[0014] A method for preparing a low-valent titanium chloride-containing molten salt electrolyte according to an aspect of the present invention includes the following steps: mixing an alkali metal chloride and / or an alkaline earth metal chloride with a predetermined amount of a metal chloride to form a mixture, wherein the The standard electrode potential of the metal ion in the metal chloride is positive than the standard electrode potential of the divalent or trivalent titanium ion; the electrode containing metal titanium is used as the anode, and the mixture is used as the molten salt electrolyte, and the cathode is configured for electrolysis to All the metal chlorides in the mixture are deposited on the cathode, and the obtained molten salt is the molten salt electrolyte containing low-valent titanium chloride.
[0015] Wherein, the compounding amount of the metal chloride (or in other words, the content of the metal chloride in the mixture) can be adjusted according to th...
example 1
[0028] Mix 550g potassium chloride and 440g sodium chloride (molar ratio is 1:1), add 5% copper chloride and mix well, dry at 120°C and put it into the reactor, after assembling the cathode and anode, Carry out vacuum dehydration at 300°C for 5 hours, then pour in argon, and raise the temperature to 750°C under an argon protective atmosphere to melt the electrolyte, then connect the cathode and anode power supply, the current intensity is 20A, and the anode current density is 0.1A / cm 2 Implement electrolysis and detect the content of copper ions in the molten salt system. When the concentration is zero, stop power transmission, pull out the anode and cathode, and measure the concentration of total titanium in the system to be 1.8%, and the valence state to be +2.
example 2
[0030] Mix 550g lithium chloride and 440g sodium chloride (1:1 molar ratio), add 8% NiCl 2 After mixing, dry it at 120°C and put it into the reactor. After assembling the cathode and anode, carry out vacuum dehydration at 300°C for 5 hours, then fill it with argon, and raise the temperature to 450°C under the protective atmosphere of argon to make the electrolyte After melting, turn on the cathode and anode power supply, the current intensity is 20A, and the anode current density is 0.5A / cm 2 Implement electrolysis and detect the content of nickel ions in the molten salt system. When the concentration is zero, stop power transmission, pull out the cathode and anode, and measure the total titanium concentration of the system to be 2%, and the valence state to be +3.
