Scientists make battery breakthrough
 

A group of researchers at Stanford University claim to have invented an aluminium battery that will spell the end of lithium-ion batteries.

The batteries are made of a mix of graphite and aluminium and the Stanford scientists said that commercial production of the new style batteries could charge a smartphone in less than a minite.

Lithium-ion batteries have the tendency to catch fire, but the Stanford scientists claim the prototype they’ve built won’t do this.

And the aluminium prototype has shown in tests that it will charge much longer than comparable lithium-ion batteries.

The findings of the science are produced in the current edition of Nature. An aluminium ion battery has a negatively charged anode made of the metal.

Aluminium is also much cheaper than lithium so costs will be lower. The team said it still needs to make improvements for the battery to compete with the current technology.
