A mobile phone battery that recharges in 60 seconds

Researchers at Stanford University in California have built a mobile phone battery that can be recharged in less than a minute.

Their prototype uses aluminium as a substitute for lithium cells.

“[The battery] has a reasonable capacity and a very long cycle life. It has no decay over hundreds of cycles, even thousands of cycles,” said Stanford graduate student Ming Dong.

There is one downside, however, as the battery only carries half the voltage of current batteries.
