It's very approachable even for someone without a chemistry or EE background.
- baybal2 5y agoAnodes are really not a that big deal, even if you manage to replace them with a solid block of lithium. At max, they make 20%-25% of the modern lithium cell mass. So, even if you manage to just use lithium, you will still need few percents of it that for the lithium itself, and some mechanical spongy structure to hold it. Moreover, "solid" lithium implies solid electrolyte, and solid separator, which will also add to the mass.
