Nanoparticle‐Hydrogel composite with gelator molecules to form electrodes. a) Each (silicon‐nanoparticle) Si‐NP is encapsulated within a conductive polymer surface coating and is further connected to the highly porous hydrogel framework. b) Dispersion of Si‐NPs in the hydrogel precursor solution containing the crosslinker (phytic acid), the monomer aniline and the initiator ammonium per sulphate. c) Cross‐linked viscous gel formed after several minutes of chemical reaction, d) the hydrogel gel bladed onto a 520 cm2 copper foil current collector and dried to form the electrode.
