Scientists at Stanford have just hailed a breakthrough in technology that could provide safer, more convenient and a greener alternative for laptops and mobiles. Scientists say they have invented a new battery that could fully charge a smartphone in just…(wait for it)… one minute.
The researchers have created an aluminum battery which they hope could replace the lithium models commonly found in laptops and mobile phones. And as well as the “unprecedented charging times” of their aluminum prototype.
More so, this new aluminum-ion battery is something researchers have been pursuing because the material can be acquired cheaply, is not prone to bursting into flames, and is capable of storing a lot of power. However, the problem has been finding a good material for the cathode, one that will permit it to produce sufficient voltage after repeated cycles. In other words, to be rechargeable!
Publishing the findings in the journal Nature, Hongjie Dai, a professor of chemistry at Stanford University, hailed it as a breakthrough in battery technology that went further than previous attempts using aluminum.
We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames. Our new battery won’t catch fire, even if you drill through it. Millions of consumers use 1.5-volt AA and AAA batteries. Our rechargeable aluminum battery generates about two volts of electricity. That’s higher than anyone has achieved with aluminum.”
The prototype was said to be more durable, withstanding more than 7,500 cycles without any loss of capacity and surpassing previous aluminum batteries which died after just 100 charge-discharge cycles, while a typical lithium-ion battery lasts about 1,000 cycles.
Reports say, this was the first time an ultra-fast aluminum-ion battery was constructed with stability over thousands of cycles.
Dai added that lithium batteries could “go off in an unpredictable manner” and cited a ban by US airlines Delta and United on bulk shipments on passenger planes.
And the new design could be used to store renewable energy of the electrical grid, the researchers suggested.
Not only that, co-author Ming Gong stated that,
Another feature of the aluminum battery is flexibility. You can bend it and fold it, so it has the potential for use in flexible electronic devices. Aluminum is also a cheaper metal than lithium.”
