I design in supercapacitors (actually, they're called electric double-layer capacitors) in my company's products.

They can put out many, many amps for short periods of time.

I've been wondering when they would be combined with Lithium or LiPoFe batteries to create a replacement for a car battery.

This is a good development.

When will they make one for cellphones that will stay charged for a month?..........................
