Extending three times the amount of batteries of smartphones and tablets by ... sand

Scientists at the University of California and Buorns Technical University (USA) have found a way to triple the battery life of electronic devices, including smartphones and tablets.

The results of this study have just been published in the famous scientific journal Nature Scientific Report. The findings from the University of California and Buorns research teams from the US have been evaluated as a starting point towards the goal of significantly increasing battery life. The team used sand to make an anode instead of graphite. Practitioner Zachary Favors was the one who came up with this idea after he realized in the sand at the beach that contained a lot of quartz.

First Favors collected sand with enough quartz, followed by crushing them into nanometers and refining them. After adding a few other cheap materials like salt and magnesium, the mixture is heated to produce pure silicon. This silicon is very porous, a key factor that improves battery life. The duration of these silicon anode rods is three times longer than that of a standard graphite pole.

The good news is that this solution has relatively low production costs, not to mention that it is non-toxic and environmentally friendly.
