Ford is facing a similar problem: it simply cannot get enough of the batteries to keep up with the demand for its Ford Escape and Mercury Mariner hybrid models, says spokesman George Pipas. Ford currently has access to only 24,000 of the special batteries under a contract it signed years ago, he says. "The supply of batteries is capped."
Global demand is ahead of global supply.
I quoted the following from an article in Time magazine earlier this year:

This has got to be the biggest problem currently for hybrid cars.
