GREENSBORO – A Greensboro startup is the top winner in the TechCrunch venture capital showcase.

Called the Battlefield Cup, the judges for the tech news website chose Minerva Lithium over 19 other pitching companies.

You can watch the winning presentation at YouTube:

Here’s what TechCrunch wrote about the winners:

“Minerva Lithium has produced Nano Mosaic, a coordinated polymer framework that looks a bit like black gravel and extracts critical materials from brine in just three days. Minerva says that it can extract one metric ton of lithium using just 30,000 gallons of water, and it can do it in three days. Evaporative brine processing needs to evaporate 500,000 gallons of water to get to the same amount of lithium. Just one gram of this absorbent material has a surface area equal to that of a soccer pitch, which should give you an idea of just how little you’d need to extract a large amount of minerals.”
