content: There is plenty of promise in the lab and in prototypical form, especially when you look at nanostructures increasing anode/cathode surface area and subsequently electron storage density. These will be commercialized very soon.    The bigger deal is getting major volumes of the tech in the channel and actually available for sale in numbers that make a difference. Battery technology has been so actively suppressed over the past hundred years.    Tesla's stationary battery products have spurred a number of companies to compete and the segment is breaking out in a huge way. The benefits to our infrastructure and other technologies will be immense.
