Silicon and the Future of Battery Technology

There's almost a 10x increase in the capacity of silicon relative to graphite for storing lithium. And when all is said and done with the cathodes that are available today, we can demonstrate because we have all this capacity in silicon 500%. But we're not using all of the capacity. We're using roughly about half, almost 2 thirds. It takes advances in cathode for us to take advantage of our silicon to a greater extent.
