TL;DR: It is reported for the first time that potassium (K) ions can electrochemically intercalate into graphitic materials, such as graphite and reduced graphene oxide (RGO) at ambient temperature and pressure.

TL;DR: All-component 3D-printed lithium-ion batteries are fabricated by printing graphene-oxide-based composite inks and solid-state gel polymer electrolyte, which can be extended to the fabrication of multidimensional/multiscale complex-structures of more energy-storage devices.

TL;DR: In this paper, the authors investigated the interaction of the Na ion with reduced graphene oxide (rGO) by in situ transmission electron microscopy (TEM) and observed reversible Na metal cluster (with a diameter of > 10 nm) deposition on a rGO surface, which they evidence with an atom-resolved high-resolution TEM image of Na metal.

TL;DR: Evidence of lithium intercalation in NbSe2 is presented as a technique capable of modifying the material properties of Nb Se2 for further study and is successfully demonstrated and presented.

TL;DR: Reversible transmittance modulation has been achieved with sandwiched nanocarbon thin films (containing carbon nanotubes and reduced graphene oxide) via electrochemical alkali-ion intercalation/deintercalation and it is found that a larger interlayer distance in few-layer rGO results in a significant increase in transparency in the infrared region of the spectrum, in agreement with experimental results.
