New battery could power your smartphone for 5 days

Researchers from Monash University in Australia have designed a smartphone battery which they claim can last up to five continuous days between charges.

Dr Mahdokt Shaibani from the university’s Department of Mechanical and Aerospace Engineering guided an international team to create an ultra-high capacity lithium-sulphur (Li-S) battery that boasts better performance than current lithium-ion (Li-ion) packs.

According to the team, the Li-S battery pack is the most-efficient of its kind, and its design could also be repurposed to build an electric vehicle battery capable of providing 1,000km of range.
 
Would be something that is very much needed in cell phones and electric cars for sure, I just wonder how long this tech goes from in the lab to on the street

Can already do it with the Lenovo P2 and probably other phones with beefier batteries as well. Manufacturers should just stick 5000 mAh + batteries in the phones.

Some newer phones are getting 5000mAh batteries, but 5000mAh still won't get you 5 days. My phone has a 4000mAh battery and manages 24-28 hours on average. Pretty great, and the best battery life I've had in a smartphone, but nowhere close to 5 days.
 
Ah yeah, my phone's battery used to last 10 days. When did 1 day batteries become the norm?
 
Even if they do it, they’ll just find other unnecessary stuff to put in the phones to use up that extra battery.

Yes obviously depends on if you're a heavy user or not. Some Redmi note 4 snapdragon users on here got 3 days per charge so hitting 4 or 5 days should be easily doable on 5000mAh. https://www.gsmarena.com/battery-test.php3

A new year and another new article about a revolutionary battery technology that never reaches market.

Admittedly battery technology has improved in recent years. It is just that the improvement has been incremental rather than revolutionary. These revolutionary ones never seem to pan out.

My first smartphone - an LG Optimus 2X - had a 1500mAh battery. It often didn't even last a day. My latest phone, a Xiaomi Mi A3 has a 4000mAh battery and could probably last just over 48 hours. It also charges faster. And all this without making the phones any fatter than they were - if anything, phones are thinner than they were.

Fair enough. If I charged my phone and just left it it would probably get to a week easily. But if I were using my phone that little I would question whether I even needed a smartphone in the first place. My wife had a RN4 Snapdragon and it never saw 24h on a full charge. I had the Mediatek version. They were both about 2 years old when we replaced them a few weeks ago. Neither could hold a charge anymore and had to pretty much live on a charger.
 
Wake me when this can be manufactured at scale and at a competitive price and not just in the lab in small batches.

At the end of the day it’s not all about high capacity in a small form factor. If the price is ridiculously high it will forever remain a nice case study.
 
They won't make the battery last 5 days if this ever does hit market, they will just ramp up functionality to use that extra power. People can generally charge once a day so it will just be bigger, more processor intensive apps and games to use that extra power.
 
a Could article, brilliant.

Also my elcheapo can last 5 day's, if its not doing anything.

I suspect they worked on overcoming these issues:

The key issue of Li–S battery is the polysulfide "shuttle" effect that is responsible for the progressive leakage of active material from the cathode resulting in low life cycle of the battery.[6] Moreover, the extremely low electrical conductivity of sulfur cathode requires an extra mass for a conducting agent in order to exploit the whole contribution of active mass to the capacity.[7] Large volume expansion of sulfur cathode from S to Li2S and the large amount of electrolyte needed are also issues to address.

Moar Processing Powa!, now there is something I can get behind.

/Waits for the day phones have enough juice to replace desktop rigs.
