#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 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. The prototype battery features an anode made of aluminum, a cathode of graphite and an ionic liquid electrolyte,
all packed within a flexible, polymer-coated pouch. And unlike lithium-ion batteries which can short circuit
and explode or catch fire when punctured, the aluminum-ion battery will actually continue working for a short
while before not bursting into flames.""The electrolyte is basically a salt that's liquid at room temperature,
so it's very safe, "said Stanford graduate student Ming Gong, co-lead author of the study.
The aluminum-ion battery hits the target here, too, with the Stanford team claiming"unprecedented charging times"of just one minute for recharging the prototype battery.
The aluminum-ion battery has covered you there, too. Unlike typical lithium-ion batteries that last around 1, 000 charge-discharge cycles,
or other aluminum-ion battery lab attempts that usually died after just 100 cycles, the Stanford researchers claim their battery stood up to 7, 500 cycles without a loss of capacity.
This would make it attractive for storing renewable energy on the electrical grid.""The grid needs a battery with a long cycle life that can rapidly store
and release energy, "team member Hongjie Dai explains.""Our latest unpublished data suggest that an aluminum battery can be recharged tens of thousands of times.
It's hard to imagine building a huge lithium-ion battery for grid storage.""The experimental battery also has added the advantage of flexibility,
which gives the technology the potential to find applications in the burgeoning field of flexible electronics.
Furthermore, the researchers point out that aluminum is a cheaper metal than lithium, and the aluminum-ion technology offers an environmentally friendly alternative to disposable AA
and AAA alkaline batteries used to power millions of portable devices. Currently, one of the prototype battery's biggest shortcomings is its voltage.
Although Dai points out it is more than anyone else has achieved with aluminum, the battery only generates around two volts of electricity,
which is around half that of a typical lithium-ion battery. However, the researchers are confident they can improve on this."
"Improving the cathode material could eventually increase the voltage and energy density,"says Dai.""Otherwise, our battery has everything else you'd dream that a battery should have:
inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life. I see this as a new battery in its early days.
It's quite exciting.""The team's work is detailed in a paper published in the online edition of Nature
and the battery can be seen in action in the video below. Source: Stanford Universit t
#"Smart"facade keeps offices from overheating, without using any electricity Office buildings with plate glass windows may provide a nice view for workers,
but they're certainly not ideal when it comes to energy-efficiency. Among other things, the sunlight that pours through them can raise the temperature in the office,
causing the air conditioning to come on. Now, however, researchers from Germany's Fraunhofer Institute for Machine tools and Forming Technology have created a light-blocking facade for such windows that only kicks in
when exposed to strong sunlight and it's powered by that sunlight, too. The facade was developed via a collaboration between Fraunhofer and the Weissensee School of art in Berlin.

#Graphene device makes ultrafast light to energy conversion possible Converting light to electricity is one of the pillars of modern electronics, with the process essential for the operation of everything from solar cells and TV remote control receivers through to laser communications
In this vein, researchers from the Institute of Photonic Sciences (Institut de Ciències Fotòniques/ICFO) in Barcelona have demonstrated a graphene-based photodetector they claim converts light into electricity in less than 50 quadrillionths of a second.

they remain in that state and transfer their energy much more rapidly. As such constant laser pulse excitation of an area of graphene quickly results in superfast electron distribution within the material at constantly elevated electron temperatures.

but still using substantial metabolic energy, "Collins explained.""This is the opposite of regenerative braking. It's as if every time you push on the brake pedal in your car,
This is accomplished through the use of a mechanical clutch that produces force without consuming any energy.
To offset the initial penalty that sees an increases in energy costs when heavy objects are placed on the legs,
"said professor"The efficiency of the tunneling process depends intimately on the degree of alignment of the molecule discrete energy levels with the electrode continuous spectrum.
At the Molecular Foundry we developed an approach to accurately compute energy-level alignment and tunneling probability in single-molecule junctions.
"In addition to breaking symmetry, double layers formed by ionic solution also generate dipole differences at the two electrodes,
and energy flow at the nanoscale. What is exciting to me about this field is its multidisciplinary nature the need for both physics and chemistry and the strong beneficial coupling between experiment and theory.
#Aluminum"yolk"nanoparticles deliver high-capacity battery recipe 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
The lithium-ion batteries in our phones, tablets and laptops store their energy-carrying ions inside negative electrodes made of graphite.
Other electrode materials could in theory do a far better job by packing in more energy

like lithium or silicon, can store much more energy per unit weight than conventional graphite.
However, it isn't usually considered a good choice for building lithium-ion batteries because the repeated expansion and shrinkage inside the electrode cause aluminium particles to shed their outer layer.
the new electrode can reportedly store over three times as much energy per unit mass (1. 2 Ah/g) at a normal charging rate.
it could lead to batteries that are longer-lasting, more energy-dense and faster-charging than today's cells s

and therefore also carry relatively bulky batteries to power their transmitters. Though still in development, the engineers say their new system is superior to existing radio communications technologies in this field,
In this way, the coils act as inductors for the application of energy and the production of magnetic fields and allow the body itself to act as a sort of waveguide for those fields.
in turn, reduce battery requirements, leading to smaller and more efficient devices. In this way, not only could wearables
and monitors be made smaller with longer battery life, but it would also reduce the size of ingestible transmitters to something much easier to swallow."
because they are limited to using small batteries, said Jiwoong Park, a Ph d student in Mercier's lab. ith this magnetic field human body communication system,
we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices."
"According to the researchers, beyond the benefits of ultra-low-power energy consumption, magnetic field human body communication may offer greater security than current wireless communication technologies.
Power is produced from a 250w brushless DC motor combined with a Lifepo4 36 V, 3. 4 Ah battery,
The scientists also believe that their theoretical research points towards using boron-doped graphene to improve such things as lithium-ion batteries by controlling generated gas levels for optimum efficiency y
#A Smartphone Case That Recharges Your Battery from Thin Air How many times a day do you scramble around looking for a power cord

Turning smog into diamonds would require too much energy, but the designer, who has created also solar bike paths in The netherlands,
often leading to the lowest levelized cost of electricity (LCOE) in projects. Not only is increased annual production,
Key considerations include the total annual electricity production and the amount of electricity produced during hours
when electricity demand is at its highest. PV Watts is a useful tool for examining the tradeoffs involved.
The software predicts the power produced from a PV system under various configurations. If a sunny location like Albuquerque, New mexico is selected,
the software indicates a single-axis tracker would produce about 20 percent more energy compared to the same size (Wdc) optimally oriented/tilted fixed PV system.
A tracking system will also produce more energy when a utility most wants it --when electric demands are at their peak.
Generally speaking, single-axis trackers produce about 20 percent more energy compared to fixed-mount systems just about anywhere in the U s. However,
the amount of annual energy produced in a cloudy location like Seattle is only about 60 percent of a sunny area like Albuquerque,
and is positioned to be a very competitive source of electricity going forward. Tags: array technologies, solar tracker s

#Solarcity Has a New Plan to Make Distributed Energy an Integral Part of the Grid Solarcity has an idea for how to help California utilities tap their own customers as an integral part of their billion-dollar distribution grid plans:
put them first in line. The plan is called a istribution loading ordera variation of the state longstanding loading order that puts renewables and efficiency ahead of fossil fuel-fired power for large-scale power procurements and transmission planning.
In a white paper this week, Solarcity wrote that the structure could be a key lever for customer-owned distributed energy resources (DERS) to compete for billions of dollars of distribution grid projects being planned by the state big three utilities.
It would also put existing DERS in front of utility contracts and procurements for distributed energy, like Southern California Edison groundbreaking local capacity requirement (LCR) contracts last year. ur idea is to start with what there,

Energy prices are a blunt instrument when it comes to forcing behavior change. Even automated and aggregated DERS lack the always-on communications
and control between grid operators and, say, utility-scale solar and wind farms. Still there are methods to determine the effective load carrying capacity of distributed renewables at scale,
or predict the response of lots of household batteries and smart thermostats to rising and falling prices.
Solarcity proposes building some headroom into how the distribution loading order calculates the capacity of customer-owned DER,

#New Material Could Turn Water into Fuel Scientists have designed theoretically a new material that could help supply the world with clean energy by turning water into fuel,
which mimics the way plants absorb energy from the sun, could make the energy-sapping job of splitting water into hydrogen and oxygen relatively easy.
As well as potentially being able to produce hydrogen for fuel cells, the complex new material could also be used to turn carbon dioxide from the air into a carbon-based fuel,
such as methanol. Ricardo Grau-Crespo, from the Chemistry department of the University of Reading, led the team that made the discovery."
"Splitting water into hydrogen and oxygen is an energy-intensive process, which currently requires much more energy in from electricity than comes out in usable fuel.
To make the process more efficient, scientists use a photocatalyst-a material that absorbs light from the sun
as it can only absorb energy from ultraviolet light. The Reading-led team used supercomputer simulations to look at many different candidates as potential photocatalysts for fuel production reactions.
which allow plants to convert sunlight into chemical energy, "said Grau-Crespo.""The challenge now is to incorporate these wonderful natural catalysts into materials capable of doing the specific chemical job we need.
it could lead to highly-efficient conversion of solar energy to chemical energy-providing a clean, storable and transferrable source of energy. y
