Apparatus And Method For Diagnosing Pre Lithiation

Abstract: An apparatus for diagnosing pre-lithiation according to one aspect of the present invention may comprise: a memory unit which stores a positive electrode reference starting value and a negative electrode reference starting value for a reference battery; and a control unit configured to obtain a positive electrode target profile and a negative electrode target profile for a target battery to be diagnosed, recognize a positive electrode target starting value and a negative electrode target starting value from the positive electrode target profile and the negative electrode target profile, and determine a lithium charge amount of a pre-lithiation process for the target battery on the basis of at least one of the positive electrode reference starting value, the negative electrode reference starting value, the positive electrode target starting value, or the negative electrode target starting value.
