Cambridge University researchers make lithium-air battery breakthrough

With the growing need to move to electric cars and design computers, smartphones, and other devices that have more efficient batteries, lots of research is being performed into next generation batteries. A group of researchers from Cambridge University has released a paper that shows a lab model for a lithium-air battery that has solved some of the major problems associated with the technology.

New silicon tech makes batteries lighter, more powerful

Researchers at the University of Waterloo have created an inexpensive silicon battery technology said to increase both the life span and performance of lithium-ion batteries. The work was done by chemical engineering professor Zhongwei Chen, as well as a team of grad students. Ultimately, the creation could usher in batteries that are both smaller and longer lasting than present batteries, improving their use in everything from electric vehicles to everyday gadgets.

Samsung Stripe and Band batteries are flexible, target wearables

When it comes to wearables, batteries are one of the biggest limitations. For all their features and flashiness, smartwatches still suffer from relatively poor battery life, and those batteries represent design limitations (or, conversely, the wearables’ designs limit the battery choices). Different research collectives and companies have been working on battery technologies to remove the shackles, and one of them is Samsung, which recently introduced its new Stripe battery.

Is phone thickness more important than battery life? [POLL]

Upon seeing the device HTC One A9 and finding that it has a battery a tiny bit smaller than expected, we got to thinking. At what price do we get a great design for a smartphone? Has it become more important to us to have a device that looks great than to have a device whose battery is large enough to last well through the day? We've not yet tested the HTC One A9 yet, of course, so we don't know how long it'll last on one charge, but the question remains: are we still sacrificing some features in order to attain others?

Microsoft envisions a battery system that adjust to your habits

We've said it before and we're saying it again. Batteries have now largely become the bottleneck of mobile computing and the new obsession for engineers. Being able to offer battery life that exceeds more than half a day, with the same amount of computing power and usage, and without bulking up the device is sort of like the holy grail these days. But while many manufacturers and researchers are investigating new types of batteries and materials, Microsoft researchers have a different idea: to use the same kinds of batteries we have today and let software do the work.

iPhone 6s’ battery is smaller, but it might not matter

As the iPhone 6s is revealed, so too are its parts meticulously examined by the public. In this case, the battery has appeared in one of Apple's own videos, complete with a note on how large it is. While Apple doesn't generally share the mAh capacity of their batteries, previous teardowns have revealed the size due to regulation requirements for capacities to be printed on all such lithium ion units. Today we find that the battery in the iPhone 6s is smaller than that of the iPhone 6.

XTRON USB-C power bank: charge your MacBook on the go

Maximas has unveiled its upcoming XTRON USB-C power bank for the new MacBook and other gadgets sporting USB-C. The power bank, much like competing devices we’ve seen in recent months, can power USB-C devices while on the go, including applicable laptops; the device uses chips from Texas Instruments, according to Maximas, and battery cells from Panasonic. Furthermore, the power bank offers a 4.2a output, as well as a regular USB port (USB-A) for charging your other non-USB-C devices.

Apple patent hints at MacBook with fuel cell power

It seems that the latest tech obsession these days are batteries and that fever is reaching beyond just smartphones and tablets. A newly published patent has revealed that even Apple is considering alternative forms of power source to fuel not its iPhones and iPads but its future MacBooks. And the technology it is mulling over is none other than fuel cells. In theory, a MacBook that bears a fuel cell battery, in addition to a conventional lithium ion one, can last for days, maybe even weeks, on a single charge.

Intocircuit 11200mAh portable battery mini-review

Though they take up little space in your bag, a portable battery is a godsend for frequent travelers, or for those times you end up being away from a charging station longer than anticipated. A portable battery is only as useful as its ability to charge your phone, however, and there's one big downside with most portable batteries: you can't see how much charge they have left, or you have to guesstimate using a few LED indicators. Enter the Intocircuit 11200mAh battery -- it has a built-in display showing the percentage of charge left, among other things.

Hydrogen fuel cell powered iPhone 6 can last a week

Now that we have smartphones with 2K displays, 4 GB of RAM, and eight 64-bit cores, batteries have become the next obsession for many smartphone makers and researchers. From quick charging batteries to safer batteries and now to eco-friendly batteries, the smartphone's power source is both a source of interest and potential profit to those can put down a stake first. British company Intelligent Energy might just be one of those, with its hydrogen-powered battery that can power an iPhone for a whole week before needing a recharge.
