A smartphone with a five-day battery life may be in your future

New battery can power phone for five days

New battery could power a smartphone for 5 days

Further testing of the Li-S battery will happen in Australia in early 2020.

The news comes after last year's awarding of the Nobel Prize for chemistry to three figures crucial to the development of lithium-ion battery technology.

Researchers at Australia's Monash University have developed what they're calling "the world's most efficient lithium-sulphur (Li-S) battery", an ultra-high-capacity design that could quadruple camera battery life and run a smartphone for 5 consecutive days without a charge.

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".

We lost energy and confidence". "If we had kept the intensity of the first half in the second, we could have won". As first goals go, a derby victor in the FA Cup is not a bad way to get it.


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.

An approved filed patent (PCT/AU 2019/051239) is available for the scientists' manufacturing process, and prototype cells have been effectively developed by Fraunhofer Institute for Material and Beam Technology-the German R&D partners.

It also said that several of the world's leading battery makers have shown interest in upscaling manufacturing.

As of now, the team has received more than $2.5 million as fund from the Australian government and worldwide industry partners to test the battery in electric vehicles and solar grids.

SpaceX now operates the world's biggest commercial satellite network
Elon Musk's company SpaceX is in final preparations hours before launching 60 Starlink satellites into Low Earth Orbit. There will likely be at least one more batch of 60 Starlink satellites scheduled to launch before the end of January.


Inspired by unique bridging architecture (first recorded in 1970s detergent powders), the team engineered a method that creates bonds between particles-to accommodate stress and deliver a level of stability not previously seen in any battery. This reconstruction allows the batteries to withstand higher stress loads without a decline in capacity and performance.

A hallmark of the design is that it is simple and "extremely low-priced to manufacture".

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 favors high performance metrics and long cycle life", Hill said in a statement, "but is also simple and extremely low-priced to manufacture, using water-based processes, and can lead to significant reductions in environmentally hazardous waste".
