Is the idea that they would stack the dodecahedrons into an approximate cube shape, or can they tweak the synthesis so that lithium cubes are deposited directly?
- rtkwe 3y agoThe latter. Though you can pack rhombic dodecahedrons with 100% efficiency I doubt you could get them to grow that way at an industrial scale. https://en.wikipedia.org/wiki/Rhombic_dodecahedral_honeycomb https://en.wikipedia.org/wiki/Rhombic_dodecahedral_honeycomb
- lazide 3y agoDepends on the economic value - we grow monocrystaline silicon at large scale now, for instance.
- rtkwe 3y agoSilicon has an inherently cubic crystalline structure and is way less reactive compared to lithium both of which help a lot. Maybe we could figure out monocrystalline lithium but the structure is a lot less forgiving.
