Researchers at Stanford University have achieved a breakthrough in developing a new battery that can be charged in a minute.
Through a project named "An ultrafast rechargeable aluminum-ion battery," the researchers have devised the battery with aluminum ion instead of the standard lithium-ion batteries that power our smartphones. It contains an aluminum anode and a graphite cathode that produce up to 2 volts of power over thousands of recharge cycles.
Hongjie Dai, leading the research at Stanford, said, "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."
In spite of the breakthrough, the new battery still lags behind modern batteries which offer voltage up to 3.7 to 4.2V. Dai believes that improving the cathode material could plug the gap in the near future.
The new invention, if proven over multiple devices and long life-cycles, will be a boon for smartphonemakers and consumers alike. The aluminum-ion is much cheaper as well as combustion proof, meaning that there will be zero chances of the battery blowing up or burning out over heavy usage.
For us consumers, owning a gadget with a battery that gets charged up in a minute would surely be a major relief over modern batteries that need constant attention.
