Abstract
A method for improving a lifetime property and a charging rate of a lithium-sulfur secondary battery capable of both improving a lifetime property and a charging rate of the secondary battery by inducing a homogeneous reaction of the lithium-sulfur secondary battery by applying a charging rate differently for each section in a charging process of the lithium-sulfur secondary battery.
