Hitachi Maxell develops battery technology that promises 60% more energy from the same volume

by: Andrew GrushMarch 28, 2013


Imagine getting 3,200 mAh of capacity out of something the size of a 2,000 mAh battery. That’s exactly what Hitachi Maxell’s new battery technology can do. This isn’t the first time we’ve been promised battery technology that can revolutionize the mobile world, but what sets Maxwell’s new tech apart is that it really exists and isn’t just a theoretical technology. However, before you get too excited, we don’t have a commercial product yet, nor a roadmap for commercial deployment.

Besides delivering 60% more battery capacity, Hitachi’s new process is also said to slow down the battery degradation process. The end result is that batteries won’t just stay charged longer, they will last longer, too. No this isn’t black magic at work, it’s science.

For those wondering how the technology was developed, Hitachi Maxell first set out to monitor the movements of Li-ions in real-time. Using this data, Hitachi Maxell was able to develop a battery structure that can resolve stagnation of Lithium ions. It is this process that allows them to pack more power into a smaller form factor, while also helping improve the length of the battery’s lifespan.

What does this all mean for the consumer? Let’s face it, modern octa-core processors, Full HD displays, and other high-end smarpthone features take a huge toll on your battery. Right now, manufacturers have two choices: give us awful battery life or add extra bulk to their phones in order to give you the battery life you need to make it through a workday. With Hitachi Maxell’s tech, we might not have to give up on thin phones to get the capacity we crave.

Hitachi Maxell has no word on when their technology will start shipping into actual devices, but here’s to hoping we see such tech sometime soon.

  • can’t wait to see this really happen. I’m already loving the 3 days i get out of my razr maxx on a single charge… imagine 60% better life

    • Mike A

      So 4 1/2 days.

      • shady

        Dual core is slow as shit

        • enomele

          Cause that’s exactly what they are talking about.

  • BatteryTroll

    Presuming this technology is backwards compatible with existing internal Li-Ion charging circuitry, what’s to stop this from immediately benefiting those lucky enough to have a replaceable battery (S3, S4, etc.). Hopefully OEMs and accessory makers have realized this and are already in development on such things. I know if I could improve my battery life by 50% for just $30-$40, I’d upgrade every device I own!

    • Daniel Armstrong

      For it to work in the SGS3, it will have to have an NFC antenna, since it is in the battery, and will have to be 3.8 volts nominal, there are 3 Li-Ion voltages, 3.6 which charges to 4.1, 3.7 charges to 4.2, and 3.8 charges to 4.3, actually 4.36 volts in my SGS3.

      We all know how bad over-volting a Li-Ion cell can be, IE the fire hazard.

    Is this really true? Or are you readying up for April fools day?? Seems too good to be true..If it is then its really amazing! or the greatest Invention of the smartphone era.

  • Larkhillv

    It would be awesome if this made it into this year’s Nexus phone. I doubt it will, but it’d be great nonetheless. I agree with BatteryTroll, though, and hopefully the next Nexus will come with a swappable battery.

  • mggOptimusG

    You drank too much kool aid !
    Sounds more like a Hitachi Maxell publicity stunt. LG Optimus G is also supposed to have a better battery with more charge cycles. The performance I get is just ok.

    It would be good to see a full review of batteries.

  • Jack

    Hitachi always does great things

    • mmm

      They just wave their magic wand around

  • MasterMuffin

    Hopefully this won’t result in thinner and thinner phones with smaller batteries >.<

    • fonseca898

      Because that would be awful, just awful.

      • MasterMuffin

        Think about it: if phones could get that extra 60% with same size, why go smaller? to get the old battery life back, because you’d miss bad battery life?

  • Dave Weinstein

    As others have said, the last thing we want is “a battery the size of a 2000mAh” one. Why does it always seem that any advance in battery technology is used as an excuse to reduce the size?

    WE WANT BIGGER CAPACITY BATTERIES!!! How difficult is it to get it through your heads?

    • blah

      and they are giving you a 3200mAh one that is the size of a 2000mAh one, so you ARE getting a bigger capacity, so its not difficult as per the article…

      • Paul Kopalek

        He means that OEMs will make EVEN THINNER phones now instead of increasing capacity. Which is the opposite of what people want!

        • blah

          But that’s not what he said at all and isn’t what is said in the article, you can assume that is what they are going to do but he quoted them stating the size of a 2000mah battery, so no change in size there, with an increase in capacity which is what he wanted, I think you guys just like being annoyed.

          • Paul Kopalek


            Dude, we know that.

            He’s not saying that it’s written there. He’s asking why it’s used as an excuse to make phones thinner and thinner (rather than battery capacities higher).

            Consumers overwhelmingly demand more battery life from their cell phones, not the next RAZR, or superthin version of the S3. They want more battery life.

            He’s just sending a message to anyone reading it, voicing his concern that this technology may be used to make the same battery capacity with thinner phones. Rather than make more battery capacity.

            Which is my preference, as well.

  • Technically that’s not battery power, it’s battery capacity.

  • And actually, the big.Little architecture (the Exynos Octa) is supposed to improve battery life. Same goes for Samsung’s full HD display, which they were saying at CES uses 25% less energy than their previous displays.

    This is what everybody has been saying for some time now, that we needed more money and time spent on cellphone battery R&D and look not even a cellphone OEM has doing it, its someone else..
