New Aluminum Battery Could Recharge Your Phone in Just One Minute
The next generation of batteries is here! An ultrafast rechargeable battery thatâ€™s also cheap and long-lasting. And since the new material it is made of is aluminum, the new battery is a safer alternative to conventional lithium-ion and alkaline batteries we are using all around the world today.
For decades, Scientists have tried to use aluminum as material for batteries. The great benefits of aluminum over conventional lithium-ion and alkaline batteries that we are using today are that aluminum is cheap, bendy, and has low flammability and high-charge storage capacity. So far all attempts to develop a commercially viable aluminum-ion battery have been unsuccessful. But now for the first time in history, an international team led by Stanfordâ€™s Hongjie Dai have accidentally discovered a simple solution. Iâ€™m not a Scientist, but if you are really interested in the procedure, I would highly recommend you to check out this article (http://www.nature.com/nature/journal/vaop/ncurrent/full/nature14340.html#figures).
The battery is also ultra-fast charging and crazy durable. Unlike the hours some of us might spend charging our phones every night, the prototype of the aluminum battery has a charge time of one minute! And not just that but what most of us donâ€™t know is that the batteries for example in an iphone 6 are made to last for about 500 to 700 cycles, were the international team of scientists says that their new battery is able to do more than 7,500 charge-discharge cycles without losing its capacity.
Unfortunately, the technology is still not completely developed and wonâ€™t be on the marked any time soon. One battery generates about two volts of electricity. While thatâ€™s more than any other aluminum prototype thus far, thatâ€™s only about half the voltage of a typical lithium battery. That doesnâ€™t mean that it wonâ€™t come at some point though but it will take a little more research over the next years and then there should be nothing to stop the new era of batteries that are not just faster but also better for our environment. Also the scientists are confident in their next steps â€œImproving the cathode material could eventually increase the voltage and energy density,â€ Dai explains. â€œOtherwise, 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.â€
