Lithium-ion batteries have become a real boom in the modern world. They replaced the heavy disposable alkaline batteries and are now used in everything, than only you can - from watches to electronics airliners. But since progress in electronics is not in place, then these lithium-ion batteries gradually begin to deal with constantly increasing demands for energetic sources. The only way out of this situation could 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 the new aluminum-ion battery development which is currently conducted by scientists from Stanford University. And if you believe the developers, the new batteries are not only less explosive compared to lithium-ion, but also have the ability to much more rapid charging. The charging of the batteries takes a little more than a minute. One minute!
But the more important facts related to the new batteries, according to Stanford scientists themselves, is the following:
"Our new batteries are not susceptible to fire. Even if they become damaged, "- says Stanford chemistry professor Dai Hong Ye.
In contrast to the early development of aluminum-ion batteries, whose life work was limited to about a hundred charge cycles, the battery prototype developed at Stanford University, is designed for more than 7,500 charge cycles without losing its energy capacity. And this is about 7.5 times larger than the average life of lithium-ion battery.
As acknowledged by scientists, aluminum-ion batteries in its current state is far from perfect. They are capable of producing a voltage of 2 V, unlike lithium ion batteries capable of providing a voltage of 3.6 V. In addition, the density of aluminum cells may be only 40 Watts / kg, in the case where lithium-ion media, this figure may vary from 100 to 206 W / kg.
"Improving the cathode material can contribute to an increase in the thickness and density of the stored energy," - says Dai.
"In all other respects, our new battery has everything you need for batareki-dream: cheap electrodes, high security, fast charge, flexibility and high uptime. And all this I see only in the early prototype. Prospects look really impressive. "
