Any chance we see these batteries in cell phones eventually?

Who knows really. It would all really depend on how much current the battery can output and over how much time can it sustain a level current. Also you would need to factor in cost and package size, weight, heat output, etc. And who knows, by the time those get mainstream there may be a new battery technology that would be more promising. Usually ideas/products like this are built as a stepping stone to open funding to explore newer technologies.
