The gospel silicon of the drone will multiply the battery capacity

It is well known that batteries are short plates of unmanned systems such as drones. The pursuit of better batteries means the exploration of alternative materials. Scientists believe that silicon has great prospects. a team from clemson university (Clemson University) has proposed a new design that overcomes some of the problems of incorporating this material into lithium-ion batteries and enables the fabrication of a lightweight and high-capacity battery that can be used in various aerospace devices.

 For a long time, scientists have been working hard to study the potential of silicon in lithium ion batteries. replacing graphite as an anode component with this material can increase the storage capacity of these devices by up to 10 times, but some problems need to be solved first.

 in these cases, silicon does not have the same durability as graphite. with the charge and discharge of the battery, silicon easily expands, shrinks and decomposes into small pieces. this leads to deterioration of the anode and failure of the cell, but over the years we have seen many potential solutions, including making silicon into spongy nanofibers or tiny nanospheres before integrating silicon into the device. a new study from clemson university (Clemson University) hopes to enhance the reliability of silicon with the help of carbon nanotubes called Buckypaper. we also found that this carbon nanotube has been used to develop next-generation aircraft thermal shields. The sheets are paired with tiny nano-sized silicon particles, which the team says resemble a deck of cards, sandwiched between layers.

First author of the study Shailendra Chiluwal said :" Independent carbon nanotubes make silicon nanoparticles electrically connected to each other ." "These nanotubes form a quasi-three-dimensional structure, holding silicon nanoparticles together even after 500 cycles and reducing the resistance due to nanoparticle rupture ." The team believes that the advantage of this approach is that even if the charge and discharge of the battery results in the rupture of silicon particles, they will still lock in the sandwich structure and be able to perform its functions. In theory, this means that the functional but experimental battery has a higher capacity, which means that the energy can be stored in a lighter battery, thus reducing the overall weight of the device.

 as a reward, the use of nanotubes creates a buffering mechanism that enables the battery to charge at four times the current iteration speed. But space is a real potential area for the team, funded in part by NASA., and these lightweight, fast-charging high-capacity batteries can be used for a variety of purposes, including electric vehicles According to the study author ," most satellites get energy mainly from the sun ." But when satellites are in the shadow of the earth, they must be able to store energy. We have to make the battery as light as possible, because the heavier the satellite, the higher the mission cost ." Other possibilities, researchers say, include spacesuits and Mars rover power systems. They are now working with industry partners to bring the technology out of the laboratory and into the real world.
