Title: Lithium batteries could last 20 years Post by: mobaholic on February 08, 2010, 02:55:30 PM If they don't explode ! A JAPANESE OUTFIT has worked out a way to make Lithium batteries that last 20 years. Japanese research and development firm Eamex says that it has come up with technology that will allow batteries to sustain over 10,000 recharges over the course of 20 years. It has managed to do this by using several techniques such as a stabilisation process of the battery's electrodes. This puts less stress on the tin in the battery which, if it is too worried about being unstable fails to make a good bond with the particles to slow down the deterioration process. According to the Kicking Tires blog (http://blogs.cars.com/kickingtires/2010/02/tougher-lithiumion-battery-could-last-20-years.html), the upshot is that you get a battery that lasts up to 10 times longer than most current batteries. Unfortunately Eamex's technology is designed with heavy-duty batteries in mind, such as those used in electric cars. But it is thinking about how to make the things smaller so they can be used in mobiles, laptops and MP3 players.
