The breakthrough comes from an accidentally created synthetic metal nanoparticle that could solve some of the oldest problems for batteries.

#Stanford Researchers Created A Smartphone Battery That Charges In Only One Minute Last year, emarketer reported that the global smartphone audience passed 1. 75 billion people.
the demand for longer-lasting batteries will continue to increase. Fortunately, researchers at Stanford university are building an aluminum-ion battery prototype that speeds up the charging times.
And the aluminum-ion battery could eventually replace many of the lithium-ion and alkaline batteries used in many smartphones today. e have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries,
which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames, said Stanford university chemistry professor Hongjie Dai, the lead researcher of the project,
in an article by the Stanford Report. ur new battery won catch fire, even if you drill through it.
An aluminum-ion battery generally consists of two electrodes, one negatively charged anode made of aluminum and a positively charged cathode.
Professor Dai said that his team accidentally discovered that a simple solution is using graphite.
This is why the Stanford researchers placed the aluminum anode, a graphite cathode and an ionic liquid electrolyte inside of a polymer-coated pouch.
The electrolyte is essentially a salt that is liquid at room temperature so it is safe, according to Stanford graduate student and co-lead author Ming Gong.
Researchers have been interested in developing a commercially viable aluminum-ion battery for decades, but efforts have been largely unsuccessful.
What makes aluminum appealing is the low flammability, low cost and high-charge storage capacity. A major challenge with developing aluminum batteries is finding materials that produce sufficient voltage after repeated recharging cycles.
The ionic liquid electrolyte products used in Stanford aluminum battery pack are also slightly expensive because there is not enough demand for it.
Lithium-ion batteries are also potentially a fire hazard. This is why United airlines and Delta air lines banned bulk lithium battery shipments on passenger planes.
When Stanford drilled through its aluminum battery pouch it worked for a while longer without catching fire
which makes it much safer than lithium-ion batteries. Lithium-ion batteries also takes hours to charge,
but the aluminum-ion prototype at Stanford takes only one minute. The aluminum batteries developed at Stanford university are more durable than other batteries.
For example, aluminum batteries developed at other laboratories died after just 100 charge-discharge cycles. The aluminum battery developed at Stanford was able to withstand more than 7, 500 cycles without any capacity loss.
Lithium-ion batteries generally last about 1, 000 cycles. The aluminum battery is also flexible so it can be used in electronic devices that can fold and bend.
Aluminum batteries could be used for storing renewable energy on electrical grids. Electrical grids need batteries with a long cycle life to store
and release energy. Aluminum-ion technology is an environmentally friendly alternative to disposable alkaline batteries too.
The rechargeable aluminum battery created by Stanford researchers generates about two volts of electricity, the highest achieved with aluminum.
Before Stanford aluminum-ion battery is mass produced, the research team will have to improve the cathode material to increase the voltage and energy density.
The voltage of the aluminum battery made by the Stanford researchers is about half the average smartphone lithium battery.
The findings in the research will be published in a paper titled n ultrafast rechargeable aluminum-ion batteryfor the April 6th advance online edition of Nature. com. The other co-lead authors of the study

#Why Tesla Batteries Are Cheap Enough To Prevent New Power plants Last year, analysts hired by Oncor Electric Delivery Company were toiling away on a study of the costs
and benefits of installing enormous batteries on Oncor grid in Texas. The benefits would surpass the costs,
if Oncor could buy batteries for $350 per kilowatt hour of capacityr less. That was the break even point.
At the time, the cheapest utility-scale batteries cost twice that much, the analysts noted, and some cost nearly ten times that much.
and the analysts predicted batteries might reach the $350 point in 2020. They didn have to wait nearly so long.
Tesla Powerwall home battery unveiled late Thursday night, dominated energy news all weekend, but the real news was the price tag on its utility-scale big sister, the Powerpack:
$250/kwh. here nothing remotely at these price points, said Tesla product architect Elon musk. Earlier Thursday night,
I was covering a Northwestern University debate on the future of nuclear energy, in which the nuclear critic Arnie Gundersen predicted Tesla new utility-scale battery would render new-build nuclear plants obsolete.
The battery would be cheap enough to solve the reliability problem of intermittent solar and wind,
he predicted, providing a cheaper alternative to nuclear power 24-hour output. Gundersen predicted the cost of the utility-scale battery would fall to 2 cents per kwh of the electricity that passes through it
which in coming years would render renewable energy with reliable storage cheaper than a new nuclear plant.
Gundersen focused on the utility-scale battery, which we would soon learn to call the Tesla Powerpack,
but most of the chatter in the wake of Musk announcement focused on the home battery, the Tesla Powerwall,
which is both more expensive per kwh and less poised to reap benefits. Some writers noticed both batteries. he Tesla battery is better than
I thought for homes, wrote the author Ramez Naam in a review of Tesla new battery line. nd at utility scale,
it deeply disruptive. At Tesla price, utility-scale batteries have the potential to perform better than 2 cents per kilowatt hour where it counts the most:
on the customer electric bill. The capital cost of utility-scale batteries may be more than offset by their benefits, according to the Texas study,
and if deployed at the grid level, they could actually lower electric bills. Even modeling batteries $100 more than the Tesla, the Texas analysts concluded that storage arrayed across the grid should cause a typical consumer electric bill to fall slightlyrom $180 per month to $179. 66.
That not a remarkable number if one is looking for savings, but it a remarkable number if one expects new capital expenditures on batteries to increase electricity bills. onsidering both the impact on electricity bills and improved reliability of grid-integrated storage,
total customer benefits would significantly exceed costs, the analysts, from The Brattle Group, found. Here why, according to their study:
1. Power Purchase Cost Savings. Utilities without sufficient storage often have to purchase power during system peaks,
Batteries eliminate those charges. 2. Customer Bill Offsets from Storage Merchant Value. Utilities would make batteries available to independent companies participating in regional wholesale energy markets,
auctioning off battery capacity and returning most of the proceeds to customers by reducing their bills. 3. Avoided Distribution Outages.
By preventing blackouts, batteries would save residential customers about $10 a year and commercial customers an average of $700 a year.
An example: Socore, a Southern California Edison subsidiary, is installing Tesla batteries at two Cinemark Theaters to keep them in business
when the power goes out.)4. Deferred Investments. Typically, utilities need enough power plants to serve their customers at peak hours, not at average hours.
By using batteries to serve peak loads, they can invest in fewer power plants. They can especially avoid firing up expensive eaker plants,
which are usually fast-starting but inefficient natural-gas plants. They can also build fewer peaker plants in the future.
By deploying batteries along the grid where peak loads are greatest, they can also defer investments in transmission
and distribution infrastructure designed to serve peak loads. An example: Southern California Edison installed a battery in Orange, Cal.
and found that it both improved reliability of the grid and allowed the utility to defer replacement of a circuit for 5 to 7 years).
And remember, that with hypothetical batteries up to $100 more expensive per kilowatt hour than Tesla. n this analysis,
Customers would then receive offsetting reductions in retail electricity costs from the storage in the form of deferred investments, refunds from the wholesale market auction proceeds,
Tesla Powerwall and other batteries for the home should produce similar benefits, but not as powerfully:
Tesla is offering the utility-scale batteries in 100kwh battery blocks that are grouped in packs from 500kwh to 10mwh+.
Ramez Naam review also led me to a study by the Electric power Research Institute, which found the benefits of grid-level storage exceeded costs in nearly all examined scenarios.

and also as batteries improve. Gundersen based his 2¢estimate in part on improvements in cyclinghe number of times a battery can be drained
and rechargedhat Tesla is known to be working on, and that have begun already to appear in other batteries.
Analysts often assume batteries will cycle once per day, 1, 000 times. The Michigan company Xalt Energy markets a lithium-ion battery that it says can cycle 4, 000 to 8, 000 times.
Some lithium-ion batteries used to back up data servers are designed to cycle up to 10,000 times.
These achievements are likely to be exceeded soon by the next generation of batteries coming down the pipe.
More cycles mean longer battery life and lower cost per kwh. Booms, Busts And Billionaires: An ebook From Forbes Find out what happened to the oil industrynd where it headed next. oth solar
and batteries are not uelsbut rather technologies, Gundersen said. he extraction cost of fuels continues to rise,
while technology costs continue to fall. My Doctoral contacts at battery companies are confident that 2 cents is indeed here in the lab and on the horizon commercially.
It is all about the number of cycles that can be pulled from a battery. We still don know what cycling improvements Tesla has bundled into the Powerpack,
if any, and Tesla has responded not to a request for comment. Ramez Naam thinks that both Gundersen optimistic 2¢(for the Powerpack)
and my Forbes colleague Chris Helman pessimistic 50¢(for the Powerwall are outliers in the range of possibilities for the cost of electricity flowing through Tesla batteries.
If utilities get the same 10-year warranty Tesla offers to home customers, Naam estimates the Powerpack cost per kwh will be told 7,
Even at twice that price, he said, grid-level batteries offer utilities a return on investment now:
