  • HIGH-CONCENTRATION HIGH-ENTROPY ELECTROLYTE, METHOD FOR PREPARING THE SAME, AND BATTERY
    Publication number: 20250079522
    Abstract: A high-concentration high-entropy electrolyte and its preparation method and battery were disclosing in the present disclosure. A high-concentration high-entropy electrolyte, including a solvent, a first solute salt and added salts, the first solute salt is a solute salt with high solubility in the solvent, while the added salts are composed of at least three solute salts, the molar concentration range of the solute salts in the high-concentration high-entropy electrolyte is between 20 M-60 M, the molar concentration of the first solute salt is greater than 20 M, and the molar concentration of the first solute salt is greater than 50% of the molar concentration of the high-concentration high-entropy electrolyte. The sodium-carbon dioxide batteries assembled with high-concentration high-entropy electrolytes not only have higher power density, but also have excellent discharge specific capacity and rate performance.
