electric car companies are looking at batteries from start-ups like A123 Systems, which sometimes employ different battery chemistries.
Altair Nanotechnologies, which specializes in lithium ion batteries, said Monday that it will work with investor AES to develop home energy storage systems that can hold more than 500 kilowatts of energy.
AES, a power company, invested $3 million in Altair earlier this year.

With a big battery in the closet, the energy harvested from solar panels on the roof could be used by a homeowner at night. Home storage also gives utility owners breathing room. Get enough batteries out there and the risk of a brownout goes down.
It can even help utilities put off erecting additional power plants. PG&E says that plug-in hybrids could serve as home energy storage units.
Start-up GridPoint has emerged as an early leader in the field, but it's still relatively small. More companies will jump in.
Altair is trying to play in lots of markets. It also makes lithium ion batteries for plug-in hybrids and claims its batteries can recharge rapidly, a big sticking point for electric cars. Altair also says the batteries are safer than traditional lithium ion batteries.
So far, however, Altair is not producing massive numbers of batteries. At clean tech conferences, the name comes up a lot. But the question everyone asks is, if the technology is so good, how come the company isn't bigger?
Chevy Volt: charging ahead?
(Credit: CNET Networks)When GM unveiled the Chevy Volt at this year's Detroit auto show, it admitted that the electric-powered required a technological breakthrough in battery development for the concept to become a reality. Skeptics suggested that the unveiling was little more than pie in the sky or PR hoopla intended to paint the General in more a more non-electric-car-killing light.
This week, however, GM has gone some way to dispelling that skepticism by awarding contracts to two firms with credentials in the lithium ion battery and automotive industries to come up with a solution to the Volt's power requirements. Compact Power, a subsidiary of LG Chem, and Continental Automotive Systems, a division of Continental A.G, have been tasked with providing lithium batteries for GM's E-Flex range-extender system, the drive train behind the Chevy Volt.
The E-Flex system works by using large lithium ion batteries (charged primarily via a 110-volt AC outlet) to store electricity, which powers the car's electric motor. When the batteries run down, a small onboard internal combustion engine is used to generate more electricity to extend the car's range. To date, however, lithium ion batteries have not been able to meet the power, weight, and durability requirements of such an application. The contracts are not a confirmation that the Volt will be put into production, rather "an opportunity to deeply understand the differing battery technologies before making a production decision," according the GM press release. Still, it's a sign that the Volt might avoid the same fate as GM's EV-1 in the electric-car graveyard.
A123 Systems, the lithium ion battery maker that is working with General Motors and other big wigs, has reportedly bought Hymotion, a company that specializes in converting regular hybrids into plug-ins.
The possible deal was reported by the Web site Clean Break. The companies have not commented, but sources in the plug-in industry say a deal appears to be in the works. If it goes through, it could make retrofitting hybrids into plug-ins cheaper and easier.
Today it costs about $10,000 or more to turn a regular Prius into a plug-in. Plug-ins can be charged through a wall socket and get 100 miles a gallon. At the current prices, it's not an economical choice, according to, among others, Felix Kramer of CalCars, which advocates plug-ins. Going the plug-in route will cut down on greenhouse gas emissions, but an owner would have to drive the car a tens of thousands of miles before the cost of the batteries equaled the gas you would have used.
Only a few small companies offer plug-in conversion services at present, but GM and other car companies are expected to start producing plug-ins at the factory in the coming years. To date, most have been scared away by the additional cost of putting in more batteries. Apparent demand among customers, however, has begun to prompt GM, Nissan and others to get into the market.
A123 also works with major car manufacturers on plug-in hybrids with Cobasys, which comes up with systems for integrating extra lithium ion batteries into plug-in hybrids. (Chevron Ventures is an investor in Cobasys.)
