In a LIB, the separator should wet easily in the electrolyte, which facilitates the process of electrolyte filling in battery assembly [9]. Fig. 1 visually describes the impact of different wettability of the separator toward electrolyte on lithium ion transportation. Good electrolyte permeation in the separator provides the paths for Li + ion migration.

The thermal runaway of a single battery will generate excessive heat and combustible gases such as hydrogen, methane, ethylene, ethane, carbon monoxide, and other hydrocarbons [6]. The heat generated by these combustible gases will heat the adjacent batteries, leading to the failure of the entire lithium-ion battery module [ 7 ].
