Scientists might have reached the theoretical limit of how strong this particular material can get, designing the first-ever super-light carbon nanostructure that’s stronger than diamond.

The latest development in the nanoworld of carbon comes from a team that has designed something called carbon plate-nanolattices. Under a scanning electron microscope, they look like little cubes, and the math indicated that this structure would be incredibly strong, but it’s been too difficult to actually make, until now.

The team’s success was made possible by a 3D printing process called two-photon polymerization direct laser writing, which is essentially 3D printing on the level of atoms and photons.

Battery technology has come a long way and has an even longer way to go.

Subject Zero Science explains a recent innovation from Samsung.

Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency. To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide (NMC for short) mixed with a Sulfide Solid Electrolytes (SSE, show formula on screen), on top of nanocomposite-layer of Silver-Carbon.All of this is located in between a foil of Aluminum and Stainless steel as the current collectors.The idea behind this was to remove lithium foil from the mix and have all lithium atoms part of the NMC and SSE. This approach diminishes the costs of the overall battery manufacturing since handling lithium usually needs an oxygen free environment due to its high reactivity. This is important for a few reasons, in conventional lithium batteries, the anode comprised of lithium moves freely towards the positive electrode during discharge.Dendrites are formed during the charging process when lithium moves back to its initial location thanks to the free movement enabled by liquid or gel electrolyte.This is the main limiting factor of how much energy can be store in these batteries since to control this, the amount of lithium available in the system has to be caped, limiting the energy density.
