An electric car has been tested that managed a huge 1,100 mile range on a single charge. A massive jump from current electric cars like the Tesla Model S which tops out at around 300 miles.
The secret to this super range is a type of battery technology called aluminium-air. This uses oxygen naturally occurring in the air to fill its cathode. This makes it far lighter than liquid filled lithium-ion batteries to give car a far greater range.
Phinergy, who created the battery, is an Israeli company who worked with aluminium specialist Alcoa Canada to create the batteries.
[...] Aluminium-air batteries drain turning the metal into aluminium hydroxide which can then be recycled to make new batteries. That will mean swapping out batteries every few months. But since it's so much lighter and cheaper than current efforts it should offer huge mileage and be affordable.

First saw an Al-air battery in a car at a trade show in the 1980s -- not a new idea. The problem at that time was low peak current. Stores lots of energy, but can't deliver high power bursts for acceleration.
TFA didn't really say much, but it seems like the Al-air battery in this test car is used in the same way as the range-extender engine in the Chevy Volt or other range-extended electric cars.

IANAEE, but couldn't you add capacitors or something like that to store up power for those sudden bursts of acceleration?
