Abstract: An anode containing a multi-composite conductive agent and a lithium secondary battery including the anode are proposed. The anode may include an anode active material containing a carbon-based material and a metal-based compound, a binder, and a multi-composite conductive agent containing a carbon-based conductive agent and a metal-based conductive agent having different physical properties and shapes. According to some embodiments, the anode can increase energy density and also improve electrical conductivity and electron mobility.

Abstract: The present disclosure provides a separator, a lithium metal negative electrode, and a lithium metal secondary battery which include a solid superacid coating layer. The solid superacid coating layer suppresses a growth of lithium dendrites in a lithium metal secondary battery employing lithium metal as a negative electrode by improving a mobility and a reaction uniformity of lithium at an interface of the lithium metal negative electrode and an electrolyte solution. In the lithium metal secondary battery, the solid superacid coating layer comprising solid superacid material having a porous structure is formed on at least one of the lithium metal negative electrode and the separator.
