Solid state electrolites (such as ion-conducting glasses) are nothing new. The problem is that conductivity of solid electrolytes (and especially that of glasses) is much lower than conductivity of liquid electrolytes. This is very difficult to change because it is based on physic's laws. Li-ion batteries commonly use organic electrolytes. They may not be too cheap and are flammable, but at least they offer acceptable power densities (which are still not too exceptional). With glass electrolytes power may fell below acceptable level. The article doesn't mention this problem. I don't think its likely energy density will grow a few times with glass electrolyte. Why exactly? Do they expect that glass electrolyte will take much smaller amount of space than a liquid one? If yes, why? Some expressions from the article are difficult to comprehend of believe in them instantly. For example: Batteries and capacitors store energy in different ways. What is good for a one is hardly good for another. High dielectric constant can be barely useful for a battery or a supercapacitor. Only for a dielectric capacitor.
