Abstract
Disclosed is a polymer electrolyte having a multilayer structure including a first polymer layer providing mechanical strength against external force and a second polymer layer to secure a conduction path for lithium ions, wherein the first polymer layer includes an organic electrolyte containing an ionic salt in an amount of 0 wt % to 60 wt % based on a weight of a polymer matrix of the first polymer layer and the second polymer layer includes an organic electrolyte containing an ionic salt in an amount of 60 wt % to 400 wt % based on a weight of a polymer matrix of the second polymer layer, and a lithium secondary battery including the same.
