The Front Cover illustrates the effect of hydrogen annealing on lithium titanate: creating oxygen vacancies in the crystal structure not only makes the white powder become dark blue, but also electrically much more conductive. As a result, lithium titanate allows for ultrahigh charge and discharge rates of lithium‐ion batteries. More information can be found in the Article by M. Widmaier et al. (DOI: 10.1002/batt.201700007).
