Stanford scientists have developed a new battery that would charge in a minute






Lithium-ion batteries have become a real boom in the modern world. They replaced the hard disposable alkaline batteries and are now used in everything in what only it is possible — ranging from watches and ending with the electronics of the aircraft. But as progress in electronics is not in place, these lithium-ion batteries gradually begin to face ever-increasing demands on energy sources. The only way out of this situation would be the development of new types of batteries that can meet all of our requirements for energy carriers.

One of these new types of batteries, for example, are new aluminium-ion batteries are being developed at the moment by scientists from Stanford University. And if you believe the developers, the new batteries not only less explosive than lithium-ion, but also have the ability for much faster charge. Charging these batteries takes a little more than a minute. One minute!

But the more important fact associated with the new batteries, according to Stanford scientists, is the following:

"Our new batteries are not affected by fire. Even if they become damaged," says Stanford chemistry Professor Dai Hong Ye. In contrast to early developments of aluminium-ion batteries, whose life was limited to about a hundred charge cycles, the prototype battery developed at Stanford University for more than 7500 recharge cycles without losing its energy capacity. And this is about 7.5 times greater than the resource average lithium-ion battery.

The confessions of scholars, aluminium-ion batteries in its current state is far from perfect. They are able to produce a voltage of 2 V, in contrast to lithium-ion batteries, capable of providing a voltage of 3.6 V. in Addition, the density of aluminum cells may be only 40 Watt/kg, when in the case of lithium-ion media, the figure can vary from 100 to 206 Watts/kg.

"Improvement of cathode materials may contribute to the increased power density and stored energy," says Dai."Throughout the rest of our new battery has everything you need to matariki-dream: cheap electrodes, high security, fast charging, flexibility and high uptime. And all this I see only in early prototype. The prospects do look impressive".
