Abstract
This invention discloses a safe and environmentally friendly modified graphene oxide-based hydrophilic gel electrolyte, its preparation method, and battery system, relating to the field of battery electrolyte technology. It aims to address the lack of low-cost, stable, and safe semi-solid gel electrolytes for zinc-ion batteries in existing technologies. The key technical points of this invention include: (1) mixing GO and CaCO3 in an ethylene glycol-water solvent, adding γ-glycidyl etheroxypropyltrimethoxysilane, mixing thoroughly to obtain a CGO mixture, adding TiO2, and synthesizing TCGO material; (2) adding deionized water to erythritol (ER) and sodium alginate (SA), mixing thoroughly to form a uniform ER / SA gel precursor; (3) adding TCGO material to the ER / SA gel precursor to disperse TCGO in the ER / SA gel precursor, obtaining TCGSA material; pouring the TCGSA material into a mold, defoaming and extruding, adding a mixed solution of soluble zinc salt and soluble manganese salt, and curing to obtain the TCGSA semi-solid gel electrolyte.
