L. Andrews, Michael J. Brady, Eric T. McClure, Brent C. MelotOver the course of more than three
decades, Li-ion batteries have
come to revolutionize the way we store and transport energy. These
incredibly compact electrochemical devices rely fundamentally on the
ability to reversibly insert lithium ions into densely packed arrangements
of atoms. Of the tens of thousands of materials reported in the structural
databases, only a very small number have been shown to be capable
of accommodating the kind of fast ionic diffusion necessary to operate
in practical devices. In honor of John B. Goodenough’s 100th
birthday, this perspective will overview the current understanding
of the kinds of structural features that help and/or hurt fast lithium
ion transport through insertion hosts, with a particular focus on
the role that the rotation of rigid subunits plays in the movement
of lithium through the solid state.
