New batteries will help explore Mars

The university team decided to create silicon-based batteries that can contain more

charge. They also came up with a structure in which energy is stored in lighter cells. Researchers have long tried to come up with a composition in which, after charging and discharging, the material does not disintegrate into smaller pieces.

The solution that the team came up with isusing tiny nanosized silicon particles that increase stability and provide longer battery life. Instead of several layers of silicon, the battery uses layers of a carbon nanotube called Buckypaper with silicon nanoparticles sandwiched between them.

With such a device, the silicon particles disintegrate, but they do not become less effective, the researchers note.

“Most satellites get their energy from the sun. But satellites must store energy when they are in the shadows. We made the batteries light and capacious, so now this task has become easier "

Using batteries made of silicon and othersnanomaterials not only increases capacity, but also allows them to be charged faster. Fast charging is possible because the new batteries use nanotubes as a buffer mechanism - this makes charging four times faster.

Researchers note that lightweight batteries,which charge faster and are much more efficient can be used not only in devices of the future, but also in space exploration - spacesuits and rovers that will go to Mars.
