Antimonene supercapacitors

A team of researchers attached to the group of Nanomaterials and the Sensors and Biosensors of the Autonomous University of Madrid (UAM), with the collaboration of experts in electrochemistry at Manchester Metropolitan University in the United Kingdom, has published a research paper in the journal Advanced Energy Material, where they realize the discovery of a two-dimensional material called antimonide.

This new material is formed by antimony atoms, which are grouped to give rise to a bidimensional material of monatomic thickness.

The antimony is a metal used in the manufacture of semiconductor devices, including infrared detectors and the diodes are. Also combined with lead, it is used in the manufacture of batteries.

The material in question has an extraordinary capacity for the storage of energy and can be used in the manufacture of supercapacitors, according to the opinion of the group of researchers.

It is important to note that super condensers are devices that have the capacity to store large amounts of energy in the form of electrostatic charges, which can be transferred at the time they are required.

The operation of this type of supercapacitors is based on the separation of electrical charges in positive and negative.

Antimonide nanostructure

The antimonide has a nanostructure with a high volume-surface ratio, which is increased by the formation of gaps and channels located between the nanometric sheets.

This condition makes it easier to move and distribute the ions inside the structure, which makes the antimonide an ideal element for the construction of supercapacitors.

It is convenient to point out that supercapacitors are not as popular as batteries and batteries, but it has among its characteristics an extraordinary capacity for storage and energy release quite quickly.

Perspectives on the use of antimonide supercapacitors

The researchers point out that the tests they carried out in order to estimate the storage and energy release capacity of the antimonide yielded extraordinary results.

He proved to be able to store four times more energy than is possible to store with the use of graphene. Additionally, it presents greater stability during the cycles of charging and discharging electrical energy.

This condition makes them ideal for use in electric motors for hybrid vehicles, as an alternative source of electric power for the operation of elevators and highly recommended for hospital centers as an alternative generator when electricity failures occur.

According to the properties of antimonide, it is estimated that it is an excellent candidate for future research regarding energy storage.

For this reason, researchers are studying its use in various applications, one of these is in the development of the sodium battery, which could replace the existing lithium since the latter is a rare material in nature on the contrary of the sodium of which there is much quantity in it.
