Carbon nanotubes have promised some incredible advances in power efficiency, but one of the most promising (and most realistic) is boosting the capacity of lithium-ion batteries by a factor of two in the near term, and eventually by five. Suddenly, your electronics that last all day will be lasting all week instead.
If you were given the Jeopardy! category "things that breathe," chances are your answer might be, "What are living creatures?" Chances are also high that your answer would not be, "What is a battery?" You'd now be wrong.
Cables are the bane of the existence of everyone with more than just one or two gadgets, and it seems like we're going to be stuck with them as long as wireless charging remains at the novelty stage. Luckily, we're surrounded by cables almost all the time (in the form of clothing), and electrifying those could be an easy way to pipe electricity to literal pocket chargers.
In the racing game, shedding weight is key towards going faster. A new technology has been developed that essentially turns carbon fiber and glass reinforced plastics into a power source — that means turning the car's frame into a battery instead of relying on hefty batteries.
As the world's population continues to grow, fresh water is becoming one of the most valuable (and contested) resources on the planet. Whether it's for drinking, agriculture, or keeping our armpits clean, we need more of it, and we now may be able to make that happen with little more than a fancy battery.
A team of University of Illinois engineers have developed a self-healing system restoring electrical conductivity to cracked circuits. The fix happens so quickly service disruptions don't occur. The team used their technique for self-healing polymer materials and adapted it for electrical conduction.
Termites manage to power themselves by eating wood, which is a pretty neat trick. Sony has just come up with a battery that does the same thing: feed it shredded paper or cardboard, and it produces enough electricity to run an MP3 player.
The first floor of the University of California's newest engineering building is soon to be powered by the equivalent 1.1M high-end lithium-ion AA batteries. If you are curious as to what this looks like, the 1.1 megawatt power supply is big enough to cover a 50-meter long Olympic size swimming pool. That's a lot of power.
Your watch battery isn't small. This battery is small. At six times thinner than a bacterium, Rice University's new battery is 60,000 times smaller than a AAA battery.
That feeling of smug you get with your sleek Macbook and its integrated battery may not be worth it anymore, as a security researcher has shown that Apple batteries are vulnerable to hacking. It's possible to brick the battery completely, or even worse, infect it with malicious code that not even a complete OS re-install can fix.
