System and method for manufacturing lithium ion secondary battery

Abstract

A system for manufacturing a lithium ion secondary battery includes: an electrode assembly that includes a cathode electrode, an anode electrode, and a separator positioned between the cathode electrode and the anode electrode, and is impregnated with an electrolyte; a lithium part disposed on a surface of the electrode assembly, electrically connected to the cathode electrode or the anode electrode, and supplying lithium to the electrode assembly or receiving lithium deintercalated from the electrode assembly; and a controller allowing supply of lithium ions from the lithium part to the electrode assembly or allowing deintercalation of lithium ions from the electrode assembly.
