A new lithium-sulfur battery could charge your phone for five days

Your electric car could become a mini power station

If technology were to be widely used, it would represent a significant breakthrough in the search for greener and more efficient energy.

The team at Monash University in Melbourne says the lithium-sulfur battery it has created is “the most efficient in the world” and can outperform traditional batteries four times.

Researchers said they were “on the brink” of commercializing innovation and touted its benefits in the fight against climate change.

Most commercial batteries are lithium-ion, but lithium-sulfur alternatives have long been attractive because of their higher energy density and their ability to power objects longer.

However, lithium-sulfur batteries tend to have a much shorter lifespan. They are used in some planes and cars, but previous attempts to bring them to mass production and eliminate lithium-ion batteries have failed.

According to the battery experts at the Faraday Institution, the widespread use of lithium-sulfur batteries is facing “major obstacles” resulting from the “insulating nature” of sulfur and the degradation of the metallic lithium anode.

The team in Australia, whose research was published in the journal Scientists progress, has reconfigured the design of sulfur cathodes so that they are able to withstand higher stress loads without seeing a drop in overall performance.

Their work “will revolutionize the Australian vehicle market and provide all Australians with a cleaner and more reliable energy market,” the lead professor, Professor Mainak Majumder, said in a press release.

The group, whose work has received funding from the Australian government, has patented the new battery and further testing is planned for later this year.

The rapid rise of electric vehicles could lead to a mountain of battery waste

“This approach not only promotes high performance measurements and a long service life, but it is also simple and extremely inexpensive to manufacture, using water-based processes, and can lead to significant reductions in hazardous waste. for the environment, “also said Matthew Hill, who also worked on the team, said.

However, technology presents certain challenges and limitations.
