MIT chips away at lithium ion barrier

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.

Apple Snow Leopard plus Nvidia equals what?

Nvidia is in at Apple. So, what's the connection between Apple's graphics-fortified lineup and Snow Leopard OS X?

First a quick canvass of the state of Apple's graphics. Low-performance Intel integrated graphics have been booted from MacBooks, replaced by Nvidia. And, earlier this week, Apple updated the iMac, Mac mini, and Mac Pro with Nvidia graphics across the board and didn't mince words on its Web site: "Ultrafast Nvidia graphics" ad copy is prominently displayed for the iMacs. ATI graphics are also promoted for the Mac Pro and offered on the iMac.

Then, there'… Read more

Nvidia chips score big in Apple Mac lineup

Updated at 11:50 a.m. PST with additional information on Nvidia and ATI graphics in Mac Pro

Apple's rollout of new Macs Tuesday was a vote of confidence for Nvidia: its graphics chip have now become as ubiquitous as Intel's processors across the Mac line.

Apple's entire Mac lineup now features Nvidia GeForce GPUs. "If you go into a retail store, it's (Nvidia) top to bottom," said an Nvidia spokesperson today. "The message is that Apple is differentiating itself, investing in the GPU," he said.

The GPU, or graphics processing unit, … Read more

'BusinessWeek' ponders lithium ion market war

"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

Rinspeed to debut transforming electric concept car

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

Nvidia aims at top Netbooks, Windows 7

Nvidia is working with top-10 PC makers to bring its graphics chips for the first time to Netbooks, according to an executive at the company. And an important part of this push is getting its silicon working with Windows 7, a more Netbook-friendly operating system than Vista.

This week, Nvidia released Windows 7 beta drivers for the "Ion" Netbook silicon that it's handing over to customers. In conjunction, Nvidia demonstrated in Taiwan this week applications running on Windows 7. Nvidia also announced that its Ion platform has been certified on Windows Vista.

The Ion chipset is based … Read more

Nvidia in, Intel out for Apple Mac Mini?

Is Nvidia elbowing out Intel at Apple again? Will the same Nvidia GeForce 9400M chip that caused a small sensation when it dislodged Intel graphics silicon in the MacBook line land in the Mac Mini too?

Tom's Hardware is speculating that it's Nvidia's Ion platform that is Mini-bound.

But Nvidia's Ion chipset is tied strictly to Intel's Atom processor. It seems unlikely that Apple would demote the Core 2 Duo-based Mini to the slower Atom chip. Though anything is possible with Apple, it seems more likely that Apple will upgrade the ancient Intel GMA 950 … Read more

Battery maker Boston-Power fills coffers to expand

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

GM to build Chevy Volt batteries

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

Ion's bevy of turntables and iPod accessories

Vinyl may be a dead music format, but that's not stopping Ion from doing a brisk business with turntable sales. It may sound crazy, but Ion's found a nice, little niche with its affordable turntables made specifically for converting your dusty record crates into iPod-ready MP3 files.

Ion also does well with its unique iPod accessories. For 2009, it is planning a mini version of the Block Rocker iPod amp called the TailGater, as well as a wireless iPod speaker system, a portable iPod audio recorder, and some wireless digital DJ gear. Browse our slide show for more … Read more
