Battery

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.

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
When it comes to our phones, we could all probably use a little extra battery power and storage space. If you’re an iOS user, Mophie's new versions of its space pack for the iPhone 6, iPhone 6 Plus and iPad mini can help out with both. Read More
Next-generation lithium-ion batteries may hold more charge for a greater number of cycles thanks to a new material derived from natural silk. Scientists at the Beijing Institute of Technology found that not only does their regenerated silk fibroin material work for over 10,000 cycles but it also stores five times more lithium than graphite, which is the most common choice for the anode (negative electrode) in lithium-ion batteries.

A treatment process developed by engineers at the University of Colorado Boulder promises a simpler and more economical way to clean up the wastewater produced by oil and gas operations that is heavily salinated and full of organic contaminants. The technique, which involves the use of a microbe-powered battery, also produces rather than consumes energy. Read More
There's no shortage of phone cases with a built-in battery. A new one needs to do something interesting to stand out. In some cases this is done with a more powerful battery, or a smaller form factor, but in the case of the PWR Case, the new feature is a different method of keeping the case itself charged. Read More
Energizer has announced a new line of high-performance AA and AAA alkaline batteries that are in part made by recycling old cells, in what's claimed to be an industry first. Although currently only four percent of the battery comes from recovered materials, the plan for the company is to grow that percentage tenfold over the next 10 years and eventually use recycled materials in all its future cells.

Scientists at the Nanyang Technological University (NTU) in Singapore have developed a smart window that is able to tint itself blue, partially blocking incoming light, without the need for an external power source. The device also functions as a small transparent battery that recharges on its own simply by interacting with the oxygen in its surroundings. Read More
A new iPhone add-on devised by California-based company Peri aims to give iPhone users a double whammy: more battery power and sound volume, all for less cash. Called Peri Duo, it comes in the form of a case that integrates a speaker system and a 2,500-mAh battery. When detached from the phone, it becomes a speaker whose aural power is strong enough to disturb the neighbors. Read More
As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.
