Faster Charging Batteries - and Cooler

[Ursa major]

A new manufacturing method for lithium-ion batteries could lead to smaller, lighter batteries that can be charged in just seconds.

Batteries that discharge just as quickly would be useful for electric and hybrid cars, where a quick jolt of charge is needed for acceleration.

The approach only requires simple changes to the production process of a well-known material.

Most commercial batteries use a material made up of lithium and cobalt, but lithium iron phosphate does not suffer from overheating - something that has affected laptop and mp3 player batteries in a number of incidents.

Now that's a good trick !!

FWIW, I miss the currents you could draw from those old-fashioned NiFe cells without letting out their 'magic smoke'...
