Posco / Batteries / Tesla

So I have been doing some research this morning on POSCO to understand a little bit more about them.

Some interesting facts:
They supply the steel used to make the Tesla Model S
They are involved with PureEnergy Minerals who recently (16th Sept) signed a supply deal with Tesla for Lithium

If you have more information on POSCO post it in this thread so it can be discussed.
