“…The viscosity of the formulation was adjusted by addition of a fumed silica nanofiller, which also have been reported to have a positive effect on the ionic conductivity 22–25 . As shown by indentation experiments in our previous work, this formulation resulted in a mechanically stable, flexible film after an irradiation time of 10 min when utilizing a combination of camphorquinone and p ‐dimethylamino ethylbenzoate as photo‐initiator and 10 mol% TEG‐DMA as cross‐linker 15 …”

“…The GPE manufacturing was carried out based on the procedure reported in our recent publication: 15 The monomers benzyl acrylate (Bn‐A), benzyl methacrylate (Bn‐MA), poly(ethylene glycol) methylether acrylate (mPEG‐A, M n : 480 g/mol), and poly(ethylene glycol) methylether methacrylate (mPEG‐MA, M n : 500 g/mol) were mixed in varying molar ratios (Table 1), whereas the molar ratio of benzyl (Bn) to poly(ethylene glycol) (mPEG) groups was kept at 3/1. Depending on the polymerizable group of the monomers, two different cross‐linkers were investigated.…”

“…In our recent study, we presented a GPE consisting of a methacrylate‐based polymer matrix and an ionic liquid (IL) that provides the ionic conductivity 15 . It was designed to be printed directly on the electrode as a viscous paste that includes all components of the GPE and subsequently cured by UV‐polymerization within a few minutes.…”

Despite intensive scientific efforts on the development of organic batteries, their full potential is still not being realized. The individual components, such as electrode materials and electrolytes, are in most cases developed independently and are not adjusted to each other. In this context, we report on the performance optimization of a full‐organic solid‐state battery system by the mutual adaptation of the electrode materials and an ionic liquid (IL)‐based gel polymer electrolyte (GPE). The formulation of the latter was designed for a one‐step manufacturing approach and can be applied directly to the electrode surface, where it is UV‐cured to yield the GPE without further post‐treatment steps. Herein, a special focus was placed on the applicability in industrial processes. A first significant capacity increase was achieved by the incorporation of the IL into the electrode composite. Furthermore, the GPE composition was adapted applying acrylate‐ and methacrylate‐based monomers and combinations thereof with the premise of a fast curing step. Furthermore, the amount of IL was varied, and all combinations were evaluated for their final performance in cells. The latter variation revealed that a high ionic conductivity is not the only determining factor for a good cell performance. Next to a sufficient conductivity, the interaction between electrode and electrolyte plays a key role for the cell performance as it enhances the accessibility of the counter ions to the redox‐active sites.

“…The robust nitroxide radical 2,2,6,6tetramethylpiperidin1oxyl (TEMPO) was selected as the pendant group because it is one of the most reliable organic electrode‐active materials. [ 4,12–17 ] The rather bulky group would weaken the dipole interactions between the sulfur atoms and improve the solubility of the polymer. Furthermore, the introduced radical moieties can be used as redox‐active units in charge storage devices.…”

A poly(ethylene sulfide) backbone is introduced as the main chain of a radical polymer. Anionic ring‐opening polymerization of an episulfide monomer substituted with 2,2,6,6tetramethylpiperidin1oxyl (TEMPO), a robust nitroxide radical, yields the corresponding polythioether. Compared to the traditional poly(ethylene oxide) backbone, the new polymer shows a lower glass transition temperature (−10 °C), and about threefold higher solid‐state ionic conductivity. The polythioether is also shown to improve the charge/discharge properties of a cathode in solid‐state lithium‐ion batteries.
