Battery technology breakthrough as you can fully charge your smartphone in just one minute

Scientists believe they have had a breakthrough as a new battery that could fully charge a smartphone in just one minute and is better for the environment than present models.

This aluminium-based batteries could eventually replace the lithium ones seen in laptops and mobile phones in the near future.

Added to the unprecedented charging times of their aluminium prototype, the team said it was also safer than lithium-ion batteries as the battery is less prone to catching fire and more environmentally friendly than common alkaline models such as AA and AAA.

Several scientists have hailed it as a breakthrough in battery technology that went further than previous attempts using aluminium.

According to the researchers report: "We have developed a rechargeable aluminium battery that may completely replace existing storage devices, such as alkaline batteries, which are not good for the environment, and lithium-ion batteries, which occasionally burst into flames. Our new invention (battery) won't catch fire, even if you drill through it.

"Millions of customers presently use 1.5-volt AA and AAA batteries. Our invention rechargeable aluminium battery generates about two volts of electricity. The figure is higher than anyone has achieved with aluminium."

The prototype battery was reported to be more durable, withstanding more than 7,500 cycles of charging without any loss of capacity and surpassing previous aluminium batteries which dies after about 100 charge-discharge cycles, while a typical lithium-ion battery lasts only about 1,000 cycles.

"This will be the first time an ultra-fast aluminium-ion battery was built with stability over thousands of cycles," the report's authors stated.

The report further added that lithium batteries can "go off in an unpredictable manner" and mentioned a ban by US airlines Delta and United on bulk shipments on passenger planes.

And this new design could be used to store renewable energy of the electrical grid, the researchers suggested.

"Another feature of the aluminium battery is its flexibility. You can bend it and fold it at will, so it has the potential for use in flexible electronic gadgets. Aluminium is also a cheaper metal than lithium the report added."
