  • METHOD FOR MANUFACTURING BINDER FOR COATING SECONDARY BATTERY SEPARATOR
    Publication number: 20230378602
    Abstract: Provided is a method for manufacturing a binder for coating a secondary battery separator, wherein the method may include performing a first polymerization on a first monomer to form a precursor solution including a chain-type particle, and adding a second monomer to the precursor solution and performing a second polymerization to form an emulsion particle on the chain-type particle. In an embodiment, the second polymerization may include an emulsification polymerization in which the chain-type particle acts as an emulsifier.
