SECONDARY BATTERY USING PRUSSIAN BLUE POWDER AS CATHODE ACTIVE MATERIAL AND METHOD FOR MANUFACTURING SECONDARY BATTERY

摘要

The present invention relates to a secondary battery using Prussian blue powder as a cathode active material . A secondary battery using Prussian blue powder as a cathode active material according to an embodiment of the present invention comprises: a cathode including a cathode active material part that receives electrons and is reduced and a current collector for supporting the cathode active material part; an anode including an anode active material part that emits electrons while being oxidized; and an electrolyte part which is a passage through which ions move between the anode and the cathode, wherein the cathode active material part comprises a Prussian blue powder, a conductive material, and a binder, and with respect to the total weight of the cathode active material part, the content of the Prussian blue powder is 78 wt% to 83 wt%, the content of the conductive material is 5 wt% to 12 wt%, and the content of the binder is 5 wt% to 13 wt%.
