What is it about?

In this work, we report the synthesis of a high ionic conducting and mechanically stable non-aqueous gel polymer electrolyte (GPE) for high voltage supercapacitor. A liquid electrolyte (LiClO4/propylene carbonate) is entrapped in a poly (2-hydroxy-3-phenoxy propyl acrylate) matrix by a UV assisted in situ polymerisation strategy.

Why is it important?

In this work, the strategy of UV assisted in situ GPE generation adopted for the fabrication of an all-solid-state, non-aqueous, flexible supercapacitor device is found to mimic an electrode–electrolyte interface close in nature to that of a liquid electrolyte. The existing trade-off between the higher solvent holding ability of the GPE and the mechanical stability is minimized to an extent by this work. An effective electrode–electrolyte interface is achievable irrespective of the electrode mass loading.
