      The World's Most Efficient Lithium-sulfur Battery is about to Be Commercialized

The battery is like a stone blocked under the "wheel of scientific and technological progress". It can be said without exaggeration that the day when the battery performance problem is solved is the day when the technology product changes greatly: Imagine if there is such a battery, it can be used for How comfortable your life will be if your phone is powered continuously for 5 days, or you can run an electric car for 1,000 kilometers without charging (it should be like this, isn't it?).

Dr. Madotta Shebani, Department of Mechanical and Aerospace Engineering, Monash University, led an international research group to develop an ultra-high-capacity "lithium-sulfur battery" that is better than the lithium-ion batteries currently on the market The performance of the battery is more than four times higher, which not only has better performance, but also has less impact on the environment. The better news is that this battery is about to be commercialized, storing electricity for consumers in the Australian and global markets.

Researchers have adopted a new "sulfur cathode" design on the basis of standard lithium-ion batteries, so that the battery can withstand higher voltage loads without reducing the overall capacity or performance of the battery. The design was inspired by a unique bridge structure design that was first seen in the washing powder processing process in 197X. The team adopted a method that can establish a voltage-adaptive chemical bond between the particles inside the battery, thereby creating a battery that has never been seen before. The stability.

Associate Professor Matthew Hill said: "This method not only improves the performance of the battery and prolongs the service life of the battery, but also the manufacturing process is simple and the cost is low; because the water-based process is used, the manufacturing process is significantly reduced. Toxic waste. "

The research team has applied for a patent for the manufacturing process, the patent number is PCT / AU 2019/051239, and the German partner Fraunhofer Institute for Materials and Optical Technology has successfully manufactured a prototype battery.

The attractive performance, low manufacturing cost, sufficient raw material supply, easy processing and good environmental impact make this new type of battery extremely attractive. This is a breakthrough for the Australian industry and is likely to change the way of production of mobile phones, cars, computers and solar power grids in the future. Some of the world's largest lithium battery manufacturers in China and Europe have shown deep interest and will be in (Years) for further testing in Australia.

Professor Mayak Magimed said: "The manufacture and application of new lithium-sulfur batteries will occupy a significant part of Australia's $ 213 billion 'lithium industry' and revolutionize the Australian automotive industry to provide cleaner Australians Reliable energy market. The research team has received over $ 2.5 million in funding from government and international partners, and this year we will start trials of this latest battery from electric vehicles and the grid.
