    Does this not also bold well for the electric car market that is suffering with poor battery capacity and charge times.

    I don't think having the battery drop to 50% of new after 150 charges is gonna be any good for the car market if I'm honest, people expect their cars to last a good few years.

    When can I buy one for my iPhone?!

    Re: Reviews - New Li-ion batteries offer 10x the capacity

    I'm sure it helps....but IMO the problem with cars is a completely different one....i.e. you still need to make the electricity and you lose a percentage of it as you transport it over distances...but that's a whole different topic!

    Never, iPhones don't have user serviceable batteries

    Re: Reviews - New Li-ion batteries offer 10x the capacity

    Researchers suggest that this technology could be seen in the market place in the next three to five years.
    Three to Five years? Really? I think that needs some Researcher Translation:

    Re: Reviews - New Li-ion batteries offer 10x the capacity

    Overall, some very promising steps forwards, though currently, this new technology does still lose charge over time, with the improved 10x capacity dropping to 5x after 150 charges. Mind you, if you find yourself charging your phone once per day, this new technology should enable charging of once per ten days initially, dropping to once per five days after 150 charges; given how infrequently a device would need charging, it would take around three years to reach 150 charges under these circumstances, at which point you still have five fold capacity over a current battery.
    Only 5x capacity after three years?! Oh that's just hopeless!

    Seriously though, if they can "productionise" this then good on 'em - I for one welcome the idea of having a smartphone that only has to be recharged as often as my works-issue Nokia 2330 dumbphone.

    To be honest, unless the new battery uses some particularly nasty compound that made it a bitch to recycle, then I'd be tempted to replace my battery annually and have that 10x capacity. Sure Apple would like the "annual replacement" push, since that'd fit their current product rollout schedules - because of course iPhone batteries aren't user replaceable.

    This new battery sounds ideal for personal media players - being able to play video for a day+ sounds fantastic!

    Career status: still enjoying my new career in DevOps, but it's keeping me busy...

    What I find promising about the approach is that it's not new tech as such, just a new approach to existing tech, so current tools and understanding could still be applied to most of the process, increasing the chances it'll make it to market. From what I gather silicon is the only change in material and that's found in most computer components so nothing exceptional there. The researchers will just have to spend the next three years proving that their batteries won't explode I suspect.

    Agreed.

    I bought my Cowon D2 in 2007. It had a battery life of 52 hours for music and 12 hours for video, I still get more than 40hours of music playback in use today. At the time it was ridiculous battery life to be able to listen to music for more than 2 days and get 5 movies played one after the other, not that you'd want to watch movies on such a small display though.

    I think this jump is long overdue. I want a phone that can last months on standby, weeks playing music and days playing video... once I can get that I'll get a smartphone.

    Re: Reviews - New Li-ion batteries offer 10x the capacity

    I suspect that instead of better battery life, what you'll get is an even thinner phone with the similar battery life as your current model. Especially if the industry keep up its current trend.

    Definitely moving in the right direction, but even with a 10x increase in charging speed, I still doubt it's going to be fast enough to compare with the ~1 minute it takes to fill a car petrol tank.

    And no matter how fast you make the battery capable of charging, at some point you also run up against the limit of the power you can get out of your wall socket.

    I'm sure that degradation due to charging can be mitigated with a battery management system (BMS is the reason why cars like the Prius still have good capacity after 100k miles).

    As scaryjim's illustration suggests, don't hold your breath. There was a similar big claim in regards to battery tech a few months ago using fluoride
