Batteries are holding everything back, but this company has a potential solution
But we've been forced to accept that we need to charge these devices every day, sometimes several times a day.Phones? Good luck making it a full day on a charge if you use it a lot.Advertisement
Not to mention some smartwatches like the Moto 360, which have been plagued with poor battery life.It's not the worst thing in the world, but when you realize that your powerful new smartphone is essentially running on the same battery technology as the 1996 Motorola StarTAC, you start to wonder why batteries haven't kept up.
In fact, it seems like the proverbial "they" are doing everything but improving the battery lives of mobile and portable devices themselves. Software gets more power efficient, and many phones are adding power-saving modes. It's gotten so bad that entire companies like Mophie, the maker of battery cases and external packs, exist simply to create accessories that extend battery life.
We're not done with lithium-ion just yetAdvertisement
The short answer? There's nothing else at the moment that can safely store more energy with as long a lifespan at a lower cost.
Lithium-ion is the best we've got.However, Chiang said lithium-ion-powered devices could at least double or even triple their performance in the near future, potentially leading to devices that last two to three times longer on a single charge.Advertisement
Their most recent lithium-ion battery design, which it announced in June this year, could add up to a 20% more energy storage than a conventional battery by replacing the inactive non-energy-storing materials in conventional batteries with active energy-storing materials.
How does it work?
In the lithium-ion battery that's powering most devices today, there are several microscopically thin layers (up to 25 microns thick) of inactive materials that don't add to battery's energy storage. They're merely structural supports for energy-storing active materials.Advertisement
Sounds good! Let's shoot it with a gun
Current conventional batteries can only take on a solid, rigid form, which means they can only fit in the solid, evenly shaped parts of your device. They'll explode if you try to make them anything but flat.24M's batteries aren't rigid; they're semi-solid. "You can take our batteries and fold them up like an accordion," Chiang said. "You can do Origami with our battery and it won't fail. It won't produce an internal short."Advertisement
To prove a point, 24M shot one of its batteries with a gun, and it continued to output energy without exploding.
But flexible batteries means a potentially huge leap in future design innovation because product designers won't be restricted to today's conventional battery limitations. They'd essentially only be limited by their imaginations.
Ingeniously, Apple developed a lithium-ion battery with an innovative stepped design so it can use up as much empty space as possible for its newest ultra-slim MacBook. It works, but the batteries are still rigid and it's not a long-term solution for design.Advertisement
More efficient batteries that can fold into paper planes are fantastic, but it's not going to be exciting if it's more expensive to make.
So it's a good thing that 24M's primary focus is to "reinvent li-ion battery to cut today's li-ion costs in half," as 24m's CEO Throop Wilder told Tech Insider.24M says its design reduces manufacturing costs. By a lot.Advertisement
Batteries will be much, much cheaper
In other words, a $12 million 24M factory can make as many batteries as a $1 billion conventional battery factory. That's an 88% reduction in manufacturing costs, and a 24M promotional video says its batteries will cost 40% less than a conventional battery with similar capacity, which could ultimately mean cheaper gadgets.
Mobile and portable tech companies need to take notice24M will begin large scale production of its batteries in 2017, it's currently focusing on grid and EV applications. But other device makers should also take notice, as 24M's relatively inexpensive battery manufacturing process could mean less expensive gadgets both for gadget makers themselves and the consumer.Advertisement
On top of that, more efficient batteries that can bend and flex in pretty much any position to fit in every nook and cranny of your gadgets could also mean longer battery life and brand new possibilities for design. Chiang and Throop made sure to reiterate that "the comformality, flexibility, and abuse tolerance of 24M's cell could be especially advantageous in wearable devices."
