in which ions transfer through the ceramic phase by means of vacancies or interstitials within the lattice. Typical examples of this are glass/glass–ceramic Li2S‐P2S5 and ceramic thio‐lithium superionic conductor (LISICON) Li4 − xGe1 − xPxS4 (0 < x < 1), which are the most promising electrolytes to increase ion conductivity up to 10−5 S/cm [117].

      The effects of ceramic fillers on the ionic conductivity of solid polymer systems have been discussed for quite many years. The published papers show that increasing the conductivity is the key parameter. Polymer‐ceramic composites offer superior mechanical properties and great conductivities. However, exploring ceramics materials is still a challenge.
