This invention discloses an aluminum-containing heavy water-based electrolyte, its preparation method, and its applications. The electrolyte comprises a solvent and a solute. The solvent includes heavy water, a deuterated solvent, and a low-barrier hydrogen bond reconstructing agent. The solute comprises a main aluminum salt and an auxiliary monovalent metal salt. This electrolyte can construct low-barrier hydrogen bonds in solution by controlling the solvent composition, significantly reducing the activity of water in the solution, improving the electrochemical stability of the solution, and suppressing side reactions. Simultaneously, it improves the electrochemical reaction behavior of aluminum in the solution and at the electrolyte / electrode interface, which is beneficial for improving the electrochemical deposition efficiency of aluminum in aqueous solution.
