Smartphone batteries represent the biggest problem of mobile terminal manufacturers, users asking year after year for terminals with better autonomy, but receiving absolutely nothing in return. In an attempt to solve this problem, a team of university researchers Stanford he thought to be inspired by pomegranates to produce the batteries of future smartphones. The researchers decided to develop new batteries that use silicon to allow a much more efficient storage of energy in batteries, pomegranates being the source of inspiration for designing the internal structure of the battery.
The researchers analyzed how the internal structure of the pomegranates is composed and decided to use silicon nanowires wrapped in carbon shells, this method preventing their swelling after a series of loads. In the image above you have a diagram of the idea that was the basis of this implementation, and the placement of the energy cells in a form similar to the placement of the seeds of a pomegranate allows energy to be stored through many charge/discharge cycles without significantly affecting the structure of the cells.
The use of this new battery structure allows the development of future batteries that will work for longer periods of time even after a large number of charge/discharge cycles, but of course it takes time to perfect the production method.
