It also uses the same materials found in a lithium-ion battery, which bodes well for quickly shifting manufacturing over to produce the new design.

The researchers claimed their solution has less of an environmental impact than conventional lithium-ion batteries.

Australian researchers claim they have developed a battery that can keep a smartphone charged for five days or power an electric auto for 1,000 kilometers (over 600 miles).

The new design of the battery has been described as the most efficient ever, so much so that it can keep your phone running for five days on one charge.

An Australian patent has been filed and approved for the new manufacturing process which was inspired by a bridging architecture first recorded in processing detergent powders in the 1970s. Prototype cells for the batteries have been provided by German R&D partners at Fraunhofer Institute. Dr. Mahdokt Shaibani from Monash University's Department of Mechanical and Aerospace Engineering led an global research team to develop the new Li-S battery.

The Monash team reconfigured the design of sulphur cathodes so they can accommodate higher stress loads without a drop in capacity or performance.

Battery manufacturers in Europe and China are interested in upscaling production after further testing, which takes place in Australia this year.

According to lead professor Mainak Majumder, the researchers" work "will revolutionise" the Australian vehicle market and provide the citizens with "cleaner and reliable' energy market. Later in 2020, researchers plan to further trial the battery technology in cars and solar panels.

This Li-S battery would also be cheaper to produce, have a smaller environmental footprint than those now on the market, and lead to less hazardous waste, the researchers say.

That inspiration allowed the creation of a bond between particles that accommodates stress and delivers stability not seen in any battery to date.

The researchers include Dr Mahdokht Shaibani, Dr Meysam Sharifzadeh Mirshekarloo, Dr M.C. Dilusha Cooray, and Professor Mainak Majumder from Monash University; Dr Ruhani Singh, Dr Christopher Easton, Dr Anthony Hollenkamp (CSIRO), and Associate Professor Matthew Hill from CSIRO and Monash University.

"This approach not only promotes high performance measurements and a long service life, but is also simple and extremely low-priced to manufacture, using water-based processes, and can lead to significant reductions in hazardous waste for the environment, "said Hill".
