Mechanisms of the Reversible Electrochemical Insertion of Lithium Occurring with NCIMs (Nano–Crystallite Insertion–Materials) by S. D. Han, N. Treuil, G. Campet, J. Portier, C. Delmas, J. C. Lassègues, A. Pierre

“…Indeed, by minimizing the size of the crystallites, the formation of defects is favored, particularly at the crystallite surface, acting as reversible (de)grafting sites of Li+. Also, the cation-anion bonding is weakened not only in the grain boundary region but also within the crystallite close to its surface: then the electrochemical insertion of Li+ takes place through easy bonding rearrangements.…”
