Exactly where is it..? You would think the DOE would have checked or validated the existence of the patent...
I would guess if you search for the patent you would find the Neah Power System out side of the range in the search field just like the shared patent with Clean Tech ....
Neah Power Systems has patented a three-dimensional porous silicon based lithium-metal battery that has demonstrated 1,500 watts per liter of volume and 500 watts per kilogram. This battery uses older generation computer chip manufacturing technology that is widely available throughout the world, enabling a low cost, which the company targets at $150 per kilowatt hour in high volume production. Such a low price point would make the battery applicable across industries, from small devices such as cell phones to larger applications for stationary power, automotive and grid-scale back up. Such a foundry model allows a low capital-cost ramp up into high volume production, with very high quality control. Through the SBV Pilot, the company will utilize Argonne National Laboratory staff and expertise to determine the optimal metallization scheme for porous silicon as well as reliable and reproducible processes and insights into possible causes of degradation, capacity fade and dendrite growth.
