The materials used for lithium ion batteries are expensive. Other, cheaper materials are available, but they are not typically used because they suffer from "capacity fade" -- that is, when you repeatedly cycle (i.e., drain and re-charge) them, they don't last very long, especially in warmer environments.
This means the less expensive materials can be used -- and this can help tremendously with the cost issues that are preventing the use of lithium ion batteries in some major applications.
We've received a lot of interest in the technology -- from a Fortune 500 company to a small but well-funded start-up. All of these companies are working in the battery or battery materials area and each of them plan to watch carefully as we bring the technology to full commercialization. They could very well end up being the technology's first licensees.
We will soon be submitting a Phase II proposal to fund the commercialization effort. We should have an answer on that proposal toward the end of the year.
