copper is stable. Nickel?

I'm continuing with this portfolio experiment.  People say copper is in the midst of a mining glut until 2017, so I'm in no rush to enter.  Nickel seems contingent on whether there will be a Nickel vehicle battery or better.  This is tricky for my portfolio, how to play nickel.  As an ethical fund manager in another life I would've endeavoured to bring about faster Nickel production where is being recycled economically (like a battery would be).
