Fundamental scientific aspects of lithium batteries (VI)--Ionic transport in solids

Operating of lithium-ion batteries includes transport of lithium ion in anode, cathode and solid electrolyte interphase. It is important to determine the properties of ionic transport in solid state materials. In this paper, general ionic transport mechanisms in solids, driving force of ion motions, and factors affecting ionic conductivities are summarized briefly. Differences in the transport properties between intrinsic lithium ion in lattice and external lithium ion through lattice or grain boundaries and the size effect are briefly discussed as well.
