The lithium-ion batteries that power everything from smartphones to electric vehicles carry a relatively low individual chance of failure, but the sheer quantity in use everyday means the risk of something going horribly wrong somewhere in the world is quite real. Looking to safeguard against such events, a team of scientists has developed a smart chip that can be embedded inside these batteries to monitor their health, offering a warning when it is at risk of catching fire or exploding.
Researchers at the Huawei Technology Corporation have unveiled a new quick charging lithium-ion battery. The development is said to result in batteries that charge ten times faster than conventional Li-ion batteries.
A new approach developed by researchers at the University of Waterloo could hold the key to greatly improving the performance of commercial lithium-ion batteries. The scientists have developed a new type of silicon anode that would be used in place of a conventional graphite anode, which they claim will lead to smaller, lighter and longer-lasting batteries for everything from personal devices to electric vehicles.
A new study suggests that the carbon-based waste material given off by burning candles could be suitable for use in larger, more powerful lithium ion batteries such as those used in electric cars. Two researchers from the Indian Institute of Technology found that as an anode material, candle soot compares favorably to existing commercial options because of its low cost of production and fractal-like nanoparticle structure.
The laws of supply and demand – maybe with a pinch of capitalism – generally dictate how much homes and businesses might spend per month on power. As such, consumers can expect to pay a premium for running heating or cooling systems during peak energy-usage times on cold or hot days. Orison Energy is preparing to help break this cycle with a pair of home batteries. The Orison Tower and Orison Panel charge up when utility rates are low and provide power when the rates are high.
If you run a lot of effects pedals, opening up hatches or unscrewing housings to replace 9 V batteries can be a bit of a chore, with many guitarists opting to build a pedalboard and juice up all of the stomps from one mains-supplied power pack instead. The 9 V Backpack from Züe Engineering allows a musician to quickly add battery power to a stomp without having to open up the casing.
It's a terrible feeling. You're already late for wherever you're going, so you rush into the car and slam the door shut. You put the key in, give it the usual twist and ... nothing, not a peep. Dead battery. Many a driver has experienced this issue at one point or another, and most would prefer not to repeat it. The Ohm smart battery was designed to help make sure you never do.
Researchers have created printable solid-state batteries that can be printed in any conceivable shape and can be seamlessly embedded into a variety of surfaces. To demonstrate the technology, the scientists printed a working heart-shaped battery onto a cup, another onto a paper eyeglass and even one in the form of the letters "PRISS", all of which were capable of powering LEDs.
The scientists that revealed the "world's first solar battery" last year are now, following some modifications, reporting its first significant performance milestone. The device essentially fits a battery and solar cell into the one package, and has now been tested against traditional lithium-iodine batteries, over which the researchers are claiming energy savings of 20 percent.
Many of the more than 7,000 islands in the Philippines lack access to electricity, so after the sun goes down light usually comes by way of kerosene lamps. While cheap, these fire hazards are bad for the environment and human health. This, combined with the cost of keeping them burning has given one startup the impetus to build a better solution. The SALt (Sustainable Alternative Lighting) lamp burns for eight hours at a time running on only a glass of water and two teaspoons of salt.
