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.
