  "textContent": "Provided are a lithium battery separator based on a reaction control agent, and a preparation method for a lithium battery separator. The lithium battery separator is prepared based on a high-molecular weight poly-p-phenylene terephthalamide polymer solution with low apparent viscosity. A preparation method for the high-molecular weight poly-p-phenylene terephthalamide polymer solution with low apparent viscosity includes the following steps: adding a reaction control agent in the process of synthesizing poly-p-phenylene terephthalamide from p-phenylenediamine and terephthaloyl chloride to obtain a high-molecular weight poly-p-phenylene terephthalamide polymer solution with low apparent viscosity containing the reaction control agent, where a concentration of the reaction control agent in the high-molecular weight poly-p-phenylene terephthalamide polymer solution with low apparent viscosity is less than 300 ppm, and the reaction control agent is a solvent which is miscible with the first solvent and capable of curing the poly-p-phenylene terephthalamide at the same time.",
