Less fires should mean more safety for notebook batteries

Matsushita Electric Industrial, best known for its Panasonic brand, announced that one of its battery subsidiaries has established a mass-production system for a lithium-ion battery that incorporates technologies to ensure safety. The company began shipping the industry’s first 2.9 Ah high capacity batteries for notebooks in April this year and is now ready to mass production.

Matsushita representatives said the new design improved battery safety by forming a heat resistance layer (HRL) consisting of an insulating metal oxide on the surface of the electrodes. Lithium-ion batteries contain a thin plastic separator to insulate the cathode from the anode. When a separator is pierced by an electrically conductive material such as a metal particle, a short-circuit develops, causing the battery to overheat and, in the worst case, catch fire. The HRL used in the Panasonic battery, however, has better insulating and heat-resistant characteristics than plastic. Even if a short-circuit occurs, it will cease without causing the battery to overheat.

Prior to HRL, the company adopted stronger separators and thermally stable materials to help guard against battery material contamination. Matsushita said that HRL technology will ease development of lithium-ion batteries to higher levels of capacity and safety.

Following the Sony laptop battery fiasco of 2006, intense interest is paid to the safety of the portable energy source. The IEEE is in the process of updating its standards for laptop batteries, and some companies are starting to use the more stable lithium polymer battery technology.

This is what's good about company developes safer technology based on another's problems. I'd venture to say that their primary motive is to sell more 'safer' batteries. Consumer's safety? A distant 2nd.

Gotta love

Of course.....kind of goes w/o saying....

Be that as it may, it proves that capitalism works.

IT hints that it somewhat worked in this case AFTER a disaster.
Of course isn't it the same capitalism that made sony roll out dodgy accu's because of market pressures?

Sony is working on batteries that use nitroglycerin. That was they can also eliminate anyone who complains about their laptop batteries exploding.

Lol, I was kinda like ??? until I read his whole comment. :P

lmao! Nice one :)

But I think soon it -MAY- be time to forgive Sony for the battery Mc' Crap.

Intel 's flop with the Pentium 4 was forgiven!

And so Was Nvidia's FX series of video cards!

And... ATI's old dodgy drivers!

As opposed to?

I know its not intended like this but my cynical side thinks "and previously they were making batteries that would overheat"?

Yes they were, they decided to take a 'calculated risk' to the public, it happens again and again.
Of course most anything can fail once in a while if you make enough copies, you are bound to have to make certain decisions, but sony apparently also decided to cut on quality checks, but that's another discussion I guess/

I was thinking the exactly same thing...

What a good time to relese none exploding batteries

Now all they need is....

Hydrogen Fuel cell batteries. Fill em up and get maybe.. 18 hours worth of power? The Fuel cell power source for the cell phones were supposed to increase power to 4x or 5x times the life? Did I catch that right?
