World’s Most Efficient Lithium-Sulfur Battery Developed – Powers Smartphone for 5 Days
Monash University researchers have developed the world’s most efficient lithium-sulfur battery, capable of powering a smartphone for five continuous days.
Prototype cells have been developed in Germany. Further testing in cars and solar grids to take place in Australia in 2020.
Researchers have a filed patent on the manufacturing process, and will capture a large share of Australia’s lithium chain.
Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel.”
Monash University researchers are on the brink of commercializing the world’s most efficient lithium-sulfur (Li-S) battery, which could outperform current market leaders by more than four times, and power Australia and other global markets well into 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 lithium-ion products.
The researchers have an approved filed patent (PCT/AU 2019/051239) for their manufacturing process, and prototype cells have been successfully fabricated by German R&D partners Fraunhofer Institute for Material and Beam Technology.
Some of the world’s largest manufacturers of lithium batteries in China and Europe have expressed interest in upscaling production, with further testing to take place in Australia in early 2020.
The study was published in Science Advances today (Saturday, January 4, 2020) — the first research on Li-S batteries to feature in this prestigious international publication.
Professor Mainak Majumder said this development was a breakthrough for Australian industry and could transform the way phones, cars, computers, and solar grids are manufactured in the future.
“Successful fabrication and implementation of Li-S batteries in cars and grids will capture a more significant part of the estimated $213 billion value chain of Australian lithium, and will revolutionize the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market,” Professor Majumder said.
“Our research team has received more than $2.5 million in funding from government and international industry partners to trial this battery technology in cars and grids from this year, which we’re most excited about.”
Using the same materials in standard lithium-ion batteries, researchers reconfigured the design of sulfur cathodes so they could accommodate higher stress loads without a drop in overall capacity or performance.
