No More Exploding lithium-ion batteries?

[Ken_McE]

To make lithium-ion batteries safer, Taiwan's publicly funded Industrial Technology Research Institute (ITRI) developed a new polymer, STOBA (self-terminated oligomers with hyper-branched architecture) to keep them from overheating. The polymer is added to the cathode material inside a lithium-ion battery.

Sounds like good news.

Ok so now it won't explode but the separator is ruined battery disabled lol.

"also extends the life of the li-ion battery by about 20%, or an additional two years"

????

The first link is blank, containing just a blue picture (possibly of the upper atrmosphere) and the second link seems to be nonsense (if it isn't, it's very badly written).

Please explain what this is.

Re: STOBA, a new technology to ensure the safety of lithium-ion batteries

the first page is not blank, but takes a while to load. It's much more understandable than the very poorly written second page, but i'm not sure it contains much more actual information. By twelve sigma I expect they mean a failure rate (probably catastrophic failures rather than all failures inclusively) less than 1.8 per million.

Links are working ok for me.

Re: STOBA, a new technology to ensure the safety of lithium-ion batteries

Both links work fine for me. The website from the second link is located in Taiwan which would explain the bad english. Nevertheless I just found out that somebody already posted about this new technology:

Ah! OK, the 1st link is working now - got it.

I'll merge this with the other thread.

Reuters.com has a brief report on Stoba that loads faster and more reliably:

SAN FRANCISCO (Reuters) - A new technology to prevent lithium-ion batteries from catching fire or exploding in laptops and mobile phones may be on the market as soon as the first quarter of 2010, its inventor said on Wednesday.

The invention, called Stoba, was developed at the Industrial Technology Research Institute (ITRI), Taiwan's national research organization.
When lithium-ion batteries develop internal shorts they can quickly heat up to as much as 500 degrees centigrade (932 degrees Fahrenheit) and catch fire or explode.

Stoba sits between the positive and negative sides of the battery and when the battery hits 130 degrees centigrade (266 degrees Fahrenheit), Stoba transforms from a porous material to a film and shuts down the reaction.

Respecting ITRI, it's definitely not a light-weight:

ITRI has applied for 29 patents in the United States, Taiwan, Korea, China and Japan for Stoba. ITRI holds 9,863 patents and has 5,800 employees, including 1,112 with doctorates. It has created 151 start-ups and spin-offs.
