if you pass an electrical current through liquid potassium hydroxide would you get pure potassium metal as a product?

I was hoping to get some lithium so i could make my own Lithium salts to give nice red colours and not many places sell them. I have been told that manganese dioxide lithium batteries contain relitivly pure lithium. is this true?
All comments welcome

I have recently been finding it hard to find some of the chems i need like mg ribbon and potassium mangnate.
If anybody could shed some light on this topic it would be very much apreciated. I know of hobbychem but they have a real small selection.
All posts verry much appreciated,
Regards
