Samsung develops 5x faster charging battery

[HEXUS]

Graphene ball material delivers capacity increase of approx 45 per cent too.

So 5x faster than what? Standard charging or their super fast chargers? Also 45% increase is, I assume an increase in energy density. This is good for practicalities but remember that, despite the maturity of lithium cells, we still have them failing spectacularly. In this case we are packing in even more energy and there will be failure modes that are not discovered until they enter mass production. So what you have is an even bigger potential explosion in your pocket. This is going to be the case with every new advance in battery technology until we find one that fails safe but when you're talking about storing that kind of energy in a portable package, I doubt a truly, 100% safe battery is even possible.

Does it have 5x the chance of catching fire?

Well, they can't have it. It's got plenty of mileage left yet (unlike Samsung batteries!)

My s7 works fine, other than if I put it on wireless charger it goes so hot I cant even touch it, and thats when its at 100% charge... Obviously I wont charge it there, but still I bet there will be people dumb enough with same issue who will, and will burn their houses down

My S7 gets hot but not that hot...
Always good to bring new technology to market...

You do realise that the majority of issues with mobile devices are with 2 bits...the screen and the battery don't you? Apple for example have a high proportion of failures with batteries too but people seem less inclined to make something of it

In addfition to the concerns mentioned above, i have two questions :-

1) Cost? I know Samsung say "affordable" but that's rather subjective, certainly before we see device-specific examples. That is, compared to a smartphone battery or a Tesla battery?

2) Longevity? Whether for smartphone or Tesla, I want to know how long it's likely to last, and the 'maximum capacity over time' profile.


That said, any genuinely new working evolution in battery is, if it delivers, highly welcome.

Yes, but there is this thing called humour......and personally I like to apply it liberally. A big organisation which sells way too much stuff (due to their horrid marketing tactics) and then releases a lemon, are squarely in the firing line.

Samsung batteries bursting into flames and bending iPhones are at the top of the "things to be poked at" list

[3dcandy]

I agree.... but it's been a bit of a poo week and it's only Tuesday...

Reading from the Abstract: -

...along with a high cyclability of 78.6% capacity retention after 500 cycles at 5C and 60 °C.

Don't know how that compares to other cells. The micro-diamond arcticle mentioned here a month ago looked more promising in decreasing the capacity loss versus cycles.

500 cycles doesn't strike me as much. At 1/day, 18 months-ish. And depending on application, you may want more than 1 per day, such as a 400 journey in an EV that does 180 miles per charge. For a heavy-use cellphone, it may not be enough either, but for me, it'd last weeks

But what I really meant was the poiht at which a full recharge isn't really enough to be useable, necessitating battery replacement.

It's apparently early days yet for availability of commercial product, and besides, I want to see real- world independent results, not a manufacturer lab test under an entirely unknown test regime. After all, emissions testing by manufacturers was highly regulated/legislated, and we all saw what happened with VW et.al.

my phone takes 1hr plus to charge lol
