Abstract
The solid electrolyte membrane according to the present disclosure forms an ion conduction-interrupting layer therein by polymer phase separation under a high temperature condition, such as an increase in internal temperature of a battery, and thus interrupts lithium ion transport. Therefore, it is possible to prevent thermal runaway and explosion of a battery by the formed ion conduction-interrupting layer (also referred to as interrupting layer), and thus to improve the heat resistance and safety of the battery.
