Solid-state battery startup claims breakthrough for electric vehicles
Even if completely true, that technology will probably come too late for cars. With the current production (and sales) of Tesla, other carmakers have had to react one or two years ago (and it looks like they did).Expect an increase in the production and sale of EV by a factor of ten in the next five years, barring a global economic crash. That scale should easily drive down the cost of conventional LiIon cells below the cost of gasoline engines (you will probably be paying around 100$/kw/h or even less).In such a scenario there is not much room to develop and scale a brand new technology. It could be interesting for planes though.
