Researchers from Monash University in Australia announced the development of a new battery they say is the most efficient sulfur lithium battery in the world, and according to the university, the Li-S battery is capable of operating the smartphone for five consecutive days, and it also allows the electric car to travel more than a thousand kilometers without The need to ship it.
The research team resolved a major impediment to the commercial manufacture of lithium sulfur batteries, and, according to details published earlier, researchers redesigned sulfur cathodes to accommodate high stress loads without decreasing capacitance or overall performance, using the same materials used in standard lithium-ion batteries.
Sulfur lithium batteries offer four times the current energy storage efficiency based on lithium-ion technology.
The researchers said: The polymer binding material used in the manufacture of sulfur cathodes was evaluated on the basis of its ability to make dense, microscopic structures free from cracks, and we showed a simple method to produce a cathodic structure that provides minimal interference with electrochemical reactions and ions movement and can expand to expand the natural volume during discharge, thus This results in significantly higher performance metrics.
The research paper indicated that the team designed a method that created bonds between molecules to absorb stress and provide an unprecedented level of stability.
The team noted that the prototype cells had been successfully manufactured by the German Fraunhofer Institute, to be tested in Australia early this year in cars and the electrical network.
According to a participant in the development process, the battery performance along with lower manufacturing costs, abundance of materials, ease of processing and reduced environmental footprint make its design attractive to future real-world applications.
It is noteworthy that this approach not only supports high performance metrics and long cycle life, but is also simple and low cost to manufacture, using water based processes, and can lead to significant reductions in environmentally hazardous waste.
