POSITIVE ELECTRODE COMPRISING GOETHITE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME

A positive electrode for a lithium secondary battery including a goethite having urchin shape as a positive electrode additive and a lithium secondary battery including the same. If the goethite having the urchin shape is applied to the positive electrode of the lithium secondary battery, there are effects that increase the charging/discharging efficiency of the battery and improve the lifetime characteristics, by adsorbing lithium polysulfide (LiPS) generated during the charging/discharging process of the battery.
