More Information
Summary:It is related to a positive electrode active material for lithium secondary battery, and to a lithium secondary battery containing the same. To improve the battery characteristics of high-capacity positive electrode materials by simultaneously doping tungsten (W) element, which has an excellent effect on electrical conductivity, and boron (B) element, which is positioned on the surface to suppress the negative reaction of residual lithium and electrolyte solution.
