Ok, I am interested in anyone with specific knowledge on this topic indicating whether the first order mental image I have of battery tech is correct?
The way I understand it is that the highest energy density batteries are your non-rechargeable lithium cells like watch batteries. Rechargeable lithium-ion cells have perhaps half the capacity due to the fact that they need to add measures that prevent these dendrites, as mentioned in the article, from forming. So the Holy Grail here is to develop a rechargeable technology that prevents the dendrite problem without sacrificing capacity so that you can get the best of both worlds? And that is what they are working on here with the solid state design. Am I close to the mark?
