Introduced the world's most efficient lithium-sulfur battery

Researchers from Monash University, Australia, developed the world's most efficient lithium-sulfur battery known so far. Imagine having a power source that has the potential to power your smartphone for five days in a row, or to allow an electric vehicle to drive more than 1,000 km without stopping to supply you with recharge. Those are some of the possible applications and benefits offered by this interesting launch, of which we will review some background.

Monash University researchers are on the verge of commercially launching the world's most efficient lithium-sulfur (Li-S) battery, which could outperform current market leaders with up to four times the performance, powering by the way to Australia and other global markets in the future.

Dr. Mahdokht Shaibani, from Monash University's Department of Mechanical and Aerospace Engineering, led an international research team that developed an ultra-high-capacity Li-S battery that has better performance and less environmental impact than current products. lithium ion.

The researchers have an approved registered patent for their manufacturing process. Its prototype cells have been successfully manufactured by the German R&D (Research and Development) partners of the Fraunhofer Institute for Material and Beam Technology.

Following the publication of this discovery, some of the largest lithium battery manufacturers in China and Europe have expressed interest in participating in the increased production of these specimens, which is why more tests are planned to be carried out in Australia during the initial 2020 season.

In discussions with Techxplore, Professor Mainak Majumder said this development marks a breakthrough for Australian industry as it could transform the way phones, cars, computers and solar networks are manufactured in the future.

The successful manufacturing and deployment of Li-S batteries in automobiles and networks will capture a more significant part of the estimated value chain of $ 213 billion of Australian lithium. This will revolutionize the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market, Professor Majumder noted.

Our research team has received more than $ 2.5 million in funds from industry partners at the government and international levels to test this battery technology in automobiles and networks this year, which we are most excited about, he added.

How did this discovery come about?

The Monash researchers began their tests using the same materials used to make standard lithium-ion batteries. They reconfigured the design of sulfur cathodes so that they could accommodate higher voltage loads, without generating losses in capacity or overall performance.

The inspiration originated from a unique bridge architecture, first recorded in detergent powder processing in the 1970s. The team designed a method that created interparticle bonds that offered a level of stability that had not been seen before. no batteries to date.

According to Associate Professor Matthew Hill, this attractive design involves lower manufacturing costs, has abundant supplies of materials, is easy to process, and has less environmental impact. These qualities make this new battery design attractive for specific future applications.

This approach not only favors high performance metrics and long cycle life, it is also simple and very low cost to manufacture, using water-based processes, and can lead to significant reductions in environmentally hazardous waste. environment.

Considering the number of devices that use these batteries today to enjoy autonomy and the good capacity that lithium has had as an alternative to manufacture them, this announcement presents a powerful alternative.

The academic report after this discovery was published in early January of this year and can be found on the web.
