Polymer-based solid electrolytes

Schematic presentation of two possible mechanisms of ion transport in polymers: The liquid-like (lower left) requires the motion of the polymer segment and depends on the rate of segmental relaxation, whereas the solid-like (lower right) is based on ion jumps over an energy barrier in the frozen polymer matrix.

Inorganic solid electrolytes

Schematic representation of different mechanisms in lattice diffusion: (a) (mono)Vacancy mechanism. (b) Interstitial mechanism. (c) Interstitialcy mechanism. (d) Direct exchange and ring diffusion. (H. Mehrer, Diffusion in Solids, Springer-Verlag, 2007.)


Battery companies are testing a range of technologies in the quest to produce solid-state batteries (Roland Zenn, September 2020)
Many OEMs have announced their solid-state battery plans. (CIC EnergiGUNE)
