The batteries, unfortunately, have not evolved at the same pace as the rest of the components of our smartphones. However, several investigations have been made to improve them. The latest uses nanomaterials chains to accommodate more lithium ions.
This research work was conducted by the University of Purdue (Indiana, USA) and now the next step is to apply the technology created on a battery the size of those we use on our smartphones.
The construction and materials used in the lithium–ion batteries we use daily have not evolved to the pace that would be expected. There are several investigations carried out in this area, but few can bring improvements to a final product that is profitable to put on the market.
Most of them are related to the use of new materials for the flow of lithium ions that are the basis of the power supply. Currently, the standard material is graphite, but this group at Purdue University resorted to a chain of nanomaterials that brought considerable improvements to the process.
The choice of graphite is especially due to its price and its characteristics, which, for the moment, is the main material used by the industry. However, this may change soon.
This research team, instead of using graphite that is common, resorted to antimony in a nanochain for storing the lithium-ion battery.
Compared to graphite electrodes, this antimony structure achieves twice the capacity of lithium ions. Also, this effect was seen in a long-term perspective, as the capacity remained for 100 cycles of loading and unloading.
Besides, one of the advantages present in this method developed by the team of researchers is in your safety. Several other materials have already been tested, but there is the risk of the battery expanding or even exploding. However, this was not registered with the use of antimony nanochain.
Thus, this team of researchers has managed to develop a safer and more advanced manufacturing method. It is expected that with this innovation, the smartphone battery lasts longer and degrade less. Scientists will continue their work in this area, and the next goal is to apply this technology to small batteries, like the ones we have on our smartphones.
