Course, the scientists are rarely the ones with the skills to commercialize a product. Papers reporting advances in batteries in the lab are a dime a dozen; very few of these ever make it to production, either through lack of effort or funding, or because there's an insurmountable problem that's only apparent once they move out of the lab.
So, while I'm happy to note claims of the next big improvement in batteries (or FCEVs/H2 or whatever), until a company is formed with financing, has the necessary facilities and is ready for real-world D&T, I take any such claims with a huge pile of salt. And that pile doesn't go away until there's an actual commercial product you can buy, with specs and prices known. Everything else is just another Envia (or Edison FTM, as the development history of the Edison NiFe battery demonstrates).
