performance. As was studied, good ionic conductivity and mechanical strength have been exhibited in a cross‐link of high molecular weight poly(oxy ethylene)s PEs [91]. Lee et al. have also reported a cross‐linked composite PE by polymerizing alkyl monomer and polyethylene glycol dimethylcrylate (PEGDMA) in LiPF6/EC [92]. The studies indicate that ionic conductivity and flexibility of the PEs are dependent on the monomer content.

Schematic illustration of the pictorial model of a preparation of a cross-linked polymer. Schematic illustration of the (a) General synthetic routes for P(NIPAM-fv [DAV]) IL gels and P(NIPAMBVIm-DAV) gels and (b) a schematic mechanism of thermochromic and electrochromic devices based on the prepared polymer gels.

      2.3.4 Ceramic Polymer Electrolytes

      Multiple advantages of using solid PEs in electrochemical cells are as follows:

      1 (1) Non‐volatility.

      2 (2) No decomposition at the electrodes.

      3 (3) No possibility of leaks.

      4 (4) Decreased cell price (such as PEO, PMMA, etc.).

      5 (5) Flexibility.

      6 (6) Lowering the cell weight – solid‐based cells do not need heavy steel casing.

      7 (7) Safety.

Schematic illustration of the evolutions of morphology of ceramic filler in SCEs.
