Breakthrough Could Double the Battery Life of Your Next Tablet

by Reads (2,456)

Nothing is worse than being in a situation where you’re on the go and all of a sudden realize that your tablet or phone is about to die, and you aren’t able to recharge. Good news could be on the horizon, however, as a new breakthrough in battery technology could greatly extend the battery life of virtually every kind of mobile device.

Researchers at the Materials and Surface Science Institute (MSSI) at the University of Limerick in Ireland say they have developed a new technology that more than doubles the capacity of a lithium-ion battery. Even better, it will retain the high capacity even after the battery has been charged and discharged over 1,000 times.

Just a Bit Technical

The technology is based on a germanium nanowire-based anode. Traditional lithium-ion batteries are based on graphite, which has a low capacity. Researchers have used nano-technology to restructure the germanium with nanowires to create a substance with higher capacity that remains stable over long periods of time, despite continued use.

According to the researchers, this new technology is highly scalable, inexpensive, and requires very little energy to produce.

Dr. Kevin Ryan, the head of this project, said “This breakthrough is important for mobile computing and telecoms but also for the emerging electric vehicle market allowing for smaller and lighter batteries that can hold more charge for longer and maintain this performance over the lifetime of the product.”
