Last year, eMarketer reported that the number of smartphone users worldwide exceeded 1.
There are 75 billion people.
With the popularity of smart phones, the demand for smart phones is increasing.
Lasting batteries will continue to increase.
Fortunately, researchers at Stanford University are making an aluminum
An ion battery prototype that accelerates the charging time.
And aluminum.
In the end, many lithium batteries can be replaced by ion batteries.
Today, many smartphones use ion and alkaline batteries.
\"We have developed a rechargeable aluminum battery that can replace existing storage devices such as alkaline batteries and lithium that are harmful to the environment-
\"Ion batteries burn occasionally,\" said Dai Hongjie, a professor of chemistry at Stanford University, in an article in the Stanford Report.
\"Even if you drill through it, our new battery won\'t catch fire. \"An aluminum-
The ion battery is usually composed of two electrodes, an anode with negative electricity made of aluminum and a cathode with positive electricity.
Professor Dai said his team accidentally found that using graphite was a simple solution.
That\'s why researchers at Stanford University put aluminum anode, graphite cathode and ionic liquid electrolyte inside the polymer --coated pouch.
According to Stanford graduate students and colleagues, electrolyte is essentially a salt that is liquid at room temperature, so it is safe

Researchers are interested in developing a commercially viable aluminum
Ion batteries have been unsuccessful for decades.
The appeal of aluminum is low flammable, low cost and high
Charging storage capacity.
A major challenge in developing aluminum batteries is to find materials that generate enough voltage after repeated charging cycles.
The ionic liquid electrolyte product used in Stanford aluminum battery pack is also a bit expensive because there is not enough demand for it. Lithium-
Ion batteries also have potential fire hazards.
That\'s why United and Delta banned lithium in bulk.
Battery Transport on the passenger plane.
When Stanford drilled through the itsaluminum battery bag, it worked for a while without fire-
This makes it safer than lithium. ion batteries. Lithium-
It also takes a few hours for the ion battery to charge, but aluminum-
The ion prototype at Stanford University takes only one minute.
The aluminum battery developed by Stanford University is more durable than other batteries.
For example, aluminum batteries developed by other laboratories died after just charging 100 --
Discharge cycle.
The aluminum battery developed by Stanford University can withstand more than 7,500 cycles without any loss of capacity. Lithium-
Ion batteries can generally be used about 1,000 times.
Aluminum batteries are also flexible, so they can be used in electronic devices that can be folded and bent.
Aluminum batteries can be used to store renewable energy on the Internet.
The grid needs batteries with long cycle life to store and release energy. Aluminum-
Ion technology is also an environmental alternative to disposable alkaline batteries.
Rechargeable aluminum batteries made by researchers at Stanford University produce about two volts of electricity, the highest level of aluminum.
Before Stanford\'s aluminum
Ion batteries are produced in bulk and the research team must improve the cathode material to increase the voltage and energy density.
Stanford University researchers make aluminum batteries that are about half the voltage of ordinary smartphone lithium batteries.
The results of this study will be published in an article entitled \"ultra-fast rechargeable aluminum-
