Technology: Battery improvement

Publié le par Jean Arnal

Who has not been angry against low battery load after just few hours activity with their mobile phones or laptops? The problem would be circumvented with new development using silicon nanowires. The promise is a ten-fold increase in lithium-ion (Li-ion) battery operating time. Great! Replacing the carbon anode by silicon nanowires strongly improves Li-ion battery's electrical storage capacity, with limited risk of degradation of performance during time. A patent application has been filed by Stanford University scientists, and they believe that the technology can be pushed to real life quickly.

Another development on the subject has been made by the University of Surrey, using alkaline polymer (rather than acidic polymer) fuel cells. But the research needs work up to 2011.
