| description | The invention relates to an anti-settling silicon-based battery slurry and a preparation method thereof, and the battery slurry comprises the following chemical components in parts by mass: 20-100 parts of a silicon material, 1-5 parts of cold-induced heat reversible gel, 1-10 parts of a conductive agent, 1-5 parts of sodium carboxymethyl cellulose, 1-10 parts of ethanol and 100 parts of water, according to the preparation method, the characteristic that a cold-induced heat reversible gel aqueous solution such as gellan gum and available gum forms molecular cross-linking curing at the temperature below 40 DEG C and becomes a liquid state at the temperature above 60 DEG C is utilized, so that the battery slurry is solid at normal temperature and does not have flowability, and the spatial positions of the uniformly dispersed active substance and conductive agent are fixed by the gel matrix; therefore, the storage time of the aqueous battery slurry is prolonged, and the battery performance of the aqueous battery |
