  • POSITIVE ELECTRODE BINDER FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY POSITIVE ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING SAME
    Publication number: 20230238535
    Abstract: Disclosed are a positive electrode binder for a lithium secondary battery capable of improving battery performance, by being constituted by a cationic monomer, and thus capturing lithium polysulfide that occurs during charging and discharging of the battery, and a positive electrode for a lithium secondary battery and a lithium secondary battery comprising the same. The positive electrode binder for the lithium secondary battery comprises a cationic (meth)acrylate-based monomer containing one or more cations, or a derivative thereof.
