Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes, or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging and discharging. The new electrode, which makes use of aluminum/titanium "yolk-and-shell" nanoparticles, is reportedly simple to manufacture and is especially promising for high-power applications.
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.
There are already plenty of external back-up batteries for smartphones,
although they won't do you much good if they've lost their charge by the
time you finally need them. That's where the Nipper comes in. It
provides some extra juice to your phone via two easily-obtained AA
batteries, and is much smaller than most other AA-powered chargers we've
A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy and transforms it into either electricity or chemical energy used to split water and produce hydrogen for use in fuel cells. In an advance that could help this clean energy source play a stronger role within the smart grid, researchers at the University of Texas, Arlington have found a way to store the electricity generated by a PEC cell for extended periods of time and allow electricity to be delivered around the clock.
It's now fairly common to hear about batteries being used to store power
generated by solar cells. A group of Indian scientists, however, have
eliminated the middleman. They've created a battery that incorporates a
titanium nitride-based photoanode in place of a conventional anode,
allowing the battery to charge itself using solar or artificial light.
Following in the footsteps of Tesla and Mercedes-Benz,
Nissan is now set to become the latest automaker to offer battery packs
for stationary energy storage. Although pricing information has yet to
be provided, the Nissan product should be relatively affordable, as it
will incorporate used batteries from Nissan Leaf electric cars.
recently did it to much acclaim, and now Daimler is doing it too – the
German automotive corporation is launching its own home/business battery
energy storage system. Developed by Daimler subsidiary Deutsche
ACCUmotive, the Mercedes-Benz energy storage unit utilizes lithium-ion
batteries to store energy generated by solar cells, wind turbines or
Wood pulp-derived nanocellulose is turning out to be pretty useful
stuff. Previously, we'd heard how it could be used in things like high-strength lightweight composites, oil-absorbing sponges and biodegradable computer chips.
Now, researchers from Sweden and the US have used the material to build
soft-bodied batteries that are more shock- and stress-resistant than
their traditional hard counterparts.
Scientists have already devised systems that allow electronic devices to
scavenge power from ambient electromagnetic energy sources such as radio waves. While the technology has generally been limited to small devices such as wireless sensors,
a research team has recently created a scavenging system that charges a
smartphone's battery, letting it last up to 30 percent longer per
charge – and the system does so using radio signals emanating from the
