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.
