It's normally quite hard to get excited about portable chargers. But, somehow, Nokia has managed to make one that's... strangely irresistible. Read More >>

That vaguely familiar chap up there is the HTC One carrying an extra three or four stone in additional flab, thanks to the Mophie Juice Pack. In return for fattening up your phone you get nearly double the battery life, which is a trade off we suspect many will take. Read More >>

They say this new kind of super-battery isn't safe yet. But we don't care. We'll sign the disclaimer. If we can have more capacity in a smaller space AND it recharges quicker, we can live with the small risk of fire and burns. Read More >>

Every 72L of petroleum we refine leaves behind 227g of sulfur byproduct — far more than we can even pretend to have use for. Luckily, some ingenious researchers at the University of Arizona, may have devised a solution that transforms the rancid yellow element into a new breed of battery. Read More >>

Unless you're completely killing your smartphone's battery on a daily basis, you don't need to haul around a massive backup battery. A single emergency charge is all most of us need for those days when we talk or stream more than we intended, which makes the Tarot's 1,500 mAh capacity the perfect balance of size vs. power.

Give basically any piece of tech you carry around the time machine test. Jump ahead 50 years, and show off whatever anachronism of a gadget you brought along to a native. They'd laugh, obviously. But within the confines of our traditional tech specs, you know what they'd probably find most egregious? The battery. Read More >>

It's not all Samsung versus Apple in the tedious world of the mobile tech patent. Nokia and HTC are one of the many groups of companies currently at each others' throats, with a recent German ruling finding in favour of Nokia's patents. Read More >>

Yesterday, Boeing detailed its solution for the 787 Dreamliner's battery problems. It involves improving the battery itself; fixing the charging system and adding another layer of protection with an added enclosure. Boeing is still committed to lithium-ion batteries and this solution will allow Boeing to continue to use them in the 787. Read More >>

Two months after Boeing's new 787 Dreamliner was grounded, investigators are still trying to figure out what caused a battery on one of the planes to catch fire. Apex reports that the latest information indicates the battery was never fully tested. Read More >>

Implantable medical devices have come a long way since doctors installed world's first pacemaker in Arne Larsson's chest in 1958 but they've always been hamstrung by a reliance external power sources. However, a new zinc-air battery chemistry developed by Institute of Physical Chemistry in Poland could eventually provide its host's implants with an unlimited power supply. Let the cyborg revolution begin. Read More >>

Because batteries enjoy dying so much when we really need that last little bit of juice, low battery warnings really should be more animated than the plain "20 per cent of battery remaining". I don't know how many times I've ignored that message. But if the alert made fun of me and said something like, "Oh I'll just charge it tonight" You idiot, then my God I would listen to it so much more. Read More >>

If you're trusting enough to leave your £36-a-month smartphone resting on a table in McDonalds while you guzzle down some meat and bread, there's about to be a good reward for doing so -- free electricity from embedded tabletop wireless chargers. Read More >>

Lighter, less expensive and more energy dense than other secondary battery technologies, lithium-ion has become the dominant form of rechargeable battery today. It powers everything from mobile phones and laptops to cars and commercial jets. But there is one little problem — these batteries don't just short circuit, they explode into flames. Here's what goes on inside a lithium cell before it goes boom. Read More >>

Graphene doesn't need any introduction: it's the super material to beat 'em all. But this beautiful video demonstrates how it could transform the future of the gadgets you use everyday. Read More >>

The number one technological hurdle separating humanity from the Jetson Future we deserve is developing a reliable power supply. Even today, we're barely even able to keep out phones alive through the evening commute. But a radical departure in Lithium ion battery technology could help keep our power-hungry gadgets online for days, not hours. Read More >>
