When the temperature of the lithium battery reaches to 90 to 150° C., the composite slat layer will be molten and reacts with the electrochemical reaction system to passivate the active materials and decrease ionic and electronic conductivity. Therefore, the thermal runaway event and its derived problem are efficiently solved.
