IF Tesla continues to grow as expected, we could see a worldwide shortage of Li-ion batteries

So each Model S uses 2000 times the amount of lithium-ion batteries that a laptop would use (And then multiple times that for tablets and portables). Considering that every indicator including Tesla’s own forecasts show  Tesla doubling production over the next few years, we might see a shortage of batteries if makers like Panasonic and Samsung aren’t able to keep up.  Something however tells me that Tesla is aware of the issue and is working on alternatives.
