#Solid-state Lithium-O2 Battery Featuring Integrated Electrolyte+Cathode Structure Shows Potential A new solid-state lithium-O2 battery featuring an integrated electrolyte+cathode structure developed by researchers at the Hong kong
The new battery was developed with the intention of dealing with two of the primary issues facing conventional solid-state Li-air battery performance:
The battery features considerably improved internal resistance (reduced), and an increase in triple-pause boundaries.
As a result, the battery outputs a discharge capacity as high as 14,200 ma h g-1carbon at 0. 15 ma cm-2,

#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.
Researchers have been interested in developing a commercially viable aluminum-ion battery for decades, but efforts have been largely unsuccessful.
A major challenge with developing aluminum batteries is finding materials that produce sufficient voltage after repeated recharging cycles.
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:
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,
Gundersen predicted the cost of the utility-scale battery would fall to 2 cents per kwh of the electricity that passes through it
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,
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,
At Tesla price, utility-scale batteries have the potential to perform better than 2 cents per kilowatt hour where it counts the most:
The capital cost of utility-scale batteries may be more than offset by their benefits, according to the Texas study,
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.
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,
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,
By deploying batteries along the grid where peak loads are greatest, they can also defer investments in transmission
Southern California Edison installed a battery in Orange, Cal. and found that it both improved reliability of the grid
And remember, that with hypothetical batteries up to $100 more expensive per kilowatt hour than Tesla. n this analysis,
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+.
is also purchasing Tesla grid-level batteries. e will also be using the Tesla grid scale system,
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.
Even at twice that price, he said, grid-level batteries offer utilities a return on investment now:
hat batteries bring positive ROI at such a price surprises lots of people. And it means windmills+batteries may be cheaper than nuclear plants right now,

#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,
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
