Scientists at the Massachusetts Institute of Technology have demonstrated how a genetically modified virus can be used to construct both the cathode and anode of a lithium ion battery.

Virus-built rechargeable batteries would have the same power capacity as the batteries used to power hybrid cars, project leader professor Angela Belcher said in an MIT press statement on Thursday.

In a paper published in the journal Science, the research team explained that it manipulated two genes of the M13 virus to equip the bacteriophage with peptide groups that attract single-walled carbon nanotubes at one end, while the other end of … Read more

Hewlett Packard on Monday said that its long-lasting Enviro laptop batteries from Boston Power are available with a three-year warranty.

The batteries costs $149.99 and fit 18 of HP's laptops. They can be purchased online now and will be available in stories later this month.

HP has branded Boston Power's Sonata batteries under the Enviro name to emphasize the environmental attributes. With a longer-lasting battery, consumers need to upgrade less often, which reduces the number of batteries that need to be recycled, HP said in a statement.

Last year, an HP representative estimated the Enviro line costs … Read more

Engineers at MIT have made a breakthrough that could translate into smaller, lighter, and faster-charging lithium ion batteries, the Massachusetts Institute of Technology announced Wednesday.

Gerbrand Ceder, the Richard P. Simmons Professor of Materials Science and Engineering at MIT; aided by Byoungwoo Kang, a graduate student in materials science and engineering, have made a small battery that can be fully charged or discharged in 10 to 20 seconds.

A detailed explanation on how they did this has been published in the March 12 issue of Nature, but here is a brief recap of what they essentially accomplished.

While lithium ion … Read more

"Should Uncle Sam provide billions in loans and grants to a promising but unproven business? Or should the government wait for the market to sort things out before it backs a U.S. company?"

Those are questions posed in a BusinessWeek article last week. However, the questions are largely rhetorical: the U.S. Department of Energy already has a $25 billion Advanced Technology Vehicles Manufacturing Loan Program, and many car and battery companies are counting on these loans to aid their development and production of lithium ion batteries.

So it's not a question of "should," it's a question of "how?"

Lithium ion batteries will add at least $8,000 to the price of a production plug-in hybrid vehicle, according to BusinessWeek. However, that amount is probably on the low side when you consider that the Chevy Volt is predicted to cost a bit less than $40,000, a good portion of that price being the battery. Another manufacturer representative estimated that a lithium ion battery currently costs approximately $22,000, effectively putting the electric car out of reach to all but the well-heeled greenies. … Read more

Swiss automaker Rinspeed will debut at the 2009 Geneva auto show an electric concept car that changes shape to conform to the number of passengers on board.

The iChange is a lightweight, 4,280mm (approximately 14 feet) EV sports car with a teardrop-like silhouette designed to maximize fuel efficiency for the single passenger. But with the push of a button, the sloped rear of the car pops up to accommodate two additional passengers, if needed.

The concept sports car forgoes doors, opting for a very ADA-unfriendly clamshell roof. Rinspeed is obviously assuming that in the future, women will no longer wear skirts. … Read more

I suppose most of the excitement from MacWorld Expo has died down by now, but I'd still like to talk a little about two new Mac laptops introduced at the show-- Apple's own 17" MacBook Pro, and Axiotron's Modbook Pro, a tablet computer made by repackaging the components from Apple's 15" MacBook Pro along with some new parts.

First, the Axiotron product. Externally, the ModBook Pro is radically different from the Apple notebook that provides most of its component parts.

In this publicity photo, the Modbook Pro's beveled edges are apparent. The shape … Read more

Laptop battery maker Boston-Power on Wednesday said it has raised $55 million to expand its manufacturing, and develop lithium ion batteries for transportation and potentially other applications.

The Series D round was led by Foundation Asset Management, the investment arm of a Swedish foundation, along with existing investors Oak Investment Partners, Venrock, GGV Capital, and Gabriel Venture Partners. Altogether, 4-year old Boston-Power has raised $125 million.

Boston-Power's first product a long-lasting battery called Sonata, is available for Hewlett-Packard laptops. While the run time of current laptop batteries starts to degrade after about 150 charges, the Sonata can go for … Read more

General Motors has decided to manufacture its own battery packs for its new electric vehicle, the Chevy Volt.

"GM is getting back in the battery business," CEO Rick Wagoner announced Monday.

The company also announced Monday that it has chosen LG Chem to provide the lithium-ion cells for the battery packs GM plans to manufacture.

GM announced in September that it had chosen a battery supplier, but would not reveal which company that was. LG Chem and A123Systems have long been involved in the development of the lithium-ion cells for the Volt's E-Flex electric drive train. While … Read more
