Abstract
A composite electrolyte membrane according to the present disclosure includes a phase change layer on a surface in contact with an electrode, for example, a positive electrode. The phase change layer includes a filler, and a physically isolated area between the positive electrode and the composite electrolyte membrane, known as a dead space, is filled with the filler that is liquefied by heat resulting from the increased internal temperature of the battery, thereby reducing the interfacial resistance between the electrolyte membrane and the electrode.
