Abstract
Gallium-based liquid metals (GaLMs), most notably eutectic gallium-indium alloy (EGaIn) and Galinstan, have attracted considerable attention as emerging soft electrode materials due to their high electrical conductivity, low toxicity, and excellent deformability and processability. However, the fabrication of large-area electrodes based on GaLMs remains challenging due to their intrinsically low viscosity and a sharp increase in surface tension upon oxide layer removal under reductive potentials.
In this study, we present a GaLM composite electrode material reinforced with uniformly dispersed filler particles and oxides, which significantly enhances both processability and shape stability. Rheological analysis reveals that the incorporation of these additives modifies the viscoelastic properties of the composite, enabling simple blade coating under ambient conditions.
