Pre-lithiated polyphenylene sulfide, polyphenylene sulfide-based solid electrolyte membrane, battery electrode sheet, quasi-solid-state lithium ion battery and method for manufacturing same

A method for manufacturing a pre-lithiated polyphenylene sulfide with a high solid solubility of lithium, comprising the following steps:

• placing N-methylpyrrolidone (NMP), lithium sulfide (Li2S), and lithium hydroxide (LiOH) into a high-pressure reactor with a stirring function to obtain a first mixture, and heating the first mixture to 150-250° C. for a high-temperature dehydration for 2-5 h, and then cooling the first mixture to 100° C. and adding 1,4-dichlorobenzene (p-DCB) to the first mixture for a first reaction at 150-250° C. for 80-200 min;
• dropwise adding hydrochloric acid in an identical amount as an amount of the LiOH on a molar basis to neutralize the LiOH, and removing the NMP and H2O by an evaporation or sublimation, to obtain a dry mixed powder;
• and
• to the dry mixed powder, adding a chloride ion complexing agent to obtain a second mixture, stirring the second mixture to homogeneity, and placing the second mixture in a sealed reactor for a second reaction at 150-250° C. for 80-200 min, followed by washing and drying, to obtain the pre-lithiated polyphenylene sulfide with the high solid solubility of lithium.
