Electronic Energy in ICs

The filling of empty sites in the host introduces geometrical aspects regarding local stmctural effects such as (1) symmetry of the occupied site, (2) ordering in the van der Waals gap and (3) a global change in the structure with the c-axis expansion in the direction perpendicular to the basal plane of slabs. From the stmctural view point, the intercalated species can occupy either octahedral or trigonal prismatic sites between slabs of a layered compound. 

The operating potential of a cell is limited by the open-circuit voltage Foe. The potential difference across terminals of the battery when no current is being drawn (Eq. 1.6), is the difference in the electrochemical potential of the anode //a and the cathode juq. For a high-voltage cathode that is a semiconductor in nature, //c is the Fermi level [31], Let consider the case of the 4.7-V LiNii/2Mn3/202 (LNM). If the active transition-metal cation contains a localized i-electron manifold, the manifold acts as a redox couple, e.g., in LNM. Successive redox couples are separated
