A battery that’s only about half the weight of a typical laptop can recharge without a computer charger for the first time, scientists have discovered.
In fact, it can recharge with just one small USB port on the back.
The finding was published in a study that looked at how lithium-air batteries can be recharged in a lab setting.
The researchers were led by a team of researchers at the University of Texas at Austin, the University at Buffalo, and the Massachusetts Institute of Technology.
They used the Li-ion batteries that are the heart of smartphones and laptops, as well as rechargeable lithium batteries for electric vehicles and smart meters.
The batteries are a type of polymer that’s typically made of aluminum.
The polymer is porous and has a low surface area, which makes it ideal for being charged and discharged.
But unlike other types of batteries, lithium-airs are not liquid.
The battery’s surface area can also shrink and become more difficult to charge.
To help recharge the battery, the researchers designed a special electrolyte that’s designed to absorb the lithium ions in the battery’s liquid electrolyte.
When the battery is discharged, the liquid electrolytes become more porous and can absorb more lithium ions.
The scientists found that they could charge the battery in the lab and recharge it with just a single USB port.
“That’s the first of its kind,” said lead author Rong Xu, a postdoctoral researcher in materials science and nanoengineering at UT Austin.
“We can charge the batteries in a laboratory setting with just two USB ports.”
The researchers also discovered a method for recharging the battery that works even when the device is sitting in a car.
They tested the device by placing the device in a charging station and letting it sit for 10 minutes.
After that time, they placed it in a laptop charging station, where the device was charged by the laptop.
The laptop’s charging rate was the same, but the device remained charged.
Xu said they found the process of charging in a garage and charging in the car was more efficient than in a hotel room.
The new method could make the lithium-Air batteries cheaper and easier to recharge.
“The next step is to develop an improved charging solution that allows for rapid charging with minimal disruption to the environment,” Xu said.
“This method has the potential to be used for the energy storage market.”
The findings are part of a growing number of research findings that can recharge a battery in a way that isn’t dependent on a computer.
Scientists are finding that it can be done with just three to six USB ports on a laptop, according to Xu.
The findings could open up a new class of battery chargers that could power smartphones and other devices with low power consumption, or can even charge a computer without a power supply.
Xu is now working to design an improved way to recharge the batteries that can work without a USB port, and to figure out how to make the technology more cost-effective.
