Batteries Based on Lithium – Sulphur Overcomes the Challenge of Extreme Temperatures

The batteries based on Lithium and sulphur, termed as Li-S batteries have been considered as an excellent alternative to the batteries based on Lithium-ion to electronic power vehicles. The reason for this is their potential to hold up to four times amount of energy as per the unit mass as Li-ion. However, the batteries based on Lithium-sulphur can offer numerous advantages as well as disadvantages and does not only include some problems.

There are numerous applications that can be optimally served with the Lithium-sulphur batteries, like the sulphur present in the electrode can be reduced after just a couple of discharge and charge cycles, or polysulphides can move through the cathode channel and profane the electrolyte.

There is another trouble met with the Lithium-sulfur batteries, and that is the trouble of making sure that they function securely at high temperatures because of their flash temperatures and low boiling temperatures. Now, scientists at the University of Western Ontario, in association with a group from the Canadian Light Source, have influenced a comparatively novel coating technique labeled Molecular Layer Deposition (MLD) that assures to result in durable and safe extreme temperature Lithium – sulfur batteries.

The technique of MLD is necessarily an adaptation of the traditional atomic layer deposition procedures (ALD) that have been utilized to credit thin inorganic based oxide layers. Where MLD advances from its predecessor is the point that it can include organic constituents into the films, making it feasible to generate hybrid inorganic and thin organic layers. The technique of MLD is a proven method for itself that is applicable for utilizing energy storage devices. It even offers a huge volume of control over a thick layer and the chemical composition of the specifically targeted material at a small, molecular scale.

The research has been demonstrated by the scientists in a magazine. These researchers are from Canada and have been able to fabricate secure, extreme temperature Lithium sulfur batteries on widespread electrodes based on carbon-sulfur with the use of an MLD alucone layer. “We validated that the technique of MLD alucone layer provides a secure and versatile method towards the lithium – sulfur batteries at a greatly elevated temperature,” says Andy Xueliang Sun, who headed the entire research at the University of Western Ontario. The experts are considering this as a result that is useful and adequate to cater various applications.

In this experimental study, it has been demonstrated specifically by the scientists that the MLD alucone layered electrodes based on carbon-sulphur settled to their position and remained stable and even displayed boosted and enhanced performance at high temperatures. The temperatures were maintained to as extreme level as 55 Degree Celsius. Also, it is expected by the researchers that the figures of performance must significantly enhance the battery life for extreme temperature Lithium Sulphur batteries. Now, since such batteries have been designed that can optimally serve various rigid applications, there are now possibilities that better results and adequate end results can be obtained.
