New battery could power a smartphone for 5 days

The study, published in the Science Advances journal on Saturday, January 4, 2020, is the first-ever Li-S battery research to appear in this prominent worldwide publication. Soon, lithium-sulfur batteries could possibly takeover lithium-ion batteries as the industry standard.

But lithium-sulphur batteries lose their charging capacity drastically over charging and discharging cyclea, due to an increase in volume of the electrode, causing it to fall apart.

Researchers at Melbourne, Australia's Monash University have announced the development of what they claim is "the world's most efficient lithium-sulphur battery".

Professors Mahdokht Shaibani, Mainak Majumder, and Matthew Hill describe their patented manufacturing process and research in a paper published recently in the journal Science Advances.

Dr Mahdokht Shaibani from the Department of Mechanical and Aerospace Engineering of Monash University headed an global team of researchers that created a novel Li-S battery that has an ultra-high capacity, more improved performance, and minimal environmental impact when compared to existing lithium-ion products.

The new manufacturing process devised by Dr Shaibani's team - which includes reaserchers from Monash University, CSIRO, University of Liege and Germany's Fraunhofer Institute for Material and Beam Technology - solves the electrode expansion issue. On the other hand, the team in Australia have reconfigured the design of sulphur cathodes so that they are able to withstand higher stress loads without declining the overall performance.

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".

Some of the largest makers of lithium batteries in China and Europe have reportedly expressed interest in upscaling production of the battery.

As a result the new Li-S design seems to offer the best of all worlds: boasting four-times the performance of the best Li-Ion batteries on the market while significantly decreasing the environmental impact of manufacturing.

That inspiration allowed the creation of a bond between particles that accommodates stress and delivers stability not seen in any battery to date. The team's battery is simple, cheap to manufacture, and uses water-based processes that could lead to "significant reductions in environmentally hazardous waste". Further testing in cars and solar grids is planned for early 2020, leaving us hopeful that this tech could actually hit the mainstream in the next couple of years.
