Printable solid-state PRISS battery to change the shape of battery technology

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.

World's first "aqueous solar flow battery" outperforms traditional lithium-iodine batteries

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.

SALt lamp runs on a glass of water and two teaspoons of salt

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.

Next leg of Solar Impulse round-the-world flight pushed back to April 2016

The Solar Impulse team has announced that the completion of its round-the-world solar flight will now be postponed until next April. The batteries of the Solar Impulse 2 solar-powered aircraft sustained damage as the aircraft ascended to an optimal energy-management altitude of 28,000 ft (8,534 m) on the first day of its ambitious Japan-to-Hawaii flight. It is believed that a high rate of climb coupled with over-insulation of the gondolas resulted in irreversible overheating damage to the aircraft's batteries.

LG's hexagonal battery gives an extra charge to round smartwatches

If you want a smartwatch with week-long battery life, then you're better off with something like Pebble than a color touchscreen watch – they typically only last a day or two. But South Korea's LG Chem, the country's largest chemical company and part of the same corporate LG umbrella that also makes smartphones like the LG G4 and the LG G Watch Urbane smartwatch, reportedly has taken a step towards addressing the issue with a new hexagonal smartwatch battery.

Mr. Everything wireless speaker can jump start a car

In a very crowded marketplace, what can a newcomer to the Bluetooth speaker arena do to stand out from the crowd? Well, in the case of Mr. Everything, it's pack as much functionality and usefulness into a portable audio throwing box as possible. The water-resistant speaker comes with integrated emergency lighting, a wireless charging pad and enough stored juice to charge up a MacBook's battery twice or, as mentioned above, jump start a car. It's even got built-in storage. Not the flash memory kind, but somewhere to stow away essentials like protein bars or first aid supplies.

Flexible, fast-charging aluminum-ion battery offers safer alternative to lithium-ion

Researchers at Stanford University have created a fast-charging and long-lasting rechargeable battery that is inexpensive to produce, and which they claim could replace many of the lithium-ion and alkaline batteries powering our gadgets today. The prototype aluminum-ion battery is also safer, not bursting into flames as some of its lithium-ion brethren are wont to do. Read More
