Reply to comment by tornpentacle in Scientists develop all-3D-printed lithium metal batteries with high energy density of 81.6 mWh/cm2, exceeding all reported 3D printed batteries so far by giuliomagnifico

Uhh, sure, but the thickness still matters. Your capacitance comes from the volume, not the area. If they're going to measure density in terms of area, they should specify the thickness. Or just divide by it and give the measurement in terms of volume, then people can directly compare technologies.

Why would they want people to be able to do that and weaken their funding generating hype machine?

Definitely, I've been told multiple times that it matters more than length.
