Updated November 20, 2018 03:08:15 A device called Sulfura Electronico is currently under development at the MIT-affiliated Nanoscale Nanoscopy Institute (NNI) and will soon be ready for the market.
The device is made of a carbon-based alloy that can be used as an energy storage device.
The team is also working on a way to make the material use a different form of electron transport called a “sulfury electron” to improve its efficiency and decrease its cost.
The nanoscale alloy could be a boon for batteries, energy storage, and solar-powered energy systems.
The technology is being developed as a component for a new kind of energy storage battery, called a S/S (sulfurous) electrolyte.
In its current state, S/s electrolytes use an electric current that drives a lithium-ion battery, but S/synthetic materials have been demonstrated to store a wide range of electrical charges, such as carbon dioxide and hydrogen, in a variety of configurations.
“Sulfur, like a metal, is an incredibly strong material, and the carbon-containing element in this alloy could prove particularly well suited for the construction of battery-like devices,” says Nanoscience Professor Rami Iqbal, who led the team.
Iqbals team is currently working on the fabrication of a silicon-based material with a unique chemical structure called “silicon-boron-based carbon-carbon-based sulfide”.
The materials are designed to store energy using a sulfur-rich environment, similar to how batteries use sulfur as a charging source.
In contrast, the S/silicon compound can store carbon dioxide in a sulfuric environment, which could have applications in energy storage.
“Silicon-based compounds have the potential to be an alternative to the use of carbon-centric electrode materials for storing energy,” Iqbahs said.
Sulfury electrons are a fundamental component of a number of semiconductor materials.
For example, graphene, the strongest known material, can be made from sulfur atoms.
But sulfur-containing compounds like Sulfuras metal oxide have also been demonstrated.
For instance, Sulfuran is used in the solar cells of the Samsung Galaxy Note 8 smartphone.
S/Synthetic carbon-sulfure metals have also recently been developed for energy storage applications, including in a solar cell called S/C-SiO 2 that uses sulfur in the metal’s anode.
The S/carbon-sulphur composite could have other applications, as well.
“If the materials can be combined with other types of materials that we can think of, we might be able to do things like storing energy in materials that are much cheaper than traditional batteries,” Iqubahs says.
“It might be the ultimate use of this material for energy-storage batteries.”
Sulfurable electrodes are ideal for storing electricity as they are a very strong, flexible material that can withstand extreme temperature extremes.
“They are very efficient, and their electrical properties are very good for their density, which means that they can store much more electricity than conventional batteries,” says Iqbaas.
“The carbon-dioxide electrolyte, on the other hand, is much more expensive, and has a much higher energy density, but has a lower electrical density, so it is also much more prone to degradation.”
The team hopes to use the Sulfure compound to improve the performance of existing batteries, as it can be a better conductor of electricity than lithium ion batteries.
“A battery is essentially a piece of carbon material with electrons that are trapped inside, and if you want to be able it to charge and discharge efficiently, you have to store electricity in a conductor that is a much better conductor,” Iqs said.
“With this compound, we can build an electrode that is very strong and can store energy in a very stable form, which is a big benefit for batteries.”
Iqbas is optimistic about the S/-S alloy being a significant component of batteries.
The material is stable and efficient at low temperatures, and it can store electricity at very low temperatures.
“I think it will be a big deal to see S/siurate as a substitute for the battery,” he said.
In fact, Iqabas is working on ways to make S/Siurate more efficient and lighter, which would allow the battery to be much smaller, much faster, and much more efficient.
He hopes to find ways to combine S/solids with other metals and catalysts to make new S/suvurates, which will allow the batteries to store more electricity.
Iqs’ group is currently studying ways to increase the efficiency of sulfur batteries by using a “carbon-doping” process that could increase the energy density of the batteries. Iqi’s
