New Lithium Batteries from Sony

Posted by Chris Gohlke in "Digital Home Hardware & Accessories" @ 03:30 PM

http://www.sony.net/SonyInfo/News/P...083E/index.html

"Sony Corporation today announced that it has launched a new type of lithium ion secondary battery that combines high-power and long-life performance, using olivine-type lithium iron phosphate as the cathode material. Shipment commenced in June 2009. The Olivine-type lithium iron phosphate used in this new battery is extremely suited for use as a cathode material due to its robust crystal structure and stable performance, even at high temperatures. By combining this new cathode material with Sony's proprietary particle design technology that minimizes electrical resistance to deliver high power output, and also leveraging the cell structure design technology Sony accrued developing its current "Fortelion series" lithium ion secondary battery line-up, Sony has realized a high power density of 1800W/kg and extended life span of approximately 2,000 charge-discharge cycles."

From the full press release, it sounds like this technology will first be showing up in batteries for cordless power tools and other similar applications. But, expect to see it migrate to other mobile devices soon.

Better Batteries: The Next Generation of Lithium-Ion Technology From Boston Power

Posted by Jason Dunn in "Digital Home Events" @ 04:02 PM

The first presentation I attended at CNTRSTG was by Boston Power, a battery company that's been making some waves lately with probably the most significant enhancement to Lithium Ion batteries that we've seen in several years. Given how little Lithium Ion batteries have changed in the past decade, that's not exactly hard to do, but Boston Power is definitely moving the needle.

Dr. Christine Lampe-Önnerud, the founder of Boston Power in 2005, is a scientist by training and was part of a team of 20 people who pioneered lithium ion technology in the 1990s. She studied at MIT, and worked at Bell Labs; she knows batteries. Her team at Boston Power has over 300 years of combined experience in Lithium Ion batteries.

There are two main problems with Lithium Ion batteries today: poor long-term performance and the fact that batteries just don't power our devices long enough to make us happy. Although the examples that Lampe-Önnerud brought up seemed unrealistic in my experience - she mentioned serious battery performance loss in the first three months - it's true that over the long term battery performance gets increasingly worse. I tend to use my laptops in fairly controlled environments, but if someone is routinely using (or leaving) their laptop in extremely hot or cold environments the viability of the battery will definitely be impacted. You might get four hours of battery life on your laptop when you first get it, then six months later you're only getting three hours of run time. This is what Boston Power is trying to change.

Power Woes: It Shouldn't Be This Difficult

Posted by Jason Dunn in "Digital Home Talk" @ 10:00 AM


All our gizmos and gadgets need power, and for the most part I only get grumpy about power issues when it's time to go away on a business or personal trip. This time, it was our two-week vacation in Japan, and I was extra grumpy about power. Why you might ask? I called Air Canada two weeks before our trip and was informed that the plane we were flying on had no power plugs for laptops in economy class - it seems like every long-haul plane in the world has power except for Air Canada's.

Normally that wouldn't have bothered me because I've been rather fortunate when it comes to laptop power: for nearly two years I used a Fujitsu P7010 laptop, one that I could remove the DVD drive on and insert a second battery to get a solid 10 hours of power. To get even more juice on the go, I tried out a Valence N-Charge that gave me a huge battery boost - can you imagine 20 hours of laptop battery life? I was living the dream. I also had a Proporta laptop battery that gave me less in terms of extended power, but was much more portable. I was completely covered...until I got a new laptop: the Dell XPS M1330.

The M1330 is an impressive laptop, balancing portability with punch - I got mine last September, decked out with the best Dell had to offer: 2.2 Ghz Core 2 Duo processor, 200 GB 7200 hard drive, 4 GB RAM, and the NVIDIA GPU. It's fast, it chugs through RAW photo files like the bad mother that it is, and I'm generally quite pleased with it - until it runs out of power. Sure, I got it with the biggest battery possible (a 9 cell), and I've gotten used to the "hump", but after about four hours, the laptop is dead. Here's where I get frustrated: the Proporta battery, which I was so enthusiastic about when I had a laptop that worked with it, doesn't work with the Dell. At first I thought it was the lack of an adaptor (the M1330 uses this bizarre six-sided plug), but I eventually found one of the plugs that fit - yet even switching the Proporta battery between both voltage modes, it wouldn't power the XPS M1330. Damn. Read more...

Batteries Causing Screen Cracks?

Posted by Darius Wey in "Zune Talk" @ 01:00 PM

http://www.engadget.com/2007/01/31/zune-screens-cracking-from-battery-pressure/

"Interesting news on the Zune front: a friendly tipster's buddy works at a Microsoft call center and handles Zune-related issues. Apparently they've received numerous reports of the Zune screen cracking for no apparent reason, after being left charging overnight. Our tipster's friend conjectures that the lithium ion battery -- which resides right behind the top half of the Zune's screen -- is expanding from overheating and putting too much pressure on the screen, causing it to crack. Unfortunately, Microsoft currently regards the issue as outside warranty coverage, leaving the victims with a broken Zune and nowhere to turn.

A quick skim of the Engadget comments sees many Zune users leaving their devices charging overnight with no problems whatsoever, so it's tempting to tag this whole story as "nasty rumour slash scam". Although, if you're one of the few who have reported cracking screens to Microsoft, we'd sure like to hear from you.
