Abstract

The Cover Feature shows, with tongue in cheek, the situation in the complex structure of NaSICON glass-ceramics. Inspired by the amusing drawing in van Gool's proceedings of the legendary first Belgirate conference on fast ion transport in solids in 1972, the picture shows how although the Na ions can easily migrate from one NaSICON crystal to the next, they cannot get any further at the boundaries to the glass and can only move with difficulty in the glass phase. Only along the tubular cavities can Na ions and protons easily slip through the glass areas and thus keep the overall conductivity high. More information can be found in the Research Article by F. Tietz and co-workers (DOI: 10.1002/batt.202500093).
