Manufacturing method of lithium/thionyl chloride battery electrolyte material

[0016] A kind of preparation method of lithium / thionyl chloride battery electrolyte material, comprises the steps:

[0017] a. Measurement: In a dry environment with a relative humidity of ≤1%, weigh 16300g of thionyl chloride, 3160g of lithium tetrachloroaluminate, 180g of calcium chloride and 15g of metal lithium foil for water removal;

[0018] b. Operation: In a dry environment with a relative humidity of ≤1%, add measured thionyl chloride, lithium tetrachloroaluminate, calcium chloride and metal lithium foil into a flat-bottomed glass bottle in sequence, among which calcium chloride The amount of addition should be saturated in the lithium / thionyl chloride battery electrolyte, and then the materials are stirred for 6 hours with a magnetic stirrer, and the finished product is obtained after filtering the residual lithium foil and the reaction residue.

[0020] A kind of preparation method of lithium / thionyl chloride battery electrolyte material, comprises the steps:

[0021] a. Measurement: In a dry environment with a relative humidity of ≤1%, weigh 16300g of thionyl chloride, 2640g of lithium tetrachloroaluminate, 200g of calcium chloride and 15g of metal lithium foil for water removal;

[0022] b. Operation: In a dry environment with a relative humidity of ≤1%, add measured thionyl chloride, lithium tetrachloroaluminate, calcium chloride and metal lithium foil into a flat-bottomed glass bottle in sequence, among which calcium chloride The amount added should reach saturation in the lithium / thionyl chloride battery electrolyte, and then the materials are stirred with a magnetic stirrer for 4 hours, and the residual lithium foil and reaction residue are filtered to obtain the finished product.
