Not relevant, IMHO. The paragraph was written a year ago. In the meantime, li-ion technology has improved in terms of its size limitations, but it is likely at its limit. You'll likely not see any li-ion batteries thinner than what is currently in the marketplace. Conversely, I believe that the li-poly technology is well-advanced beyond what could be commented on at the time. It is believed that it is now possible to mass produce li-poly cells only 1mm thick. This would provide Valence's battery with a TREMENDOUS advantage over the existing li-ion batteries. Another issue is safety. While true that the population-at-large takes the safety of li-ion batteries for granted, that safety was purchased at great expense of packing the battery in metal cannisters, and carefully controlling the recharging, etc. However, if the Valence li-poly battery has a much larger safety margin, I believe that this will once again become a significant marketing advantage. Finally, the issue of performance. We currently have no firm specs from the company about its batteries' energy densities, form factors, temperature ranges, etc. However, a PR statement from their Korean joint venture with Hanil Valence implied an energy density improvement of about 30% over li-ion, if I remember correctly, using existing Valence technology. I'm sure I speak for everyone here when I say we are all eagerly awaiting confirmation of the technological specifications later this year. As a final thought, consider how all the existing li-ion manufacturers are scrambling and tripping over each other to try to get to market with some form of li-poly battery. If nothing else convinces you of the true advantage of this technology, this should. Afterthought: Economic considerations may be a major factor as well. Our best guess is that the profit margins are much higher for this technology than for li-ion. But it's only a guess, at this point. OT, PS 'HellQat' has metamorphosed today...
