Samsung Develops 'Graphene Ball' Battery With 5x Faster Charging Speed (digitaltrends.com)
Heart44 writes: A number of outlets are reporting a Samsung laboratory breakthrough allowing smaller and faster charging lithium-ion batteries using three-dimensional graphene. Digital Trends reports: "Scientists created a 'graphene ball' coating for use inside a regular li-ion cell, which has the effect of increasing the overall capacity by up to 45 percent and speeding up charging by five times. If your phone charges up in 90 minutes now, that number will tumble to just 18 minutes if the cell inside has been given a graphene ball boost. What's more, this doesn't seem to affect the cell's lifespan, with the team claiming that after 500 cycles, the enhanced battery still had a 78 percent charge retention. The graphene coating improves the stability and conductivity of the battery's cathode and electrode, so it's able to take the rigors of fast charging with fewer downsides." The technical paper describing how the graphene ball works and how it's produced is published in the journal Nature.
I've been waiting a long time for a development like this.
Samsung's been really good at THAT...
Just curious, how dissimilar are these 'graphene balls' from buckyballs? Both are made from graphite, and are spherical.
Corruption is convincing someone that the selfless ideal is the same as their selfish ideal.
Good for more power-consuming spyware libraries to embed into apps/operating systems, snooping chips and always-on sensors/microphones/cameras.
To clone this tech, call it a ibattery and charge a arm and a leg for it in the next iphone.
But does it catch on fire faster too?
For the past decade-and-a-half or so I have read at least 80 reports of 'Breakthrough in Battery Technology'
All of them claimed to boost battery power, longer lasting battery, and faster charging time
If they are so much better, as claimed, I think the market would welcome them with open arms
Funny thing is no one bring them onto the market
Why is that??
Can you put a big-ass one of these things in an electric car to get reasonable charge times (like, around 5 minutes for around 500 miles)?
What phone takes 90 minutes for a full charge?
All the current Androids do 50% in 15 mins and 100% within 45 mins.
I smell bullshit.
With all the advancements in battery technology you would think the battery in my car would be a lot smaller by now.
I'm charging my S8+ ~1.5 a day. 500 charges means that after just 1 year the battery is at 78% of capacity, What happens after 1.5 years?
Even for those who charge only once a day, 500 charges is ~1.5 years, which is less than the common 2-year lifespan of the phone.
Increasing the battery density probably won't help either, as manufacturers will again make thinner phones instead of increasing capacity.
This is a great and all but can it turn your phone into a hand grenade? #Note7Forever ;)
Anons need not reply. Questions end with a question mark.
Sounds like it'll be the bomb
Is Blazing Fast!
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
... and laugh at all the people who said Tesla's recent announcements regarding charge rates can't happen.
Elon say's hello.
SUCK MY GRAPHENE BALLS NERDS
for their next flagship phone.
I have some ni-cads batteries here you can try out against a modern battery and then you can tell me they haven't gotten any better.
#4,593...that hasn't made it out of the lab. How many stories, about new battery tech, that would allow longer life, shorter charge times have their been in the past couple years?
The article was published in Nature Communications - Nature Publishing Group's open access journal. Nature itself is a journal that has 3-4x the impact factor of Nature Communications. This probably doesn't matter to most people but it is a way to gauge how novel/impactful the research was perceived by the scientific community.
Serious question: What's the shelf-life of a Lipo cell? I've looked at a bunch of datasheets and I can't find any specs on this. I'm not talking about the self-discharge rate but rather if I get a cell from the manufacturer, which is usually at 50% charge, and let it sit for several years without ever cycling it, what happens to the cell's performance? Does it lose the ability to hold charge? Does it lose the ability to deliver the rated current output? If it degrades over time, what's that degradation rate? If you know the answer, can you point me to a datasheet or research paper that spells this out?
The distinction between bombs and batteries is vanishing. Both technologies have the exact same goal, to cram maximum energy into minimum space, so it is inevitable that they will merge.
"Apple has courage. We have balls."
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
The paper is missing a very vital test/data to accurately predict the life time of a battery. If you measure the amount of energy a cell takes to charge and the amount of energy if can give after that charge (with high precision), you can pretty accurately predict the real world life of a battery. Accelerated life cycle testing isn't accurate for batteries.
Here's the thing: I must've heard of a new revolutionary battery technology at least once a month for the past 5 years or so.
The problem is always mass production.
Can Samsung churn out batteries with graphene balls for all devices that currently use Li-po batteries at similar costs and similar speeds?
If not, then it won't be replacing anything. And this story is yet another one for the archives.
1) They'll just make the battery smaller, I'd guess. Why would a company whose job it is to sell hardware want that hardware to disrupt their product cycle (cynical, I know)?
2) DON'T charge you battery to 100% or discharge to near-zero. I don't have links, but there are some neat articles around the internet regarding the chemistry of li-ion batteries and charge/discharge. It's shown that charging to ~80% and discharging to only ~40% allows the battery to last far far longer; that's what I do, and so far it's working out very well.

Revolutionary. Nuff said.
great balls of fire

There are different types of advances in batteries. Sometime someone come up with a new chemistry or design. In this case they were looking at a problem (degradation of the electrodes) that had a known solution (coating the electrodes with graphene) but there wasn't a manufacturing process to do it. So they have come up with a very innovative way to do it that should be "easy" to add to manufacturing. This is probably one of those incremental breakthroughs that is closer to reality than a lot of the others we seen.

Assuming production models actually live up to the hype the next question will be one of cost. If it costs twice as much to make but only gives you ~45% more storage and a faster charge time it's only going to find a few niche applications. If it is on parity with standard battery production costs then Samsung is going to get a lot of interest from a lot of applications (some grid storage, vehicle batteries, etc).
that's what I do, and so far it's working out very well.
"labor saving devices" are training you to take care of them.
