Zero‐Strain Insertion Material of Li [ Li1 / 3Ti5 / 3 ] O 4 for Rechargeable Lithium Cells
TL;DR: In this paper, a defect spinel-framework structure was examined in nonaqueous lithium cells and it was shown that the lattice dimension did not change during the reaction since the reaction consists of lithium ion and electron insertion into/extraction from the solid matrix without a noticeable change in lattice dimensions.
