Introduction to Li Ion Adsorption

The high surface area and low average pore size generally offer more electroactive sites for Li-ion adsorption-desorption and avoid the stress upon the structure of the compound which resulted exemplary electrochemical performance.

Our work unveils the great significance of Li-ion adsorption in modulating the interlayer Schottky and tunneling barriers in vdW heterojunctions, thus improving their device performance.

Density functional theory (DFT) calculations reveal that unsaturated O coordination can be induced by electron transfer on Fe−O bond, which enables improved Li-ion adsorption on the surface of Fe-Ti3C2Tx nanosheet during charge/discharge process.

The experimental results and corresponding computational results reveal that the oxygen-activated surface of AMC, combined with the wettability and conductivity superiority of 3D graphite network, significantly facilitates the Li-ion adsorption and diffusion at the electrode/electrolyte interface, even at large thicknesses.

The formation energy, stability, electrical conductivity, Li-ion adsorption, Li-ion diffusion, and capacity have been compared.

Ferric hexacyanoferrate (FeHCF) or Prussian blue (PB) exhibits selective alkali ion adsorption and has great potential for use in various applications.

Li ion adsorption and diffusion mechanism on the (100) and (110) facets of Fe2O3 are explained by the calculations of density functional theory.
