The primary function of lithium ion battery separators is to electrically insulate ions from conduction, i.e., to prevent direct electrical contact between the positive and negative electrodes in the battery, but to allow free passage of ions. The battery separator is a polymer material with a microporous structure. The production process of the battery separator is that the modification agent with nucleation is added into polypropylene by utilizing the characteristic that the density of the polypropylene is different between different phases, so that the polypropylene is subjected to crystal form transformation in the stretching process, and a microporous structure is formed. The microporous structure of the battery separator determines its own performance and thus affects the performance of the lithium ion battery. The area density of the battery separator has this relationship with the porosity of the micropores: the surface density is increased, and the porosity is correspondingly reduced; conversely, the areal density decreases and the porosity increases. In addition, the areal density also affects the strength of the battery separator. Therefore, as an important index of the quality of the battery separator, it is necessary to accurately measure the areal density of the battery separator.
