Abstract: This application provides a conductive slurry, a current collector, a secondary battery, a battery module, a battery pack, and an electric apparatus. The conductive slurry in this application includes the following raw material components: an aqueous binder including an aqueous polymer having polycarboxyl functionality, a conductive agent, a dispersant, and a curing agent, where the curing agent is used for cross-linking reaction with the aqueous polymer having polycarboxyl functionality. The conductive slurry in embodiments of this application has relatively good conductivity and adhesion performance as well as relatively good water resistance, which can improve stability of the secondary battery during operation and prolong its cycle life.
