    Awesome, more battery technology that gets announced and then is never heard of again. I'm pretty sure we've had about 10 game changing new battery technologies in the last few years, yet here we are with it still getting worse and worse each year.

    It's not getting worse, it's getting better, but you don't see the benefit of it because devices are getting more and more power hungry, so the crappy old battery that used to last 7 days in your bog standard phone seems better than the 3000mAh battery that only lasts a day in your smartphone

    But put that same 3000mAh battery into your old bog standard phone and you wouldn't need to charge it for a month or more

    That's pretty obvious tbh, I clearly didn't mean that they are literally thinking lets use an even older and worse battery technology that we used last year.

    Wrong, it is getting better and better each year

    Battery life, not capacity, although that's not actually increasing hardly, batteries are just getting bigger as the devices do.

    I was replying to you saying Battery Technology is getting worse and worse each year - which it is not.

    Life, yea, but that's not the batteries fault, it's the power the device is pulling increasing faster than the technology we have for battery capacity

    EDIT - And the manufacturers caring about weight and thinness over battery life

    Personally I'd prefer a thicker smarthphone with great battery life, than a thin one with crappy life

    If im not mistaking we are still ising the same batteries as we did 15years ago..

    If it wasn't for licensing, patents and safety regulations to blame for the most part this type of tech would have been with us today I think.

    Admittedly we have seen a lot of battery technologies posted here that never seem to get picked up in the mass market. But i assume that it was because even though it showed promise, it may have been fragile or even dangerous.

    These batteries here look great, but in the end it's about capacity, number of charge cycles, that kind of stuff.. Who wants a battery that charges in 30 seconds, but can only be charged a dozen times? Might be good for a vacation, or a photographer, but end the end, we need batteries with hundreds of charge cycles.

    And then we have to face the whole charger vs battery price. A charger the size of a laptop? that... might be a bit much, since it would cost a bunch too no doubt.
     
  12. Interesting, charging quickly is one thing, its the actual length of on screen battery life that needs to be increased really but hey this is still great news and will make our lives a lot easier.

    btw thats an S3 not an S4 lol.

    Well if this is a new technology that charges in 30 seconds, what's to say it can't do that millions of times? It's not the same technology we're using now, so might not have the same limitations

    15 years ago you had to charge your battery to 100% and discharge it to near 0% otherwise you ended up with a phenomenon called The Memory Effect or something similar, for example if you constantly charged your phone when it dropped to only 50%, after a while, 50% was the new 0% and you just lost half your battery capacity

    We use a different combination of materials to create the battery now, so that doesn't happen

    We will be needing really thick wires, and a nice house wiring, because let´s say a 3000mAh battery will be needing at least 360A to charge in 30 seconds.

    But a few years ago there was a new technology for lithium battery's which was silicon nano filaments/wires for the electrodes, that increased battery capacity by ten fold. Where is that?

    I am in a fairly unique situation where as I have basically all my phones I've ever had still, so just had a quick look and the oldest one I have to hand is a Sony Ericsson T68m from 2001, so 13 years old, that uses a Li-Pol battery which has no memory effect and are still used in a lot of phones today. More phones use Li-Ion now, but that's just because it's cheaper, the two types are very similar.

    According to Wiki it was certain NiCd and NiMH batteries that had that issue

    Yeah it was, but I don't think I've ever seen a mobile (cell) phone that uses them (a lot of house phones do though), they're normally used and still are for AA, AAA, consumer replaceable ones with external chargers. I've got older phones, but they're in the loft so can't check atm. Got one from the mid nineties.

    mA-h is a rating of capacity and not power, or the rate at which work is done, or energy is transmitted.

    360A would correct if we only had a 4V supply.

    My Note 2 Battery is rated at 3100mA*h or 11.78 W*h. Let's make is 12W*h for easier math. 12W*36000 / 30 sec = 1440W. It's quite a bit but we have PC power supplies with that rating. We also have microwaves rated at 1200W. All these things are plugged into your standard wall outlet. However, I don't see manufacturers allowing the consumer to play with such a high output chargers.

    USB 3.1 suppose to have a maximum rating at of 20V 5A (100W). I suspect if these batteries come into market, we would see roughly (1440W/100W * 30 sec = 432 sec) 7.2 minute charges which is still MUCH better then what we have now.

    Where I really want to see these batteries be used is for cars. Most notably the Tesla. As long as they have a lifetime of Lithium Ions or better, have similar capacity, and don't weight much more, they could make electric cars much more desirable to purchase.

    And also the 3000 mAh battery is larger then the old flip phone, so have fun putting it in something it's larger than without the aid of Doctor Who.

    PS: I am shocked and dismayed to find out that this forum does not have a TARDIS emoticon. I propose that we relentlessly bug Hilbert into obtaining such a emoticon. Thank you and good Guring (is that a word?)

    I just got rid of my last NiCd power tool at work worst battery technology ever.
