I read so many breakthroughs in cell technologies lately, that I can't tell anymore what is research and what is success. Not being a specialist doesn't help either... So, are those plans based on real and tested batteries (as in, not just surface tests or whatever laboratory conditions), or thoughts how it would pan out if successful?
