Separation membrane, lithium-sulfur battery, battery module, method for producing separation membrane, method for producing lithium-sulfur battery

摘要

The present application relates to a separation membrane and a lithium-sulfur battery including the same, and the separation membrane according to the present application prevents elution of lithium polysulfide in a cathode and suppresses growth of a lithium dendrite generated in an anode, and thus has an effect that a lifespan and safety of the battery are improved.
