The method includes determining a SOC of the secondary battery whenever a pulse current flows through the secondary battery; determining an electrochemical reaction resistance from a voltage change amount measured during a preset initial time in each pulse current section and determining a lithium ion diffusion resistance from a voltage change amount measured during a remaining time except for the initial time; determining a deterioration-biased electrode by comparing a deterioration diagnosing resistance ratio, which is a relative ratio of the lithium ion diffusion resistance to the electrochemical reaction resistance, with a preset reference deterioration diagnosing resistance ratio; and adaptively adjusting an operation condition of a next charging/discharging cycle according to the type of the deterioration-biased electrode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for controlling operation of secondary battery using relative deterioration degree of electrode","description":"Disclosed is an apparatus and method for controlling an operation of a secondary battery using a relative deterioration degree of an electrode.
